--- title: "client.threads" description: "Every method in this namespace: its signature, its parameters, what it returns and an example." url: "https://openemail.uk/docs/ruby/reference/threads" area: "Ruby" category: "Reference" --- # client.threads Every method in this namespace: its signature, its parameters, what it returns and an example. ## Methods Read, search, label, trash and snooze conversations in the mailbox. ### `threads.list` List one page of threads in a folder ```ruby list(folder: nil, query: nil, label_ids: nil, sort: nil, date_from: nil, date_to: nil, from_contacts: nil, limit: nil, cursor: nil, api_key: nil) -> OpenEmail::Page ``` Returns one page of threads from the mailbox index, ordered by each thread's latest message with the newest first unless `sort:` says otherwise. A row is only `object` and `id`, so call `get` for the messages, labels and unread state. `sort:`, `date_from:`, `date_to:` and `from_contacts:` are the thread list's own controls: the four orders, a date range read against the newest message on each thread, and a filter to mail from saved contacts. Every order pages to the end, and a cursor carries on in the order it was handed out in, so send the same filters with it. `folder:` defaults to `inbox` and is matched against label ids after being upper cased, so `sent`, `archive`, `spam`, `trash`, `draft`, `snoozed`, `starred` and `unread` all work, `bin` is read as `trash`, and a user label id works as a folder too. A name that matches nothing returns an empty page rather than an error. `label_ids:` narrows the folder further: a thread must carry the folder label and every id you pass. `query:` takes the mailbox search syntax. Plain words must all appear, and each matches loosely: case, accents and separators are ignored and part of a longer word counts, so `min` finds "Benjamin". A quoted phrase is matched as written apart from case and accents, so `"ben jamin"` does not find "Ben-Jamin" while `"quarterly invoice"` finds "Quarterly invoice". When nothing matches exactly, close spellings are returned instead, so `benjimin` finds "Benjamin": a plain word, or the value of `from:`, `to:`, `cc:`, `subject:`, `body:`, `filename:` or `label:`, may differ from the start of a word by one typo when it has four to seven letters and by two when it has eight or more, while a quoted phrase, a word containing a digit, a shorter word and an excluded word still match exactly, and the pages that follow keep matching the same way. Filler words such as `the`, `about` or `emails` are dropped from a list of plain words when something else is left to search for, so `emails from john` searches for `john` alone. Operators such as `from:`, `to:`, `subject:`, `label:`, `is:unread`, `has:pdf`, `after:2026/01/31` and `newer_than:7d` narrow it, and `OR`, parentheses and a leading `-` combine them. Recipients are stored as one list without roles and never hold a Bcc, so `cc:` reads the same field as `to:` and `bcc:` matches nothing of its own. `from:me` is mail you sent, and `to:me` is mail carrying one of your own addresses, aliases included, among its recipients or as the address it was delivered to. Words and the `from:`, `to:`, `cc:`, `subject:` and `body:` operators read only the newest message on each thread: its sender, its recipients, its subject and the first 4,000 characters of its body with markup stripped. `filename:` and `has:` read every attachment on the whole conversation, and `label:`, `in:` and `is:` read the whole conversation. A plain word also matches the name of any attachment on the conversation, whichever message carried it. A sealed message has no body text to match. The search stays inside `folder:` unless the query names a folder itself, with `in:` or a folder `is:` such as `is:sent`, and `in:anywhere` searches every folder, on its own as well as beside other terms. A drafts listing is the exception and stays in drafts whatever the query names. Dates read the newest activity on the thread, in UTC. `after:` includes the day it names and `before:` excludes it, and a date can be written `YYYY/MM/DD`, `YYYY-MM-DD`, `YYYYMMDD`, as a bare year, or as epoch seconds or milliseconds. A short date reads day first (`16/09/2026`), unless the second number cannot be a month (`09/16/2026`), and a number above 12 settles it either way. The API pages with an opaque `pageToken`, which the SDK hands back as `next_cursor` and accepts as `cursor:`. Scopes: `threads:read`. **Parameters** - `folder` (`String`): Label the threads must carry, case insensitive. Defaults to `inbox`, and `bin` is read as `trash`. - `query` (`String`): Mailbox search. Plain words must all appear and match loosely, a quoted phrase has to appear as written, filler words are dropped when something else is left to search for, and operators such as `from:ada`, `has:pdf` and `in:anywhere` narrow it. - `label_ids` (`String or Array`): Label ids a thread must all carry on top of `folder:`, matched exactly. An Array is sent comma separated. - `sort` (`String`): `newest` (the default), `oldest`, `sender` or `subject`, the four orders of the thread list in the app. `sender` and `subject` are alphabetical, newest first within one sender or subject. - `date_from` (`Time, DateTime or String`): Keeps threads whose newest message arrived at or after this instant. A `Time`, a `DateTime` or an ISO 8601 string with a time and an offset. - `date_to` (`Time, DateTime or String`): Keeps threads whose newest message arrived at or before this instant. Both ends are included, and `date_from:` after `date_to:` is a 422. - `from_contacts` (`Boolean`): When true, keeps only threads whose newest message came from a saved contact. A key limited to some addresses reads the contacts its owner saved. - `limit` (`Integer`): Threads per page, a whole number from 1 to 100. Defaults to 25. - `cursor` (`String`): The `next_cursor` of the previous page, passed back unchanged. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** An `OpenEmail::Page` with `items`, `has_more?` and `next_cursor`. Each item is a Hash with `object` set to `thread` and `id`. **Example** ```ruby page = client.threads.list(folder: "inbox", query: "from:ada has:pdf", limit: 50) last_week = client.threads.list(sort: "oldest", date_from: Time.now - (7 * 86_400), from_contacts: true) puts last_week.items.size p page.items.map { |thread| thread[:id] } if page.next_cursor next_page = client.threads.list(folder: "inbox", query: "from:ada has:pdf", limit: 50, cursor: page.next_cursor) puts next_page.items.size end ``` **Notes** - The server offers a cursor whenever a page comes back full, so `has_more?` can be true on what turns out to be the last page, and the next call then returns no items. - Threads that arrived in the same instant are ordered by id, so a page boundary between two of them never skips or repeats one. - A thread that receives mail while you page moves ahead of the cursor and is not returned by later pages. - A value `query:` cannot use is ignored rather than narrowing, so a typo in a value widens the result instead of emptying it. That covers `category:`, `larger:`, `smaller:`, `size:`, `messagesize:`, `list:`, `rfc822msgid:`, `received:` and `sent:`, the category words such as `is:promotions`, a `has:` word naming no kind of attachment, an `importance:` other than `high` or `low`, an unreadable date and a duration whose unit is not `h`, `d`, `w`, `m` or `y`. An operator name it does not know, `project:` for instance, is searched as plain text. - A narrowed key only sees threads delivered to the addresses it covers, every address on a whole domain it holds included. A thread still has to carry the folder and every one of `label_ids:`, the same as for any other key. Also available in: API [`GET /threads`](https://openemail.uk/docs/api/reference/threads#get-threads); TypeScript [`threads.list()`](https://openemail.uk/docs/sdk/reference/threads#list); Python [`threads.list()`](https://openemail.uk/docs/python/reference/threads#list); CLI [`openemail threads list`](https://openemail.uk/docs/cli/reference/threads#threads-list). ### `threads.list_all` Collect every thread in a folder into one array ```ruby list_all(folder: nil, query: nil, label_ids: nil, sort: nil, date_from: nil, date_to: nil, from_contacts: nil, limit: nil, cursor: nil, api_key: nil) -> Array ``` Walks every page with the same filters as `list` and returns once the last page is in, so the whole result sits in memory at once. That suits a label view or a small folder. For a large inbox, `iterate` lets you stop as soon as you have what you need. Each request asks for `limit:` threads, 25 when you leave it out, so raising it to 100 needs a quarter of the round trips. Passing `cursor:` starts the walk from that page instead of the first. The walk ends when the server stops offering a cursor or hands back the one it was given. A failure on any page raises out of the call and discards everything collected so far. Scopes: `threads:read`. **Parameters** - `folder` (`String`): Label the threads must carry, case insensitive. Defaults to `inbox`. - `query` (`String`): Mailbox search, as in `list`. Plain words must all appear and match loosely, a quoted phrase has to appear as written, filler words are dropped when something else is left to search for, and operators such as `from:ada`, `has:pdf` and `in:anywhere` narrow it. - `label_ids` (`String or Array`): Label ids a thread must all carry on top of `folder:`, matched exactly. - `sort` (`String`): `newest` (the default), `oldest`, `sender` or `subject`, the four orders of the thread list in the app. `sender` and `subject` are alphabetical, newest first within one sender or subject. - `date_from` (`Time, DateTime or String`): Keeps threads whose newest message arrived at or after this instant. A `Time`, a `DateTime` or an ISO 8601 string with a time and an offset. - `date_to` (`Time, DateTime or String`): Keeps threads whose newest message arrived at or before this instant. Both ends are included, and `date_from:` after `date_to:` is a 422. - `from_contacts` (`Boolean`): When true, keeps only threads whose newest message came from a saved contact. A key limited to some addresses reads the contacts its owner saved. - `limit` (`Integer`): Page size for each request, a whole number from 1 to 100. Defaults to 25. - `cursor` (`String`): A `next_cursor` to start the walk from instead of the first page. - `api_key` (`String`): Overrides the client's API key for every page of this walk. **Returns** An Array of Hashes, every matching thread with `object` set to `thread` and its `id`, newest first. **Example** ```ruby snoozed = client.threads.list_all(folder: "snoozed", limit: 100) puts "#{snoozed.size} threads are waiting to wake" ``` **Notes** - Each page is its own request with its own retries, so a network blip on page five does not restart the walk from page one. - Rows are ids only. Reading the threads afterwards is one `get` per id. Also available in: API [`GET /threads`](https://openemail.uk/docs/api/reference/threads#get-threads); TypeScript [`threads.listAll()`](https://openemail.uk/docs/sdk/reference/threads#listAll); Python [`threads.list_all()`](https://openemail.uk/docs/python/reference/threads#listAll). ### `threads.iterate` Stream threads one at a time across pages ```ruby iterate(folder: nil, query: nil, label_ids: nil, sort: nil, date_from: nil, date_to: nil, from_contacts: nil, limit: nil, cursor: nil, api_key: nil, &block) -> Enumerator ``` Returns an Enumerator that yields threads one by one, or yields each one to a block when given one, and requests the next page only when the current one is used up. Nothing is fetched until the loop starts, and breaking out of it stops further requests, so this is the way to scan a large folder for the first match. Filters behave as in `list`, and each request asks for `limit:` threads, 25 by default. The cursor marks a position in time rather than a row count, so trashing, archiving or relabelling threads inside the loop does not make the walk skip the ones after them. A thread that receives new mail during the walk moves ahead of the cursor and is not yielded again. Scopes: `threads:read`. **Parameters** - `folder` (`String`): Label the threads must carry, case insensitive. Defaults to `inbox`. - `query` (`String`): Mailbox search, as in `list`. Plain words must all appear and match loosely, a quoted phrase has to appear as written, filler words are dropped when something else is left to search for, and operators such as `from:ada`, `has:pdf` and `in:anywhere` narrow it. - `label_ids` (`String or Array`): Label ids a thread must all carry on top of `folder:`, matched exactly. - `sort` (`String`): `newest` (the default), `oldest`, `sender` or `subject`, the four orders of the thread list in the app. `sender` and `subject` are alphabetical, newest first within one sender or subject. - `date_from` (`Time, DateTime or String`): Keeps threads whose newest message arrived at or after this instant. A `Time`, a `DateTime` or an ISO 8601 string with a time and an offset. - `date_to` (`Time, DateTime or String`): Keeps threads whose newest message arrived at or before this instant. Both ends are included, and `date_from:` after `date_to:` is a 422. - `from_contacts` (`Boolean`): When true, keeps only threads whose newest message came from a saved contact. A key limited to some addresses reads the contacts its owner saved. - `limit` (`Integer`): Page size for each request, a whole number from 1 to 100. Defaults to 25. - `cursor` (`String`): A `next_cursor` to start from instead of the first page. - `api_key` (`String`): Overrides the client's API key for every page of this walk. **Returns** An Enumerator of Hashes, each with `object` set to `thread` and `id`, or yields each one to a block. **Example** ```ruby client.threads.iterate(folder: "inbox", query: "receipt newer_than:30d", limit: 100) do |summary| thread = client.threads.get(summary[:id]) client.threads.update(summary[:id], read: true) if thread[:hasUnread] end ``` **Notes** - The Enumerator is lazy, so an abandoned loop costs only the pages it consumed. Also available in: API [`GET /threads`](https://openemail.uk/docs/api/reference/threads#get-threads); TypeScript [`threads.iterate()`](https://openemail.uk/docs/sdk/reference/threads#iterate); Python [`threads.iterate()`](https://openemail.uk/docs/python/reference/threads#iterate). ### `threads.get` Read a thread with every message on it ```ruby get(id, api_key: nil) -> Hash ``` Returns the whole conversation, oldest message first, with the labels the thread sits in and its unread state. Unsent draft replies are included in `messages` with `isDraft: true`, which is why `messageCount`, the length of `messages`, can be higher than `totalReplies`, which counts only real messages. Messages are passed through as the mailbox stored them, so each message is an open Hash rather than a fixed field list. The one field the API commits to is `encryption`. When `encryption.format` is `pgp-mime`, `pgp-inline` or `smime-encrypted`, the message is sealed and its body is empty or holds armour. `pgp-signed` and `smime-signed` are ordinary readable mail. A message with no `encryption` at all was stored before detection existed, so its absence says nothing about whether it was plaintext. Each message's `tags` and `unread` are overwritten on read with the thread's current labels and unread flag, so they describe the thread and not that one message. Scopes: `threads:read`. **Parameters** - `id` (`String`, required): Thread id, as returned by `list` or carried on a message. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `id` echoed from the request, `messages`, `labels` as Hashes with `id`, `name` and `color`, `messageCount`, `hasUnread`, `totalReplies` and `deliveredTo`, the workspace address the thread belongs to (nil when none was recorded). **Example** ```ruby thread = client.threads.get("CAHk7pQ2x9LmZ4-mail.example.com") thread[:messages].each do |message| state = OpenEmail.sealed?(message) ? "sealed" : "readable" puts "#{message[:id]} #{message[:subject]} #{state}" end label_ids = thread[:labels].map { |label| label[:id] } p label_ids ``` **Notes** - A thread delivered to no address the key covers is a 404, exactly like one that does not exist. - `hasUnread` mirrors the `UNREAD` label, and `update` with `read` is how you change it. - Draft ids from `drafts.list` open here too, because a draft is stored as a thread labelled `DRAFT`. Also available in: API [`GET /threads/{id}`](https://openemail.uk/docs/api/reference/threads#get-threads-id); TypeScript [`threads.get()`](https://openemail.uk/docs/sdk/reference/threads#get); Python [`threads.get()`](https://openemail.uk/docs/python/reference/threads#get); CLI [`openemail threads get`](https://openemail.uk/docs/cli/reference/threads#threads-get). ### `threads.update` Mark a thread read or unread and change its labels ```ruby update(id, patch = nil, api_key: nil, **fields) -> Hash ``` Adds and removes labels on a thread in one call. `read` is shorthand for the `UNREAD` label: `true` removes it and `false` adds it. At least one of `read`, a non empty `addLabelIds` or a non empty `removeLabelIds` is required, each list takes at most 50 ids, and any other key is a 422 because the body is strict. Folders are labels too, so archiving is `addLabelIds: ["ARCHIVE"]` with `removeLabelIds: ["INBOX"]`, the same pair the app uses. `TRASH`, `SNOOZED` and `DRAFT` are refused in either list with 422 `label_not_directly_settable`, because each needs a step this route cannot take. Use `trash` and `snooze` for those. User label ids come from `labels.list`, and the system ids such as `ARCHIVE`, `STARRED` and `UNREAD` are taken in any case. An id in `addLabelIds` that names no label is refused with 422 `label_not_found` and nothing on the thread changes, so create the label with `labels.create` first. An unknown id in `removeLabelIds` is not an error, since the thread cannot carry it. Removals are applied before additions, so an id in both lists ends up on the thread. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `read` (`Boolean`): `true` removes `UNREAD`, `false` adds it. - `addLabelIds` (`Array`): Label ids to put on the thread, at most 50, each naming a label, never `TRASH`, `SNOOZED` or `DRAFT`. - `removeLabelIds` (`Array`): Label ids to take off the thread, at most 50, never `TRASH`, `SNOOZED` or `DRAFT`. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `id`, `addedLabelIds` and `removedLabelIds`. Both lists echo the request, with system ids upper cased, plus the `UNREAD` change that `read` implies, not what actually changed. **Example** ```ruby updated = client.threads.update( "CAHk7pQ2x9LmZ4-mail.example.com", read: true, addLabelIds: ["ARCHIVE", "USER_RECEIPTS"], removeLabelIds: ["INBOX"] ) p updated[:addedLabelIds], updated[:removedLabelIds] ``` **Notes** - The SDK retries this call after a network failure or a retryable status, which is safe because adding a label already present or removing one already gone changes nothing. - The thread is looked up before the body is validated, so a wrong id is a 404 even when the patch is also invalid. - User label ids look like `USER_RECEIPTS`. Take them from `labels.list` rather than building them. Also available in: API [`PATCH /threads/{id}`](https://openemail.uk/docs/api/reference/threads#patch-threads-id); TypeScript [`threads.update()`](https://openemail.uk/docs/sdk/reference/threads#update); Python [`threads.update()`](https://openemail.uk/docs/python/reference/threads#update); CLI [`openemail threads update`](https://openemail.uk/docs/cli/reference/threads#threads-update). ### `threads.trash` Move a thread to the Bin ```ruby trash(id, api_key: nil) -> Hash ``` Adds `TRASH` and removes `INBOX`, `SPAM`, `SNOOZED` and `ARCHIVE` in one step, which is what the app's delete does. Doing half of that through `update` would leave the thread listed in both the Bin and its old folder, which is why `update` refuses `TRASH`. Nothing is deleted. The thread stays readable with `get` and lists under `folder: "trash"`. Calling this on a thread that is already in the Bin changes nothing and returns the same body, which is why the SDK retries it. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `object` set to `thread`, `id` and `trashed` set to true. **Example** ```ruby result = client.threads.trash("CAHk7pQ2x9LmZ4-mail.example.com") puts result[:id], result[:trashed] ``` **Notes** - `restore` takes a thread back out of the Bin. `update` refuses `TRASH` in `removeLabelIds` as well as in `addLabelIds`. - Trashing a snoozed thread also cancels its scheduled wake, so it does not reappear in the inbox later. - A thread delivered to no address the key covers is a 404. Also available in: API [`POST /threads/{id}/trash`](https://openemail.uk/docs/api/reference/threads#post-threads-id-trash); TypeScript [`threads.trash()`](https://openemail.uk/docs/sdk/reference/threads#trash); Python [`threads.trash()`](https://openemail.uk/docs/python/reference/threads#trash); CLI [`openemail threads trash`](https://openemail.uk/docs/cli/reference/threads#threads-trash). ### `threads.snooze` Hide a thread until a set time ```ruby snooze(id, wake_at, api_key: nil) -> Hash ``` Adds `SNOOZED`, removes `INBOX` and stores a wake time, all in one call. Both halves matter: the label hides the thread and the stored wake time is what brings it back. A thread labelled `SNOOZED` any other way would never return, which is why `update` refuses that label. `wake_at` takes a `Time`, a `DateTime` or an ISO 8601 string. The SDK sends a `Time` or a `DateTime` as a UTC ISO 8601 instant, and the server answers 422 `invalid_parameter` on `wakeAt` when the value does not parse or is not in the future. Snoozing a thread that is already snoozed replaces its wake time. Threads are woken by an hourly sweep, so one comes back at the first sweep after `wake_at`, up to about an hour late. Opening the Snoozed folder in the app wakes overdue threads straight away. A thread always wakes into the inbox. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `wake_at` (`Time, DateTime or String`, required): When the thread should return, a future instant. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `id` and `snoozedUntil`, the wake time normalised to a UTC ISO 8601 string. **Example** ```ruby tomorrow = Time.now.utc + 86_400 wake_at = Time.utc(tomorrow.year, tomorrow.month, tomorrow.day, 9) snoozed = client.threads.snooze("CAHk7pQ2x9LmZ4-mail.example.com", wake_at) puts snoozed[:snoozedUntil] ``` **Notes** - Only `INBOX` is removed, so a thread snoozed from another folder keeps that folder's label while it sleeps and wakes carrying both. - A string with no zone offset is read in the server's local zone, so send `Z` or an explicit offset. - The SDK retries this call, which is safe because a repeat stores the same wake time. Also available in: API [`POST /threads/{id}/snooze`](https://openemail.uk/docs/api/reference/threads#post-threads-id-snooze); TypeScript [`threads.snooze()`](https://openemail.uk/docs/sdk/reference/threads#snooze); Python [`threads.snooze()`](https://openemail.uk/docs/python/reference/threads#snooze); CLI [`openemail threads snooze`](https://openemail.uk/docs/cli/reference/threads#threads-snooze). ### `threads.unsnooze` Bring a snoozed thread back now ```ruby unsnooze(id, api_key: nil) -> Hash ``` Adds `INBOX`, removes `SNOOZED` and deletes the stored wake time, so the thread returns immediately and the hourly sweep leaves it alone afterwards. A thread that is not snoozed is left where it is, so an archived thread stays archived, and the response still reports `snoozedUntil` as nil. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `id` and `snoozedUntil` set to nil. **Example** ```ruby result = client.threads.unsnooze("CAHk7pQ2x9LmZ4-mail.example.com") p result[:snoozedUntil] ``` **Notes** - Removing `SNOOZED` through `update` is refused with 422 `label_not_directly_settable`, because it would leave the wake time scheduled. - Safe to retry, and the SDK does: a second call applies the same labels and deletes a wake time that is already gone. Also available in: API [`POST /threads/{id}/unsnooze`](https://openemail.uk/docs/api/reference/threads#post-threads-id-unsnooze); TypeScript [`threads.unsnooze()`](https://openemail.uk/docs/sdk/reference/threads#unsnooze); Python [`threads.unsnooze()`](https://openemail.uk/docs/python/reference/threads#unsnooze); CLI [`openemail threads unsnooze`](https://openemail.uk/docs/cli/reference/threads#threads-unsnooze). ### `threads.list_attachments` List a message's attachments with their content ```ruby list_attachments(id, message_id, api_key: nil) -> Array ``` Returns the attachments of one message with each file's bytes inlined as base64 in `content`. The thread is checked first and then the message, so a `message_id` that is not on that thread is a 404 even when it exists elsewhere in the mailbox. Take message ids from the `messages` of `threads.get`. This is the display list. The ciphertext of an encrypted envelope is in it and downloads like any other file, named `encrypted-message.asc` when it arrived without a name. The PGP/MIME version part and any detached signature are held out on purpose. Every part keeps its id in the message's `encryption.parts`, and for those two the id is a correlation key only: no route returns their bytes. Every file comes back whole in a single response, with no size cap and no range reads, so a message carrying large files makes a large response. Scopes: `threads:read`. **Parameters** - `id` (`String`, required): Thread id the message belongs to. - `message_id` (`String`, required): Message id from that thread's `messages`. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** An Array of Hashes, each with `attachmentId`, `filename`, `contentType`, `size` and base64 `content`. **Example** ```ruby files = client.threads.list_attachments("CAHk7pQ2x9LmZ4-mail.example.com", "message_4c1b257a") files.each do |file| bytes = file[:content].to_s.unpack1("m") puts "#{file[:filename]} #{file[:contentType]} #{bytes.bytesize}" end ``` **Notes** - When the stored bytes for a file cannot be found, `content` is an empty string rather than nil, so check its length before decoding. - Both ids must match: a real message id paired with the wrong thread id is a 404 `resource_not_found`. - A thread delivered to no address the key covers is a 404 before the message is looked at. Also available in: API [`GET /threads/{id}/messages/{messageId}/attachments`](https://openemail.uk/docs/api/reference/threads#get-threads-id-messages-messageid-attachments); TypeScript [`threads.listAttachments()`](https://openemail.uk/docs/sdk/reference/threads#listAttachments); Python [`threads.list_attachments()`](https://openemail.uk/docs/python/reference/threads#listAttachments); CLI [`openemail threads list-attachments`](https://openemail.uk/docs/cli/reference/threads#threads-list-attachments). ### `threads.list_notes` List the notes on a thread ```ruby list_notes(id, api_key: nil) -> Array ``` Returns every note on one thread, the Notes panel of the reading pane: pinned notes first, then the rest in the order they were arranged. Notes are private to a person. A key reads and writes the notes of the workspace owner, and an app those of the person who connected it. A key limited to particular addresses reaches only the notes on threads that arrived at them. Scopes: `threads:read`. **Parameters** - `id` (`String`, required): Thread id. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** An Array of Hashes, each with `id`, `threadId`, `content`, `color`, `pinned`, `order`, `createdAt` and `updatedAt`. **Example** ```ruby notes = client.threads.list_notes("CAHk7pQ2x9LmZ4-mail.example.com") notes.each do |note| puts note[:pinned] ? "pinned #{note[:content]}" : note[:content] end ``` **Notes** - A thread delivered to no address the key covers is a 404. Also available in: API [`GET /threads/{id}/notes`](https://openemail.uk/docs/api/reference/notes#get-threads-id-notes); TypeScript [`threads.listNotes()`](https://openemail.uk/docs/sdk/reference/threads#listNotes); Python [`threads.list_notes()`](https://openemail.uk/docs/python/reference/threads#listNotes); CLI [`openemail threads list-notes`](https://openemail.uk/docs/cli/reference/threads#threads-list-notes). ### `threads.create_note` Add a note to a thread ```ruby create_note(id, body = nil, api_key: nil, **fields) -> Hash ``` Pins a private note to a thread, as the Notes panel does. A new note goes after the others, and `pinned` keeps it at the top. Notes are private to a person. A key reads and writes the notes of the workspace owner, and an app those of the person who connected it. A key limited to particular addresses reaches only the notes on threads that arrived at them. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `content` (`String`, required): The text of the note, up to 20,000 characters. Leading and trailing spaces are trimmed. - `color` (`String`): One of the eight the app offers: `default`, `red`, `orange`, `yellow`, `green`, `blue`, `purple` or `pink`. Defaults to `default`. - `pinned` (`Boolean`): Keeps the note above the others. Defaults to false. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash for the new note, with the fields `list_notes` returns. **Example** ```ruby note = client.threads.create_note( "CAHk7pQ2x9LmZ4-mail.example.com", content: "Waiting on the signed contract before replying.", color: "yellow", pinned: true ) puts note[:id] ``` **Notes** - The SDK does not retry it, because a second call would add a second note. Also available in: API [`POST /threads/{id}/notes`](https://openemail.uk/docs/api/reference/notes#post-threads-id-notes); TypeScript [`threads.createNote()`](https://openemail.uk/docs/sdk/reference/threads#createNote); Python [`threads.create_note()`](https://openemail.uk/docs/python/reference/threads#createNote); CLI [`openemail threads create-note`](https://openemail.uk/docs/cli/reference/threads#threads-create-note). ### `threads.update_note` Change a note ```ruby update_note(id, note_id, patch = nil, api_key: nil, **fields) -> Hash ``` Changes the text of a note, its colour or whether it is pinned. Give at least one of the three. A note id that is not on this thread is a 404, even when the note exists on another thread. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `note_id` (`String`, required): The note's id, from `list_notes`. - `content` (`String`): The new text, up to 20,000 characters. - `color` (`String`): The new colour. - `pinned` (`Boolean`): Pins or unpins it. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash for the note as it is now, with the fields `list_notes` returns. **Example** ```ruby note = client.threads.update_note("CAHk7pQ2x9LmZ4-mail.example.com", "b3d1f0c2-7a4e-4f7b-9c1d-2e8f6a5b4c3d", pinned: false) p note[:pinned] ``` **Notes** - Safe to repeat: setting the same values twice leaves the note as it was. Also available in: API [`PATCH /threads/{id}/notes/{noteId}`](https://openemail.uk/docs/api/reference/notes#patch-threads-id-notes-noteid); TypeScript [`threads.updateNote()`](https://openemail.uk/docs/sdk/reference/threads#updateNote); Python [`threads.update_note()`](https://openemail.uk/docs/python/reference/threads#updateNote); CLI [`openemail threads update-note`](https://openemail.uk/docs/cli/reference/threads#threads-update-note). ### `threads.delete_note` Delete a note ```ruby delete_note(id, note_id, api_key: nil) -> Hash ``` Deletes a note for good. There is no bin for notes. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `note_id` (`String`, required): The note's id, from `list_notes`. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `object` set to `note`, `id`, `threadId` and `deleted` set to true. **Example** ```ruby client.threads.delete_note("CAHk7pQ2x9LmZ4-mail.example.com", "b3d1f0c2-7a4e-4f7b-9c1d-2e8f6a5b4c3d") ``` **Notes** - The SDK does not retry a delete. A 404 on your own second attempt after a lost response means the first one worked. Also available in: API [`DELETE /threads/{id}/notes/{noteId}`](https://openemail.uk/docs/api/reference/notes#delete-threads-id-notes-noteid); TypeScript [`threads.deleteNote()`](https://openemail.uk/docs/sdk/reference/threads#deleteNote); Python [`threads.delete_note()`](https://openemail.uk/docs/python/reference/threads#deleteNote); CLI [`openemail threads delete-note`](https://openemail.uk/docs/cli/reference/threads#threads-delete-note). ### `threads.reorder_notes` Arrange the notes on a thread ```ruby reorder_notes(id, ids, api_key: nil) -> Array ``` Sets the order of every note on a thread at once, first to last, as dragging them in the Notes panel does. Pinned notes still come first. `ids` has to name every note on the thread exactly once. Anything else is a 422 `invalid_parameter` on `ids`, and nothing moves. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `ids` (`Array`, required): Every note id on the thread, in the order you want them. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** An Array of note Hashes in the new order. **Example** ```ruby notes = client.threads.list_notes("CAHk7pQ2x9LmZ4-mail.example.com") reversed = notes.map { |note| note[:id] }.reverse client.threads.reorder_notes("CAHk7pQ2x9LmZ4-mail.example.com", reversed) ``` **Notes** - Safe to repeat: the same order twice leaves the notes as they were. Also available in: API [`POST /threads/{id}/notes/reorder`](https://openemail.uk/docs/api/reference/notes#post-threads-id-notes-reorder); TypeScript [`threads.reorderNotes()`](https://openemail.uk/docs/sdk/reference/threads#reorderNotes); Python [`threads.reorder_notes()`](https://openemail.uk/docs/python/reference/threads#reorderNotes); CLI [`openemail threads reorder-notes`](https://openemail.uk/docs/cli/reference/threads#threads-reorder-notes). ### `threads.counts` Count the mail in each folder ```ruby counts(address: nil, api_key: nil) -> Hash ``` Returns what the sidebar of the app shows: how many conversations each folder holds and how many of them are unread, and how many inbox conversations arrived at each address of the workspace. `folders` has one row per folder, named by its label id in lower case: `inbox`, `sent`, `spam`, `archive`, `trash` and `snoozed`, then `unread`, whose `count` is the unread conversations in the inbox. `addresses` counts the inbox per address the mail was delivered to, with nil for mail that recorded none. A key limited to particular addresses counts only the mail that arrived at them. `address:` narrows every count to one address, and one the key does not reach counts nothing rather than failing. Scopes: `threads:read`. **Parameters** - `address` (`String`): Count only the mail delivered to this address. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `object` set to `mailbox_counts`, `folders` and `addresses`. Each folder is a Hash with `label`, `count` and `unread`, and each address a Hash with `address` and `count`. **Example** ```ruby counts = client.threads.counts inbox = counts[:folders].find { |folder| folder[:label] == "inbox" } || {} puts "#{inbox.fetch(:unread, 0)} unread of #{inbox.fetch(:count, 0)}" counts[:addresses].each do |row| puts "#{row[:address] || "(none)"} #{row[:count]}" end ``` **Notes** - Read only, so the SDK retries it after a network failure like any other read. Also available in: API [`GET /threads/counts`](https://openemail.uk/docs/api/reference/threads#get-threads-counts); TypeScript [`threads.counts()`](https://openemail.uk/docs/sdk/reference/threads#counts); Python [`threads.counts()`](https://openemail.uk/docs/python/reference/threads#counts); CLI [`openemail threads counts`](https://openemail.uk/docs/cli/reference/threads#threads-counts). ### `threads.summary` Read the summary of a thread ```ruby summary(id, api_key: nil) -> Hash ``` Returns the short AI summary the reading pane shows above a thread. A summary is written once and kept, and written again when a new message arrives, so reading one is cheap. `state` is `ready` with the text in `summary`, `pending` while one is being written, or `none` when there is nothing to summarise, such as a thread holding a message that arrived encrypted, whose body OpenEmail never reads. A `pending` answer starts the writing, so ask again a few seconds later. Scopes: `threads:read`. **Parameters** - `id` (`String`, required): Thread id. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `object` set to `thread_summary`, `threadId`, `state` and `summary`, with `summary` nil unless `state` is `ready`. **Example** ```ruby result = client.threads.summary("CAHk7pQ2x9LmZ4-mail.example.com") if result[:state] == "pending" puts "Being written, ask again in a few seconds" else puts result[:summary] || result[:state] end ``` **Notes** - Writing a summary spends one of the workspace's AI actions. Reading one that is already written spends nothing. - A thread delivered to no address the key covers is a 404. Also available in: API [`GET /threads/{id}/summary`](https://openemail.uk/docs/api/reference/threads#get-threads-id-summary); TypeScript [`threads.summary()`](https://openemail.uk/docs/sdk/reference/threads#summary); Python [`threads.summary()`](https://openemail.uk/docs/python/reference/threads#summary); CLI [`openemail threads summary`](https://openemail.uk/docs/cli/reference/threads#threads-summary). ### `threads.restore` Take a thread out of the Bin ```ruby restore(id, api_key: nil) -> Hash ``` Puts a thread back in the inbox, out of the Bin and out of Spam, which is what Restore from Bin and Move to inbox do in the app. It is the undo of `trash`. Calling it on a thread that is already in the inbox changes nothing and returns the same body, which is why the SDK retries it. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `object` set to `thread`, `id` and `restored` set to true. **Example** ```ruby client.threads.trash("CAHk7pQ2x9LmZ4-mail.example.com") restored = client.threads.restore("CAHk7pQ2x9LmZ4-mail.example.com") p restored[:restored] ``` **Notes** - A thread that was archived before it went to the Bin comes back to the inbox, not to the archive. - A thread delivered to no address the key covers is a 404. Also available in: API [`POST /threads/{id}/restore`](https://openemail.uk/docs/api/reference/threads#post-threads-id-restore); TypeScript [`threads.restore()`](https://openemail.uk/docs/sdk/reference/threads#restore); Python [`threads.restore()`](https://openemail.uk/docs/python/reference/threads#restore); CLI [`openemail threads restore`](https://openemail.uk/docs/cli/reference/threads#threads-restore). ### `threads.delete` Delete a thread for good ```ruby delete(id, api_key: nil) -> Hash ``` Deletes every message in a thread, with its attachments, which is what Delete from Bin does in the app. It cannot be undone. It works on a thread in any folder, so call `trash` instead when you only mean to discard the thread: a trashed thread stays readable and `restore` brings it back. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `object` set to `thread`, `id` and `deleted` set to true. **Example** ```ruby client.threads.delete("CAHk7pQ2x9LmZ4-mail.example.com") ``` **Notes** - The SDK does not retry a delete. A 404 on your own second attempt after a lost response means the first one worked. - A 500 `thread_delete_failed` means nothing was removed, so the call is safe to repeat. - A thread delivered to no address the key covers is a 404. Also available in: API [`DELETE /threads/{id}`](https://openemail.uk/docs/api/reference/threads#delete-threads-id); TypeScript [`threads.delete()`](https://openemail.uk/docs/sdk/reference/threads#delete); Python [`threads.delete()`](https://openemail.uk/docs/python/reference/threads#delete); CLI [`openemail threads delete`](https://openemail.uk/docs/cli/reference/threads#threads-delete). ### `threads.unsubscribe` Unsubscribe from the sender of a thread ```ruby unsubscribe(id, api_key: nil) -> Hash ``` Does what the Unsubscribe button of the reading pane does: finds the subscription behind the newest message of the thread that carries a `List-Unsubscribe` header and unsubscribes from it the way the sender asks for, with a one-click request or an unsubscribe email. A sender that only offers a page cannot be unsubscribed by a program, so `method` is `link` and `url` is the page a person has to open. A thread with no unsubscribe header is a 422 `unsubscribe_unsupported`, and a thread delivered to no address the key covers is a 404. Scopes: `threads:write`. **Parameters** - `id` (`String`, required): Thread id. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash with `object` set to `unsubscribe`, `threadId`, `subscriptionId`, `method`, `url` and `binned`. **Example** ```ruby result = client.threads.unsubscribe("CAHk7pQ2x9LmZ4-mail.example.com") puts result[:method] ``` **Notes** - The SDK does not retry it, because a second call can send a second unsubscribe email. Also available in: API [`POST /threads/{id}/unsubscribe`](https://openemail.uk/docs/api/reference/subscriptions#post-threads-id-unsubscribe); TypeScript [`threads.unsubscribe()`](https://openemail.uk/docs/sdk/reference/threads#unsubscribe); Python [`threads.unsubscribe()`](https://openemail.uk/docs/python/reference/threads#unsubscribe); CLI [`openemail threads unsubscribe`](https://openemail.uk/docs/cli/reference/threads#threads-unsubscribe). ### `threads.get_event` Read the event a thread carries ```ruby get_event(id, api_key: nil) -> Hash ``` Returns the calendar event that came with an invitation in the thread, as the invitation card of the reading pane shows it. Answer it with `calendar.respond_to_event`. Scopes: `calendar:read`. **Parameters** - `id` (`String`, required): Thread id, as `threads.list` returns it. - `api_key` (`String`): Overrides the client's API key for this call only. **Returns** A Hash, the event as `calendar.get_event` returns it. **Example** ```ruby event = client.threads.get_event("thr_6d1a9c4e2b7f30d85e1c4a92") puts event[:summary], event[:start] ``` **Notes** - A thread with no event, or one the key does not reach, is a 404. Also available in: API [`GET /threads/{id}/event`](https://openemail.uk/docs/api/reference/calendar#get-threads-id-event); TypeScript [`threads.getEvent()`](https://openemail.uk/docs/sdk/reference/threads#getEvent); Python [`threads.get_event()`](https://openemail.uk/docs/python/reference/threads#getEvent); CLI [`openemail threads get-event`](https://openemail.uk/docs/cli/reference/threads#threads-get-event).
