Каждая операция этой группы: что она принимает, что возвращает и какими ошибками может ответить.

Операции

A body authored once and sent many times, scoped to the workspace rather than to whoever wrote it.

Two engines, for two different people. blocks is a validated tree whose node kinds are the exports of @react-email/components, checked at its input and rendered here. html is markup you rendered yourself (a react-email component run through @react-email/render in your own build, a design-tool export, a hand-written table layout), sanitised once when the version is published. We cannot execute your JSX: workerd has no eval and no transpiler, so the render happens where the component lives and what crosses the wire is HTML.

Versions are immutable once published, and that is the feature rather than bookkeeping. Editing a published template mints a new draft; live sends keep resolving the frozen version until somebody publishes again. Without it, renaming a slot in the editor would silently start sending mail with a blank where the order number was: no error, nothing in a log, and no way to recall it. With it, the published version keeps saying orderId and the caller finds out from a 422 on their own schedule.

POST /emails also takes a template field, so a caller already composing a message need not switch endpoints to reach a stored body.

GET/templates

List templates

Разрешенияtemplates:readЧитает

Each row carries the PUBLISHED version's subject, engine, slots and props, so a caller can see what to pass a template without a request per row. A template with nothing published carries none of them and reports publishedVersion: null.

Requires the templates:read scope.

Параметры запроса

limitinteger

Defaults to 25. The bound lives in the service, so it is not in the schema.

Не меньше 1Не больше 100
cursorstring

The nextCursor you were handed, passed back as it came and never one you build. It is opaque: it holds the sort it was handed out under and where the last template sat in that order, so a template deleted between pages never breaks the walk. Keyset on whichever sort you asked for, so a template edited mid-pagination under the default sort moves to the front and can be seen twice. A value this list did not hand out, or one handed out under another sort, is a 400 invalid_cursor.

От 1 до 2048 символов
statusstring

Narrows to drafts, active or archived templates. Omit for all three. draft here is the template's own status, not "has an unpublished draft", which every template has.

Одно из"draft""active""archived"
searchstring

Matches the name, the slug, the description, the published version's subject and the id. Every word has to appear, and each matches loosely: case, accents and separators are ignored and part of a longer word counts. When nothing matches exactly, close spellings are returned instead. % and _ are taken literally rather than as wildcards, so pasting a name in cannot turn into a scan.

До 200 символов
sortstring

The order, and the field the cursor keys on. updated-newest is the default and the one the console lists under. Keep it the same while you page, because a cursor handed out under one sort is refused under another.

Одно из"updated-newest""updated-oldest""created-newest""created-oldest""name""name-reversed"

Возвращает

A page, most recently updated first.

POST/templates

Create a template

Разрешенияtemplates:writeИзменяет данные

Creates the template and its version 1. publish: true freezes that version there and then; without it you get a DRAFT, and a draft is not sendable. POST /templates/{id}/send answers template_not_published until somebody publishes it.

The engine follows what you send: html when you post html, blocks otherwise, and engine is only worth stating to be explicit about it. document, slots and props are unconstrained in this schema on purpose. One validator owns the block tree so that REST, tRPC and MCP cannot each hold a slightly different copy of it, and a bad node comes back as a 422 naming its path rather than as a schema error here.

Requires the templates:write scope.

The body of a blocks template: the block tree plus the page settings wrapped around it. An html template has none of this and carries html instead.

It REPLACES wholesale. A PATCH that sends document sends the whole document, so a call that rebuilds body and omits fonts drops the fonts. Read the head with GET /templates/{id} (or an older revision with GET /templates/{id}/versions/{version}), change what you mean to change, and post the result back.

GET/templates/fonts

List the web fonts a template can load

Разрешенияtemplates:readЧитает

A template loads a web font by naming a family and the url it is served from, and 17 families are accepted: DM Sans, Inter, Roboto, Open Sans, Lato, Montserrat, Poppins, Nunito, Work Sans, Source Sans 3, IBM Plex Sans, Merriweather, Playfair Display, Instrument Serif, JetBrains Mono, DM Mono, Geist Mono. This is that list, with the exact url each one takes.

The list is closed on purpose. A font file is fetched by the reader's mail client the moment the message is opened, so a url pointing anywhere else would report opens to whoever runs that host, silently and regardless of what the workspace has open tracking set to. A webFont.url that is not the one this endpoint gives for its family is a 422 invalid_template naming the font.

One template may load 8 of them. A font whose family is not here still renders: leave webFont out and the family falls back to fallbackFontFamily, which is what Gmail and Outlook on Windows do with every web font anyway.

Static, not workspace data, so the same answer comes back for every key.

Requires the templates:read scope.

GET/templates/starters

List the starter designs

Разрешенияtemplates:readЧитает

The same catalogue the console offers when somebody starts a template, so an integration and a person begin from the same designs rather than from two divergent lists.

Not paginated and not workspace data: these ship with the product. The slug is what POST /templates takes as starter and what POST /templates/{id}/content takes to re-skin an existing template. Bodies and previews are on the single retrieval, because twenty rendered emails is not a list payload.

Requires the templates:read scope.

Adds the two heavy fields: document, the block tree, and preview, the starter rendered with its placeholders left visible.

POST/templates/render

Render a body that is not stored

Разрешенияtemplates:readЧитает

Compiles content you pass in and hands back what a message built from it would carry. No template is created, none is read, and nothing is sent. It is what the web editor calls while somebody types, and the way to check a design in CI before it becomes a template at all.

It takes exactly what a create takes as content, plus values for the placeholders. Lenient like a preview: an unfilled key comes back in warnings rather than refusing, because a body being rendered is usually a body being written. mark: true leaves every placeholder as {{key}}, which is how an editor shows an author what is a variable.

Needs only templates:read, since nothing is written, and it is the one templates path that names no template.

Requires the templates:read scope.

Разрешенияtemplates:readЧитает

latest is the head (the current draft, or the published version when nothing has been edited since), and it is the only place document and html are returned in full. The template's own subject, engine, slots and props still describe the PUBLISHED version, which is what a send would use, so the two disagree exactly while somebody is mid-edit.

PATCH/templates/{id}

Update a template

Разрешенияtemplates:writeИзменяет данные

Metadata (name, description, status) changes the template in place. Anything touching the body (subject, document, html, slots, props, engine) writes into the DRAFT, and mints version N+1 when the head is already published. Nothing here changes what a live send resolves to: that only moves when somebody publishes.

expectedVersion is the version you read before editing. Supply it and a concurrent edit is a 409 instead of a silent overwrite, which is what an automated writer wants; omit it and the last write wins, which is fine for one person in one tab.

POST/templates/{id}/duplicate

Copy a template

Разрешенияtemplates:writeИзменяет данные

Creates a separate template from the HEAD of this one: same subject, body, slots, props and description, at version 1 and always a DRAFT, whatever the source had published. A copy is therefore never sendable by accident.

Nothing links the copy to the source afterwards, which is what makes this the safe way to try a redesign of a template that is sending in production.

name is optional. Left out, the source name is reused, and since a name is unique per workspace the server appends a number until one is free, up to twenty. A name you send that is taken is treated the same way, so a nightly copy keeps working rather than failing on the second run.

POST/templates/{id}/content

Replace the design

Разрешенияtemplates:writeУдаляет

Swaps the whole body for a starter design or for another template's, keeping this template's identity: the id, slug, name, description and status do not move, and neither does what a live send resolves to.

The write lands where a body edit lands. A draft head is overwritten in place; a published head mints version N+1 as a draft. Sends keep using the published version until somebody publishes, which is what makes this safe to call on a template that is sending.

Name exactly one source. starter takes a slug from GET /templates/starters; fromTemplateId takes another template in this workspace, whose published version is copied when it has one and whose draft is copied otherwise. A source in another workspace is a 404 like anything else, and the template naming itself is a 422.

The new body brings the source's slots and props with it and replaces the declarations wholesale, so a send that passed the old props can start being refused. Read the response before publishing.

Derived from the name when the template is created and never re-derived on rename, so retitling "Order shipped" to "Dispatch confirmation" cannot 404 an integration that has been sending against it. This is the handle to pin in code; every path taking an {id} takes it too.

GET/templates/{id}/versions

List versions

Разрешенияtemplates:readЧитает

Bodies are omitted here. document and html come back on a retrieval or a publish, because a list of twenty block trees is a payload nobody asked for. What each version DECLARES (slots, props, subject) is present, which is what makes this the endpoint for "what would pinning version 3 commit me to".

To read one old body, GET the version itself at /templates/{id}/versions/{version}. That is the call for a diff against today's draft, and it does not disturb the head the way a restore does.

Requires the templates:read scope.

idstringОбязательно

The previous page's nextCursor, passed back as it came. It is opaque: it holds where the last row sat in this list's order, so a row deleted or edited between pages never breaks the walk, and the next page starts at the first row that sorts after it. A value this list did not hand out is a 400 invalid_cursor.

Возвращает

A page of versions, newest first. Every publish adds one, so follow nextCursor while hasMore is true to reach version 1. Keyset on the version number, so a version deleted between pages never breaks the walk.

POST/templates/{id}/versions

Publish the draft

Разрешенияtemplates:writeИзменяет данные

A POST to the version COLLECTION, because that is what it creates: a frozen revision that live sends resolve against. Compiling happens here, so a template that does not render fails for the person publishing it rather than for the recipient of the next message.

Idempotent: publishing an already-published head returns it unchanged, so a deploy script that publishes unconditionally is safe to run twice.

Requires the templates:write scope.

The body of a blocks template: the block tree plus the page settings wrapped around it. An html template has none of this and carries html instead.

It REPLACES wholesale. A PATCH that sends document sends the whole document, so a call that rebuilds body and omits fonts drops the fonts.

GET/templates/{id}/versions/{version}

Retrieve one version

Разрешенияtemplates:readЧитает

One frozen revision with its body: document for the blocks engine, html for the html engine, plus the subject, slots and props that were declared at the time.

This is what the version LIST leaves out, and it is the only way to see what an old version holds without changing anything. Restoring used to be the only route to that, and a restore moves the head, so reading version 3 cost you your draft. It does not any more.

Use it to diff a regression against the revision that worked, to copy a block out of an older design, or to archive what a campaign actually said. POST /templates/{id}/versions/{version}/restore is still the call that brings it back.

DELETE/templates/{id}/versions/{version}

Delete one version

Разрешенияtemplates:writeУдаляет

Removes one revision and leaves the template alone. It is for tidying a long version list, not for changing what sends.

Three versions are refused, each as a 422 rather than a quiet success: the LIVE one, because sends resolve it; the HEAD, because that is the draft being edited, and restoring an older version first is how you move off it; and the only version a template has, because a template with no versions could not be read, so delete the template instead.

Mail already sent is untouched, since a send stores what it rendered. A send that pins a deleted version starts failing with template_version_not_found, and the number is never reused.

POST/templates/{id}/versions/{version}/restore

Restore an older version

Разрешенияtemplates:writeИзменяет данные

Copies an older version's subject, body, slots and props forward into the head, which is how a design you regret is undone. Nothing is rolled back in place: the old version stays in the list and the restored copy becomes the current draft.

A published head mints version N+1; a draft head is overwritten, so restoring twice does not pile up versions. It does not publish, so live sends do not move until you do, and the restore is itself reversible until then.

Restoring the head is a 422 rather than a no-op, because it would silently do nothing. expectedVersion guards against a concurrent editor exactly as it does on a PATCH.

POST/templates/{id}/preview

Render without sending

Разрешенияtemplates:readЧитает

The endpoint to point CI at. It resolves a version, substitutes the values and hands back exactly what a send would put in the message, so a template change is caught by a test rather than by a customer.

Lenient where a send is strict: a missing required prop comes back in warnings rather than refusing, because a template being previewed is usually a template being written. A send gets no such leniency. version may name a DRAFT here, which is the other thing a send cannot do.

Always application/json, never text/html. The HTML is a string field. A raw document would be JSON.parsed by every SDK transport and resolve to nothing at all.

GET/templates/{id}/analytics

How a template has performed

Разрешенияtemplates:readЧитает

The report the console shows on a template: how much it sent, how much of that was tracked, how much was opened and clicked, and the same figures by day, by source and by version.

Rates are computed over what was TRACKED rather than over everything sent, because a message sent with tracking off can never report an open and counting it would quietly lower every rate. Both denominators are in the response so nothing has to be taken on trust.

lifetime ignores the window: every live send ever, the test-key sends counted separately, and the first and last time it sent. A template that has never sent answers with zeroes rather than a 404; the 404 is for a template that does not exist.

POST/templates/{id}/send

Send with a template

Разрешенияtemplates:writeemails:sendОтправляет почту
Учитывает Idempotency-Key

Resolves the published version (or the one version pins), substitutes props and slots, and sends. subject overrides the version's own for this message only.

Props are validated STRICTLY, which is the opposite of the preview: an unknown key is refused rather than ignored, and a declared required key that is missing is refused rather than rendered as a blank. Mail cannot be recalled, and a hole where the order number should be is not something a recipient can report back to you.

Also requires emails:send, and neither scope is redundant: reaching a stored body is templates:write, mail leaving the workspace is emails:send. A key that may send its own bodies still cannot send somebody else's template.

POST /emails takes a template field that does the same thing, for a caller already composing a message.

List template images

cursorstring

The previous page's nextCursor, passed back as it came. It is opaque: it holds where the last row sat in this list's order, so a row deleted or edited between pages never breaks the walk, and the next page starts at the first row that sorts after it. A value this list did not hand out is a 400 invalid_cursor.

Design a template from a brief

Разрешенияtemplates:writeИзменяет данные

A designer builds a new block template from a written brief, the way the assistant in the app does, and saves it as a draft unless publish is true. starter builds on a starter design, and imageFileIds names up to ten uploaded or received images to place in it. It spends one AI action and can take up to a minute.

One web font the template loads. A mail client that blocks the download falls back to fallbackFontFamily, so name a real stack there rather than a second web font.

What renders when the web font does not, for example Georgia, serif. Required: a font with no fallback is a message that renders in whatever the client picked.

Where the file lives. Leave it out for a font already installed on the reader's machine, such as Georgia or Arial, which costs no download and is the safer choice in mail.

The url the named family is served from, exactly as GET /templates/fonts reports it. Any other url is a 422: a font file is fetched by the reader when the mail is opened, so an arbitrary host would be told who opened what and when, whatever the workspace has tracking set to.

Byte for byte what a send with these values would put in the message.

A letter followed by letters, digits or underscores. This is what {{key}} in the subject or the body refers to, and what a send names in props or slots.

kindstring

How a supplied value is escaped when it lands in the body. text becomes a React child, so React escapes it; url and image are parsed and scheme-checked before they reach an href or a src. The kind is declared rather than sniffed from the value, because a string that happens to start with https: is not evidence that the author meant it to be followed.

A required prop missing at send is a 422 and no mail leaves. That refusal is the most valuable rule in the feature: the alternative is a message going out with a blank where the order number should be, which nothing reports, nobody notices, and no one can recall.

documentobject

The body of a blocks template: the block tree plus the page settings wrapped around it. An html template has none of this and carries html instead.

It REPLACES wholesale. A PATCH that sends document sends the whole document, so a call that rebuilds body and omits fonts drops the fonts. Read the head with GET /templates/{id} (or an older revision with GET /templates/{id}/versions/{version}), change what you mean to change, and post the result back.

Page style for the whole message, as a CSS property bag in camelCase or kebab-case, for example { "backgroundColor": "#f5f5f5" }. Only the properties mail clients honour are accepted, and a rejected one is a 422 naming itself and listing what is allowed.

slotsTemplateSlot[]

The same list as the top-level slots on a create or a PATCH. Sending both is allowed and the top-level one wins.

propsTemplateProp[]

The same list as the top-level props, with the same precedence.

The trimmed form has no id on it either, so /emails/{id}/tracking rather than /tracking/{id} is the way back to the rest of it.

objectstring

Present when the report is the whole response body. Absent under an email's tracking field, which is part of that email rather than a resource in its own right.

Одно из"tracking"
idstring

The tracking record, tmsg_ + 24 hex. Not the message id and not the send id.

sendIdstring

The msg_ this went out as, when the send service handled it. Null for mail the mailbox agent sent on its own behalf, which is most composer, MCP and assistant traffic. Those messages do get a send record, but nothing links this tracking row to it. Tracking covers the mailbox rather than only the traffic that came through this API.

RFC 5322 Message-ID. Not a correlation key. The header is rewritten on the way out. Correlate on id.

opensboolean

What was APPLIED to this message, resolved when it was sent from the setting of the address it was sent from (its own, else its domain catch-all's, else off, while a broadcast copy is on unless the broadcast or its address turned it off) and any per-send override, not what is switched on now. Turning tracking on today does not make yesterday's mail start reporting, and a report that implied otherwise would read as "nobody opened it".

clicksboolean

As opens, for link rewriting. The two are independent switches.

openedboolean
clickedboolean
attributableboolean

Whether every reading on this message can be pinned to a named recipient. False as soon as an unattributed copy has activity of its own, which is what happens whenever one body went to the whole list rather than a separate one per person. This is the flag that decides whether "Bob has not opened it" is a sentence a client is entitled to write, or whether all it may say is that somebody did. recipients carries the same fact one row at a time, and one row at a time is where it gets missed.

openCountinteger

Opens that looked like a person, with repeat fetches within thirty seconds collapsed. A preview pane redrawing is not a second reading. Through Gmail this is a floor and not a total: its proxy fetches the image once and caches it, so later readings never reach us.

clickCountinteger

Counted clicks. Stronger evidence than an open, and worth weighting as such: images are blocked far more often than links go unfollowed, so a message with clicks and no opens was certainly read.

openCountRawinteger

Every open hit, the automated ones included. openCountRaw - openCount is everything that was filtered out: Apple Mail Privacy Protection and corporate link scanners, which fetch on delivery whether or not a person ever looks, and alongside them the repeat fetches collapsed by the thirty-second window. Both are recorded and neither is counted, because discarding them outright would leave a gap in the log that nothing could explain. Do not read the difference as a machine count on its own. A message reopened twice in a minute lands in it too.

clickCountRawinteger

As openCountRaw, for clicks.

recipientsobject[]

One entry per tracked copy, which is not always one entry per person. Absent only from the trimmed form on a GET /emails row; every /tracking response carries it, list included.

emailstring

Null where the bytes could not be varied per person: an encrypted message, one too large to rebuild for each recipient, or a fallback carrier that takes the whole recipient list in a single call. The reading is real; which of the recipients did it is not knowable, and the only honest rendering is "someone on this message", never a name chosen out of the list.

attributedboolean

False on exactly the rows described above. Branch on this rather than on email being a string, and show nothing where it is false: attributing an unattributed open to a named recipient invents evidence about a specific person.

linksobject[]

The rewritten links, in the order they appeared in the message. Only links in the new part of the body are here: the quoted history under a reply belongs to whoever wrote it, and routing their URLs through our redirector would both rewrite their message and record the recipient "clicking" something we did not put there. Repeated destinations share one entry, because a campaign page linked from a header image, a button and a footer is one question asked three times. Absent only from the trimmed form on a GET /emails row.

idstring
urlstring

Where it actually goes: the original href.

labelstring

The text the link read as in the message, where it had any. A bare URL rarely tells the sender which of five links somebody followed.
