Templates.ListAsync
List templates, most recently updated first
Task<Page> ListAsync( string? status = null, string? search = null, string? sort = null, int? limit = null, string? cursor = null, string? apiKey = null, CancellationToken cancellationToken = default)Returns one page of the workspace's templates, ordered by updatedAt descending. Each row carries the published version's subject, engine, slots and props, so you can see what a send needs without fetching every template. A template with nothing published omits those four fields and reports publishedVersion as null.
Paging is keyset on updatedAt, and the cursor is opaque: it holds the sort and where the last template on the page sat in it, so a template deleted while you page never breaks the walk. Editing a template moves it to the front, so a template changed while you page can show up twice. Pass nextCursor back as cursor: while hasMore is true, or let ListAllAsync or IterateAsync walk the pages for you.
status: narrows to one template status. draft is the status of a template created without publish and never published or activated since. It does not mean "has unpublished edits": check latestVersion against publishedVersion for that.
المعلمات
statusstring?Restricts the page to
draft,activeorarchivedtemplates. Omit it for all of them.searchstring?Matches the name, the slug, the description, the published version's subject and the id, each word loosely, with close spellings when nothing matches exactly, as a substring.
%and_are taken literally.sortstring?The order:
updated-newest(the default),updated-oldest,created-newest,created-oldest,nameorname-reversed. The cursor follows whichever you asked for.limitint?Rows per page, a whole number from 1 to 100. The server defaults to 25.
cursorstring?The
nextCursorfrom the previous page. Never build one yourself.apiKeystring?Overrides the client API key for this call only.
cancellationTokenCancellationTokenCancels the request.
يُرجع
A Page with items, hasMore and nextCursor. Each template has id, name, slug, description, status, publishedVersion, latestVersion, createdAt and updatedAt, plus subject, engine, slots and props when a version is published.
مثال
var page = await client.Templates.ListAsync(status: "active", limit: 50); foreach (var template in page){ Console.WriteLine($"{template["slug"]} published v{template["publishedVersion"]?.ToString() ?? "-"}, latest v{template["latestVersion"]}");} if (page.HasMore){ var next = await client.Templates.ListAsync(status: "active", limit: 50, cursor: page.NextCursor); Console.WriteLine($"The next page starts with {next.Items[0]?["slug"]?.ToString() ?? "nothing"}");}ملاحظات
A cursor is only valid under the sort it was handed out with. Keep
sortandsearchthe same while you page, whichListAllAsyncandIterateAsyncdo for you.A cursor this list did not hand out, or one handed out under another
sort, is a 400invalid_cursor, not an empty page. Start again without a cursor.publishedVersionlower thanlatestVersionmeans the body was edited after the last publish, and live sends still use the published version.publishedVersionis null for a template that has never been published, here and onGetAsync,CreateAsyncandUpdateAsyncalike.

Templates.ListAllAsync
Collect every template into one object
Task<IReadOnlyList<JsonObject>> ListAllAsync( string? status = null, string? search = null, string? sort = null, int? limit = null, string? cursor = null, string? apiKey = null, CancellationToken cancellationToken = default)Walks every page of the template list and returns all of them in a single object, most recently updated first. It follows nextCursor until hasMore is false, so the number of requests is the template count divided by the page size.
A workspace holds at most 200 templates, so passing limit: 100 normally finishes in two requests. status: collects only one status. Paging is keyset on updatedAt, so a template edited by someone else during the walk can appear twice: de-duplicate on id if other writers are active.

يُرجع
A list of JsonObject items holding every matching template, each with id, slug, status, publishedVersion and latestVersion, plus the published subject, engine, slots and props where one exists.
مثال
var templates = await client.Templates.ListAllAsync(limit: 100); Console.WriteLine(templates.Count);ملاحظات
Each page is a separate request. If one fails the call throws and the pages already fetched are discarded.
Archived templates count towards the 200 limit, and only
DeleteAsyncfrees a place.Use
IterateAsyncwhen you only need the first match, since it stops fetching once you break.

Templates.IterateAsync
Stream templates one at a time
IAsyncEnumerable<JsonObject> IterateAsync( string? status = null, string? search = null, string? sort = null, int? limit = null, string? cursor = null, string? apiKey = null, CancellationToken cancellationToken = default)Returns an IAsyncEnumerable<JsonObject> that yields templates individually and requests the next page only after the current one is drained. Nothing is fetched until you start consuming it, and breaking out of the loop stops further requests, so this is the cheapest way to find one template by a property the API cannot filter on.
The walk follows nextCursor and ends when hasMore is false, when a page carries no nextCursor, or when the server repeats a cursor. Order is most recently updated first, so a template edited while you iterate can be yielded twice. Collect ids during the loop and act on them afterwards if you are also writing.

Templates.GetAsync
Read a template with its head version in full
Task<JsonObject> GetAsync( string idOrSlug, string? apiKey = null, CancellationToken cancellationToken = default)Fetches one template by tpl_ id or by slug. Every templates method accepts either, and the two cannot collide because ids carry the tpl_ prefix while a slug has no underscores. Pin the slug in code: it is derived once at creation and never changes when the template is renamed.
latest is the head version, meaning the current draft, or the published version when nothing has been edited since. This is the only read that returns the body: document for the blocks engine, and html for the html engine exactly as submitted, before sanitising. The top level subject, engine, slots and props describe the published version, which is what a send uses, so they differ from latest while somebody has unpublished edits.
When nothing has been published yet, publishedVersion is null and the top level subject, engine, slots and props are absent. Read the draft from latest instead. Use ListAsync or ListVersionsAsync to find out whether a template can actually be sent.

Templates.CreateAsync
Create a template and its first version
Task<JsonObject> CreateAsync( IReadOnlyDictionary<string, object?> body, string? apiKey = null, CancellationToken cancellationToken = default)Creates the template together with version 1. Without ["publish"] = true that version is a draft, and a draft cannot be sent: SendAsync answers 422 template_not_published until somebody calls publish. With ["publish"] = true the body is compiled straight away and the template starts active, so a body that fails to render is refused here instead of later.
The engine follows what you send. Posting html selects the html engine, anything else is blocks. A blocks template stores a document whose body is a tree of @react-email/components nodes (Section, Row, Column, Container, Text, Heading, Button, Link, Img, Hr, Markdown, CodeBlock and CodeInline), validated on the way in with a ceiling of 500 nodes nested 8 deep. An html template stores markup you rendered yourself, for example with @react-email/render in your own build, and it is sanitised when the version is compiled.
A placeholder is a key between double braces, and it is filled from declared slots and props. A slot has a default and belongs to whoever edits the template. A prop is supplied by the sender and can be required. Keys start with a letter and continue with letters, digits or underscores, and one key cannot be both. In a blocks template an undeclared placeholder is a 422 invalid_template naming its path. In html markup, any placeholder used inside an attribute such as href or src must be declared with kind url or image, or compiling fails.

Templates.UpdateAsync
Edit template metadata or its draft body
Task<JsonObject> UpdateAsync( string idOrSlug, IReadOnlyDictionary<string, object?> patch, string? apiKey = null, CancellationToken cancellationToken = default)Changes a template in place. name, description and status are metadata and never create a version. Sending any of subject, document, html, slots, props or engine is a body edit: if the head version is still a draft it is overwritten, and if the head is published a new draft numbered one higher is minted. Body fields you leave out keep the head's values, so a patch carrying only subject keeps the existing document and declarations, while slots or props replace the whole list.
Nothing here changes what a live send returns. Sends keep using the published version until you call PublishAsync, which is what makes it safe to edit a template in production. The response's latest is the version this call wrote into.
Pass expectedVersion with the latestVersion you read before editing. If another writer has moved the head since, the call fails with 409 version_conflict instead of overwriting their change. Without it the last write wins. Setting ["status"] = "archived" is the reversible alternative to delete: an archived template refuses to send with 422 template_archived until its status is active again.

Templates.DuplicateAsync
Copy a template into a new one
Task<JsonObject> DuplicateAsync( string idOrSlug, IReadOnlyDictionary<string, object?>? body = null, string? apiKey = null, CancellationToken cancellationToken = default)Creates a new template from the HEAD version of an existing one: the same subject, body, slots and props, and the source's description. The copy starts at version 1 as a DRAFT, whatever the source had published, so a copy is never sendable by accident. Publish it when you mean to.
The copy is a separate template with its own id and slug. Nothing links it back to the source, so editing either one afterwards leaves the other alone. This is 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 because a name is unique per workspace the server appends a number until one is free, up to twenty attempts. Sending a name that is already taken behaves the same way, so a script that copies nightly keeps working.

A JsonObject for the NEW template, with latest set to its version 1 draft, including the copied document or html. The server answers 201.

The copy takes the source's HEAD, which is the unpublished draft when there is one. Duplicate after publishing if you want the live body.
Not retried by the SDK. Calling it twice makes two copies, each with its own numbered name.
A workspace at its 200 template limit is a 422
workspace_limit_reached, and nothing is copied.Every name from the base to the base plus 20 being taken is a 409
template_name_taken.

Templates.ReplaceContentAsync
Swap a template's design for a starter or another template's
Task<JsonObject> ReplaceContentAsync( string idOrSlug, IReadOnlyDictionary<string, object?> body, string? apiKey = null, CancellationToken cancellationToken = default)Replaces the whole body of a template with a starter design or with another template's body, keeping the template's own identity: its id, slug, name, description and status do not move, and neither does what a live send returns.
The write lands exactly where an UpdateAsync to the body lands. A draft head is overwritten in place; a published head mints version N+1 as a draft. Sends keep resolving the published version until you publish, so this is safe to call on a template that is sending.
Name exactly one source. starter takes a slug from ListStartersAsync; fromTemplateId takes another template in the same workspace, whose published version is copied when it has one and whose draft is copied otherwise. Sending both, neither, or the target itself is a 422. A source in another workspace is a 404, like everything else here.
This discards the body it replaces. A version that was published is still in the version list and can be restored, but an unpublished draft body is gone.

The new body brings the source's slots and props with it, replacing the target's declarations entirely. A send that passed the old props may start failing with
unknown_template_prop, so read the response before publishing.A template cannot replace its own design: that is a 422
invalid_templateonfromTemplateId.Not retried by the SDK. With
expectedVersionset, a repeat after a lost response is a 409 if the first attempt landed.

Templates.DeleteAsync
Delete a template and every version
Task<JsonObject> DeleteAsync( string idOrSlug, string? apiKey = null, CancellationToken cancellationToken = default)Permanently removes the template and all of its versions. There is no undo. Mail already accepted is unaffected, because each send stores the body it rendered, but any integration still sending against this id or slug starts receiving 404s.
If you might need the template again, archive it with UpdateAsync(idOrSlug, new Body { ["status"] = "archived" }) instead. The response is a tombstone rather than an empty body, so a log line can record exactly what was removed.

Deleting frees both the name and the slug. A template created later with the same slug gets a new
tpl_id.Archived templates still count towards the 200 template limit, so deleting is the only way to make room.

Templates.ListVersionsAsync
List one page of a template's versions, newest first
Task<Page> ListVersionsAsync( string idOrSlug, int? limit = null, string? cursor = null, string? apiKey = null, CancellationToken cancellationToken = default)Returns one page of a template's versions, newest first. Every publish adds a version, so a template edited for a long time holds many: follow nextCursor while hasMore is true to reach version 1, or let ListAllVersionsAsync and IterateVersionsAsync do that walk. At most one version is a draft and it is always the highest number. Every version below it has been published, and the highest published version is the one unpinned sends use.
Bodies are left out, so document and html are absent on every row. What each version declares (subject, slots and props) is present, which makes this the call for checking what pinning a version on SendAsync would commit you to.
Pages are keyset on the version number, so a version deleted while you walk never breaks the walk: the next page starts at the first version below the cursor.

This is what ListVersionsAsync leaves out. It is the only way to read an old version without changing anything: RestoreVersionAsync also shows you the body, but it moves the head to get there, so reading version 3 used to cost you your draft.

Task<JsonObject> PublishAsync( string idOrSlug, int? expectedVersion = null, string? apiKey = null, CancellationToken cancellationToken = default)Freezes the head version and makes it the one unpinned sends use. Compiling happens here: a blocks tree is rendered through react-email and html markup is sanitised, so a body that does not render fails with 422 invalid_template for the person publishing rather than for a recipient. Nothing is published when that happens.
The call is idempotent. If the head is already the published version it comes back unchanged, so a deploy script can publish on every run. Publishing also sets the template's status to active, which reactivates an archived template.
Only the head can be published, and there is no call to republish an older version. To keep production on an earlier version while a new one is prepared, pin that version on SendAsync. The response is the published version with the updated parent attached as template.

A JsonObject for the head version with state set to published and publishedAt set, without document or html, plus template, an object for the parent template showing the new publishedVersion and status.

var published = await client.Templates.PublishAsync("order-shipped"); Console.WriteLine($"v{published["version"]} published at {published["publishedAt"]}");Console.WriteLine($"Live version {published["template"]?["publishedVersion"]}, {published["template"]?["status"]}");ملاحظات
The SDK retries this call on network errors and retryable statuses, which is safe because publishing twice lands in the same place.
The server answers 201 even when nothing changed.
Sends that pin an earlier
versionare unaffected. Only unpinned sends move to the new version.An
htmlplaceholder used inside an attribute with kindtextfails here withparamset toprops.<key>.

Templates.RestoreVersionAsync
Bring an older version's body back as the draft
Task<JsonObject> RestoreVersionAsync( string idOrSlug, int version, IReadOnlyDictionary<string, object?>? body = null, string? apiKey = null, CancellationToken cancellationToken = default)Copies an older version's subject, body, slots and props forward into the head, which is how you undo a design you regret. Nothing is rolled back in place: the old version stays where it is in the list and the restored copy becomes the current draft.
Where it lands follows the usual rule. A published head mints version N+1 as a draft; a draft head is overwritten, so restoring twice does not pile up versions. Live sends do not move until you publish, so a restore is reversible until then: restore something else, or publish to commit.
Restoring the head itself is a 422, because there is nothing to bring back. An unknown version is a 404. expectedVersion makes the call safe against a concurrent editor, the same as on UpdateAsync.

It does not publish. Until you call
PublishAsync, sends keep resolving whatever was live before.The restored body brings the old version's slots and props with it, so a send passing newer props may start failing with
unknown_template_prop.Restoring the current head is a 422
invalid_template, not a no-op.Not retried by the SDK, because a repeat can mint a second version.

Templates.DeleteVersionAsync
Delete one version of a template
Task<JsonObject> DeleteVersionAsync( string idOrSlug, int version, string? apiKey = null, CancellationToken cancellationToken = default)Removes a single revision and leaves the template itself alone. It is for tidying a long version list, not for changing what sends.
Three versions cannot be deleted, and each refusal is a 422 rather than a silent success: the LIVE version, because sends resolve it; the HEAD, because that is the one 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 at all, so delete the template instead.
Everything else is fair game. Mail already sent from a deleted version is untouched, since a send stores the body it rendered, but a send that pins a deleted version starts failing with template_version_not_found.

RestoreVersionAsyncwith an older version, which makes a new head, and the old head becomes deletable.Version numbers are never reused: deleting version 3 does not free the number.

Templates.ListStartersAsync
List the built-in starter designs
Task<IReadOnlyList<JsonObject>> ListStartersAsync( string? apiKey = null, CancellationToken cancellationToken = default)The starter designs the web editor offers, as a plain list. A starter is a ready-made block document with a subject and its declared slots and props, and it is the same catalogue the console shows, so an integration and a person building a template by hand start from the same place.
Bodies are left out here. slug is the handle to pass as starter to CreateAsync or ReplaceContentAsync, and GetStarterAsync returns one in full with its block tree and a rendered preview.
Starters are static: they are part of the product rather than workspace data, so this answer is the same for every key and changes only when a release adds one.

The preview is what the console shows in its starter picker, so a client can display the same thing without rendering anything itself. The document is there so you can seed a template from a starter and edit the tree before creating it, rather than creating from the starter and patching afterwards.

Templates.ListFontsAsync
List the web fonts a template can load
Task<IReadOnlyList<JsonObject>> ListFontsAsync( string? apiKey = null, CancellationToken cancellationToken = default)Every web font a template may load, as a plain list, in the order the web editor offers them. Each row names a family, the full CSS stack to write, the fallback a mail client shows when it cannot load the font, the weight range the file covers, and the url the file is served from.
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 font loaded from anywhere else would tell whoever runs that host when the message was read, whatever the workspace has open tracking set to. A template whose webFont.url is not the one listed here for its family is refused with 422 invalid_template.
Fonts are static: they are part of the product rather than workspace data, so this answer is the same for every key and changes only when a release adds one.

This is what the web editor calls while somebody types, and it is the call for checking a design in CI before it becomes a template.
Everything CreateAsync accepts as content is accepted here: document for the blocks engine, html for the html engine, plus subject, slots and props. values.props and values.slots fill the placeholders; anything left unfilled is rendered blank and reported in warnings, exactly as PreviewAsync does for a stored template.

Templates.PreviewAsync
Render a template without sending it
Task<JsonObject> PreviewAsync( string idOrSlug, IReadOnlyDictionary<string, object?>? body = null, string? apiKey = null, CancellationToken cancellationToken = default)Renders a version with the values you pass and returns the subject, HTML and plain text a send with the same values would produce. Nothing is sent or recorded. Point CI at it so a broken template is caught by a test rather than by a customer.
It renders the published version unless version names another one, and unlike SendAsync it can render a draft, which is compiled on the fly. A template with nothing published needs an explicit version, otherwise the call is a 422 template_not_published. Required props are relaxed here: a missing one renders its default or an empty string, and every placeholder that ends up blank is listed in warnings as unfilled_placeholder.
The other value checks still apply. A key the version does not declare is a 422 unknown_template_prop or unknown_template_slot, and a value that is not a string, number or boolean is a 422 invalid_template_prop. Values of kind url or image are parsed, and anything outside http, https, mailto, tel and cid renders as #.

Templates.GetAnalyticsAsync
How one template has performed
Task<JsonObject> GetAnalyticsAsync( string idOrSlug, int? days = null, int? minutes = null, string? grain = null, int? offsetMinutes = null, string? apiKey = null, CancellationToken cancellationToken = default)The engagement report the console shows on a template: how many messages it rendered in the window, how many of those were tracked, how many were opened and clicked, and the same numbers broken down by day, by source and by version.
Rates are computed against what was TRACKED, not against everything sent, because a message sent with tracking off can never report an open and counting it would quietly lower every rate. trackedForOpens and trackedForClicks are the denominators, and they are in the response so you can recompute anything yourself.
lifetime ignores the window: it is every live send this template has ever made, the test sends counted separately, and the first and last time it sent. recent previews the twelve newest sends in the window with their own open and click counts, which is the fastest way to see whether a template that was just published is behaving. It is a preview, not the list: ListSendsAsync returns every send in the window, a page at a time.

It is the list behind the numbers GetAnalyticsAsync reports, and the place to answer "did this person get it".
Paging here is by page number rather than by cursor, because the console shows a table with a total, and total is the count matching the filters rather than the size of the page. Pages are 25 rows by default and at most 100.
The filters narrow by window (days: or minutes:), by version:, by source:, and by engagement: opened:, clicked: and tracked: each take true or false. search: matches the subject and the recipient addresses. A row whose message carried no tracking reports matched as false and zero counts, which is not the same as nobody opening it.

Task<JsonObject> SendAsync( string idOrSlug, IReadOnlyDictionary<string, object?> body, string? idempotencyKey = null, string? apiKey = null, CancellationToken cancellationToken = default)Resolves the published version, or the one version pins, fills its placeholders from props and slots, and queues the message. Values are checked strictly here. An undeclared key is a 422 unknown_template_prop or unknown_template_slot, a missing required prop is a 422 missing_template_prop, and a value that is not a string, number or boolean is a 422 invalid_template_prop, each with param set to template.props.<key>. A template with nothing published, or a pinned version that is still a draft, is a 422 template_not_published. No mail leaves when any of these fail.
Pin version in production code. Without it every send resolves whatever is published at that moment, which changes the morning somebody publishes a rewrite. subject replaces the version's subject for this message only and is used exactly as written, with no placeholder filling. scheduledAt takes a DateTimeOffset (sent as an instant in UTC), an ISO 8601 instant or an ISO 8601 duration such as PT30M, up to 365 days out, and cannot be combined with a non zero cancellableForSeconds.
The SDK attaches an Idempotency-Key generated once per call and reuses it on that call's retries, so a retry replays the original message instead of sending a second one. Pass idempotencyKey: to deduplicate across processes and restarts, and derive it from what caused the send, never from a clock. A replay returns replayed set to true and the original message, while reusing a key with a different body is a 422 idempotency_key_reuse.

A JsonObject with id, url, size, width and height.
مثال
using OpenEmail.Constants; await using var photo = File.OpenRead("photo.jpg"); var image = await client.Templates.UploadImageAsync(photo); Console.WriteLine($"{image["url"]} {image["width"]}x{image["height"]}"); await using var logoFile = File.OpenRead("logo.png"); var logo = await client.Templates.UploadImageAsync(logoFile, contentType: TemplateImageTypes.Png); Console.WriteLine($"{logo["url"]}");ملاحظات
The SDK does not retry an upload, because a second one stores a second copy.
An image of another type, one over 5 MB, or one that cannot be read is refused with 422
invalid_image. A busy image service answers 503image_busyand a failed save 502image_not_stored.

Templates.DesignAsync
Design a new template from a brief
Task<JsonObject> DesignAsync( IReadOnlyDictionary<string, object?> body, string? apiKey = null, CancellationToken cancellationToken = default)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. It uses every block the editor has, with a palette, type and spacing, and the result opens in the visual editor fully editable.
Put everything the design must hold in brief: what it is for, the sections in order, the words, the colours and fonts, and which values change per recipient. starter builds on a starter design, and imageFileIds places up to ten uploaded or received images. It spends one AI action and can take up to a minute.
المعلمات
namestringمطلوبA short name for the template. When the name is taken, a free one is chosen and returned.
briefstringمطلوبEverything the design must hold and look like, up to 8,000 characters.
descriptionstringOne line about what it is for.
starterstringThe slug of a starter design to build on, from
ListStartersAsync.imageFileIdsIEnumerable<string>Up to ten file ids of images to place in the design.
publishboolPublish it at once so it can be sent. Defaults to false.
apiKeystring?Overrides the client's API key for this call only.

يُرجع
A JsonObject with the template, plus design, an object with the subject, the notes on what was adjusted and the imageProblems.
مثال
var template = await client.Templates.DesignAsync(new Body{ ["name"] = "Spring launch", ["brief"] = "A launch email for our spring collection: a hero image, three product cards and a button to the shop. Green and cream, friendly tone.",}); Console.WriteLine($"{template["id"]}: {template["design"]?["subject"]}");Console.WriteLine($"{string.Join(Environment.NewLine, template["design"]?["notes"]?.AsArray() ?? [])}");ملاحظات
The SDK does not retry it, because a second call designs and saves a second template.
A design that cannot be made valid is a 422
invalid_template, a server with no model a 409ai_not_configured, and a workspace out of AI actions a 429ai_quota_exceeded.An image id the key cannot reach is left out and named in the
imageProblemsofdesign.

Templates.RedesignAsync
Change a template’s design from instructions
Task<JsonObject> RedesignAsync( string idOrSlug, IReadOnlyDictionary<string, object?> body, string? apiKey = null, CancellationToken cancellationToken = default)A designer applies written instructions to a block template and leaves everything else alone: restyle it, change colours, fonts or spacing, rewrite or translate its copy, add, move or remove sections, swap an image. The change lands in the draft, so live sends keep the published version until you publish.
A raw HTML template cannot be redesigned and is refused with 422 invalid_template. It spends one AI action.

يُرجع
A JsonObject with the template, plus design, an object with changes (blocks edited, added and removed), draftVersion, the subject, notes and imageProblems.
مثال
var template = await client.Templates.RedesignAsync("spring-launch", new Body{ ["instructions"] = "Make the button orange and translate the copy into Spanish.",}); var changes = template["design"]?["changes"]; Console.WriteLine($"Draft v{template["design"]?["draftVersion"]}: {changes?["edited"]} edited, {changes?["added"]} added, {changes?["removed"]} removed");ملاحظات
The SDK does not retry it, because each call is a fresh design pass.
The same errors as
DesignAsync, plus 404 for a template that does not exist.
