PUThttps://forumulate.com/api/orgs/{orgId}/spaces/{spaceId}/blog/tags/{slug}/page

Composes a tag’s landing page from blocks, the same document a front page takes. Every feed of this blog on it shows the tag’s posts unless it names tags of its own.

Requires token scope: write (the coarse method gate) for Atlas key (ak_), Personal Access Token (cft_) or OAuth (cfo_) auth — in addition to any catalog scope (GET /pats/scopes) the route’s capability needs. Session/cookie auth is governed by RBAC capabilities instead.

Parameters

orgIdstringpathrequired

spaceIdstringpathrequired

slugstringpathrequired

forumulate-versionstringheader

API version negotiation. Send forumulate-version: 2026-12-01 on every request from a new integration; it is optional only so that integrations written before versioning keep working. Each version includes everything before it:

Idempotency-Keystringheader

Makes this write safe to retry. Optional — send any unique string (a UUID is ideal) and the first request runs while its response is remembered under that key for 24 hours; an identical retry replays that same status and body instead of acting twice, so a timeout or a 5xx from the edge can be retried without creating a second row. A retry sent while the first request is still in flight is refused with 409. The key is scoped to the method and path, so the same key on a different endpoint is a different request. Error responses of 5xx are never cached — those retries re-run. A key is bound to the BODY it was first used with: reusing it with a different body is a 409 idempotency.key_reused, not a replay, because replaying would tell you a write landed that never ran. Generate one key per request, never per process or per session.

customCssstring

CSS for THIS piece only, after the space theme so it wins. Sanitised and scoped to the reader exactly like the space customCss (@import dropped, no way out of the <style>).

themeobject

A partial theme for this piece — colours, palettes, fonts, typography, colorScheme, components, contentWidth, layout, motion, and (on a blog post) post — layered over the space’s (which is over the site’s). On a post, release, event or legal document PATCH it MERGES key by key like the space theme’s PATCH, and null clears at any depth ({"paletteDark": null}); a page’s metadata replaces it whole. Unknown keys are refused by name. null clears all of it.

summary (thumbnail) or summary_large_image (the default).

jsonLdstring

Structured data for this piece, as JSON (object or array of objects). Replaces the automatic markup on this piece (Article/BlogPosting, Event, DiscussionForumPosting/QAPage, the roadmap item’s Article). null restores the automatic one.

warningsstring[]

Values we ACCEPTED and then rewrote, one sentence each — a slugified tag, a normalised colour, a clamped range, a slug that was taken. Absent when nothing was rewritten, never []. The same sentences are on the X-Field-Warnings response header. If this is present, something you sent is not what is stored; read the resource back rather than assuming your own value.

400 The request could not be understood — a malformed header, path or query value (request.malformed). A value that was understood but is not acceptable is a 422 validation.failed.

detailsobject

Field-level validation problems, keyed by field path (422 only).

docsstring

Where the vocabulary or format this error is about is published — an absolute URL, or an API route such as GET /space-types/{type}/presets. Present on errors over a controlled list, so the answer to "what am I allowed to send?" is in the error itself.

reasonstring

Why a credential was refused, as one stable word, where one status has several causes — e.g. an external_jwt redeem answers iat_too_old, iat_in_future, bad_signature, bad_issuer, bad_audience, expired and more. Branch on this, not on message.

slugsstring[]

The exact slugs that collided, on a slug-conflict 409 — space.slug_taken, page.slug_taken, collection.slug_taken, site.slug_taken or badge.slug_taken.

etagstringrequired

The entry's current fields etag.

opsarrayrequired

The field operations since your If-Match that touch a path your own operations touch. Empty: none did — retry the batch unchanged under etag. null: the history no longer reaches your tag — re-read the entry first.

requestIdstring

The id of this request — the same value as the x-request-id and x-forumulate-request-id response headers. Quote it in a bug report: it is the only thing that finds your exact request in our logs. It is in the body because that is the part that survives — an SDK that throws the parsed body, a serverless log that keeps the body and drops the headers, a ticket with the JSON pasted in.

401 No credential, or one that is expired or revoked (auth.required). Send a Bearer token or the session cookie.
