GEThttps://forumulate.com/api/public/orgs/{orgId}/spaces/{spaceId}/forum/categories/overview

The forum's categories page as a reader sees it: each visible category with its newest topic (latest, or ?latest=N of them in latestTopics), topics per week, and — for a signed-in reader — unread and new counts. restricted marks a category an anonymous reader may not enter, so the reader can draw a lock.

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:

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.

Schema
errorobjectrequired
Show child parameters
codestringrequired
Stable, machine-readable error code, e.g. rbac.forbidden.
messagestringrequired
Human-readable explanation.
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.
conflictobject
On a 409 from a content entry field write (PATCH …/entries/{entryId}/fields) whose If-Match was stale.
Show child parameters
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.
404 No such thing — one of the ids in the path does not resolve, or resolves to something this caller may not see (*.not_found).
