POSThttps://forumulate.com/api/orgs/{orgId}/theme-library

Save as theme: keeps what a space or site wears now as a reusable library entry, without the logo or any script, ready to apply elsewhere, download, or submit to the marketplace.

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
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.

201 Created. This 201 is a RESULT, not a create: no addressable resource was made, so there is no data mirror and nothing to GET back. An acknowledgement, a computed answer, a tally or a one-time credential — read the keys this response documents.

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.

403 Authenticated, and not allowed — always rbac.forbidden, whether what is missing is the capability, the token scope, or a resource the token is pinned away from. The message names the capability and, for a scope refusal, the scopes that would grant it. A refusal because of the PLAN is a 402 with quota.exceeded, not this.
