}Update theme settings
Shallow-merges theme over the project’s own theme settings. Send only the top-level keys you want to change; theme must contain at least one key.
Nested objects are replaced wholesale. Fetch the current settings first when you need to preserve sibling values inside a nested object.
- Writes the project’s own config only; a parent project’s theme is never changed through a child project.
updatedKeyslists the top-level keys whose stored value actually changed. It is empty for a no-op patch, in which case no cache invalidation happens.- When values change, a theme version snapshot (restorable from Studio) is attempted before the write. Snapshots are deduplicated and best-effort, so do not assume every update has one.
- After a change, caches are invalidated like a Studio save so the edit goes live through api.weaverse.io. Propagation time is not guaranteed; read the settings again to verify.
- Clients or proxies that strip
PATCHbodies may sendPOSTto the same URL.
Concurrency: pass the revision from your GET as expectedRevision. If the settings changed since, the request returns 409 STALE_PROJECT and writes nothing; re-read and reapply. Delegated (MCP OAuth) tokens must send it (428 PRECONDITION_REQUIRED otherwise); it is optional for API keys.

}Authorizations
Bearer token: a shop API key (WEAVERSE_API_KEY), a scoped API key or a delegated MCP OAuth token; translation-unit routes also accept a project-bound translation agent token. Each operation lists the scope it requires; the scope table is in the API description.
Path Parameters
Body
Top-level theme settings keys to merge. Must be a non-empty object.
Optimistic-concurrency token: the revision value from the GET read this patch was based on (null when GET returned null for a project whose revision was never set; compared null-safely). Required for delegated (MCP OAuth) tokens — omitted → 428 PRECONDITION_REQUIRED; optional for API keys. When the settings changed since (e.g. a concurrent studio save), the request is rejected with 409 STALE_PROJECT before anything is written. Re-read and reapply instead of retrying the same patch.
Response
Merge result with the full stored theme
