Update Board

Workspace API key (e.g. formo_xxx). Create one in the Formo dashboard under Team Settings > API.

Optional unique value (e.g. a UUID v4) that lets you safely retry POST/PUT/PATCH/DELETE requests. The first request runs normally; subsequent requests with the same key replay the stored response (status + body) for 24 hours, so retries can never double-create or double-charge. Two concurrent requests with the same key return 409 IDEMPOTENCY_IN_PROGRESS. Generate a fresh key per logical operation.
