Identical to the documented `PUT` on the same path — Rails routes both verbs to the same action, so use whichever your client prefers. `custom_attributes` is **merged**, not replaced: keys you send are added or overwritten and keys you leave out stay. Use the destroy-custom-attributes endpoint to remove one. ## OpenAPI ````yaml /api-reference/openapi.json patch /api/v1/accounts/{account_id}/contacts/{id} openapi: 3.0.4 info: title: Tied API description: >- The Tied REST API.
