Response Errors ​

  • 400 invalid update payload (CUSTOM_FIELDS_*, POST_TYPE_LOCKED, …)
  • 401 missing session
  • 403 not owner/admin or APPROVAL_REQUIRED on publish
  • 404 post not found

Notes ​

  • Use this for content edits and metadata changes.
  • Keep slug and visibility in sync with the publishing flow.
  • CPT: custom_fields are updatable; changing post_type returns POST_TYPE_LOCKED.
  • Type behaviors may still apply on publish (approval, scheduling, password visibility).
