API

API authentication and keys

Send your key as Authorization: Bearer op_live_... or in X-Api-Key. A key is bound to one workspace and to the member who made it, with scope read or write. It acts with that member's role and stops working if they leave. A read key cannot change anything.

Updated 2026-10-26

What a key can do

  • Scope read: GET routes only.
  • Scope write: every route the member's role allows.
  • A contributor's key saves posts into review even when the request asks to publish.
  • Approving needs a role that approves and the approval switch only the workspace owner sets.

Every route in the API reference lists the role action and the key scope it needs. Keys are shown once when made; store them like a password.
