Record one immutable human Decision against an exact proposal action.

POST /api/v1/interactions/{interactionId}/decisions

Requires exact revisionId, actionId, proposal fingerprint, current strong If-Match, and Idempotency-Key. The first valid result is immutable; replay never retargets a later revision. A Decision is intent, not Fulfillment or execution evidence.

Access

Use a credential with the authentication scheme documented in the API contract.

Provider access, workspace membership, and agent grants are enforced separately. A token does not expand access to a repository or resource. Set up developer access.

Recover from errors

Use the returned status and error body. Correct invalid fields before retrying; reconnect or narrow the target for authentication and permission errors. For conditional writes, reload the latest version before preparing a new request. Respect rate-limit headers and retry only when the operation’s idempotency contract permits it.
