Confirm an authorization

Confirms the current confirmable `nextAction`. Upon confirmation, Collate may proceed from the exact authorization version captured by the request. Call this endpoint to resolve the current confirmable `nextAction`. The server derives the action from the authorization state and the `If-Match` version; clients do not echo an action ID. Confirming `continue_authorization` lets Collate continue discovery, filling, validation, or submission preparation from the current snapshot. The authorization transitions to `processing`. Confirming `approve_submission` accepts the current `submission.reviewSnapshot.id` and lets Collate cross the final payer-submission boundary. Final approval is irreversible. If the snapshot no longer covers the current authorization, the request is rejected with `409 review_stale`. Do not call this endpoint to resolve `resolve_requirements`. Resolve that action by patching answers or attaching files. See [Authorization lifecycle](/lifecycle) for the full transition model. ## Returns Returns the accepted authorization. The response does not wait for portal work, payer receipt, or a payer decision.
