# engagements.recordExecution

Administrator explicitly records that the reviewed engagement terms match the linked completed signing envelope. Requires no unresolved terms, the fresh reviewedTermsHash from engagements.get and expectedEnvelopeRevision. This is evidence recording, never signing or accepting a contract. Only do this when the person explicitly confirms the match. It freezes this version; future changes need engagements.revise. Does not infer any payment.

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | string (ID) | Yes | The record's ID. |
| `expectedRevision` | integer | Yes | The record's current revision, from the last time you read it. If someone changed the record since, the request is refused with a conflict so you can reload and check before trying again. 1 to 9007199254740991. |
| `idempotencyKey` | string | Yes | Any unique text you generate once per intended change, so a retried request only happens once. Send it as the Idempotency-Key header instead if you prefer; if you send both they must match. 8–200 characters. |
| `expectedEnvelopeRevision` | integer | Yes | The related record's current revision, from the last time you read it. 1 to 9007199254740991. |
| `reviewedTermsHash` | string | Yes | SHA-256 hash as 64 lowercase hex characters. |
