# signing.envelopes.revise

Answer the changes signers suggested to an envelope that is waiting on them by sending a revised version: decisions has, for each open request id, a decision per suggested change (accepted, rejected, or noted for a comment), optionally with the wording the sender accepts instead (text) and a reply. Accepted changes go into the agreement's text, a new envelope is prepared and sent to every signer again, and the old one is cancelled as replaced; signatures on it stay in its record. Optional reply to all signers and a new deadline (expiresAt). Requires at least one accepted change.

## 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. at most 9007199254740991; greater than 0. |
| `decisions` | map | Yes |  |
| `reply` | string |  | at most 2000 characters. |
| `expiresAt` | string (date-time) |  | When this stops working, as an ISO 8601 date and time. |
| `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. |
