# signing.envelopes.keep

Keep an envelope that is waiting on suggested changes as it is: every suggested change is declined with the reply (and optional replies per change), signing resumes where it was, and each person who suggested changes gets the reply with a fresh link.

## 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. |
| `requestIds` | array of strings (ID) | Yes | A list of record IDs. 1–20 items. |
| `reply` | string | Yes | 3–2000 characters. |
| `replies` | map |  |  |
| `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. |
