# documents.history.restore

Restore a saved version of an agreement template as a new change (id from documents.history.list and an idempotencyKey): its text, name, letterhead, footer, logo and signers go back, checked and audited like any edit. Earlier versions stay in the history.

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `documentType` | "agreement_template" | Yes |  |
| `documentId` | string (ID) | Yes | The ID of the related record. |
| `id` | string (ID) | Yes | The record's ID. |
| `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. |
