`GET /api/v1/interactions/{interactionId}/messages/{messageId}/revisions`

Read retained reply history through a human browser session.

## Access

Use a credential with the authentication scheme documented in the API contract.

Provider access, workspace membership, and agent grants are enforced separately. A token does not expand access to a repository or resource. [Set up developer access](/docs/build/developer-access).

## Parameters

| Name | Location | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `interactionId` | path | string | Yes | Opaque Interaction id. |
| `messageId` | path | string | Yes |  |
| `cursor` | query | integer | No |  |

## Call the endpoint

Replace path placeholders and your credential. For body operations, create `request.json` using the required fields above; this command does not invent resource identifiers or consent.

```bash
curl --request GET \
  'https://commentary.dev/api/v1/interactions/<interactionId>/messages/<messageId>/revisions' \
  --header 'Authorization: Bearer <your-token>'
```

### Successful response fields

Value type: object.

## Recover from errors

Use the returned status and error body. Correct invalid fields before retrying; reconnect or narrow the target for authentication and permission errors. For conditional writes, reload the latest version before preparing a new request. Respect rate-limit headers and retry only when the operation’s idempotency contract permits it.
