## Approve Merge Request

>**Note:** This API endpoint is only available on 8.9 Starter and above.

If you are allowed to, you can approve a merge request using the following
endpoint:

```
POST /projects/:id/merge_requests/:merge_request_iid/approve
```

**Parameters:**

| Attribute           | Type    | Required | Description             |
|---------------------|---------|----------|-------------------------|
| `id`                | integer | yes      | The ID of a project     |
| `merge_request_iid` | integer | yes      | The IID of MR           |
| `sha`               | string  | no       | The HEAD of the MR      |
| `approval_password` **(STARTER)** | string  | no      | Current user's password. Required if [**Require user password to approve**](../user/project/merge_requests/merge_request_approvals.md#require-authentication-when-approving-a-merge-request-starter) is enabled in the project settings. |

The `sha` parameter works in the same way as
when [accepting a merge request](merge_requests.md#accept-mr): if it is passed, then it must
match the current HEAD of the merge request for the approval to be added. If it
does not match, the response code will be `409`.
