| `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`.
