# Suggest Changes API **(FREE)**

This page describes the API for [suggesting changes](../user/project/merge_requests/reviews/suggestions.md).

Every API call to suggestions must be authenticated.

## Applying a suggestion

Applies a suggested patch in a merge request. Users must have
at least the Developer role to perform such action.

```plaintext
PUT /suggestions/:id/apply
```

| Attribute | Type | Required | Description |
| --------- | ---- | -------- | ----------- |
| `id` | integer | yes | The ID of a suggestion |
| `commit_message` | string | no | A custom commit message to use instead of the default generated message or the project's default message |

```shell
curl --request PUT --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/suggestions/5/apply"
