## Protect repository branch

Protects a single project repository branch. This is an idempotent function,
protecting an already protected repository branch still returns a `200 OK`
status code.

```
PUT /projects/:id/repository/branches/:branch/protect

curl -X PUT -H "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v3/projects/5/repository/branches/master/protect

| --------- | ---- | -------- | ----------- |
| `id` | integer | yes | The ID of a project |
| `branch` | string | yes | The name of the branch |

Example response:

```json
{
  "commit": {
    "author_email": "john@example.com",
    "author_name": "John Smith",
    "authored_date": "2012-06-27T05:51:39-07:00",
    "committed_date": "2012-06-28T03:44:20-07:00",
    "committer_email": "john@example.com",
