# GitLab API

All API requests require authentication. You need to pass a `private_token` parameter by url or header. You can find or reset your private token in your profile.

If no, or an invalid, `private_token` is provided then an error message will be returned with status code 401:

```json
{
  "message": "401 Unauthorized"
}
```

API requests should be prefixed with `api` and the API version. The API version is equal to the GitLab major version number, which is defined in `lib/api.rb`.

Example of a valid API request:

```
GET http://example.com/api/v2/projects?private_token=QVy1PB7sTxfy4pqfZM1U
```

The API uses JSON to serialize data. You don't need to specify `.json` at the end of API URL.

#### Pagination

When listing resources you can pass the following parameters:

+ `page` (default: `1`) - page number
+ `per_page` (default: `20`, max: `100`) - how many items to list per page
