......@@ -151,7 +151,53 @@ When listing resources you can pass the following parameters:
- `page` (default: `1`) - page number
- `per_page` (default: `20`, max: `100`) - number of items to list per page
[Link headers](http://www.w3.org/wiki/LinkHeader) are send back with each response. These have `rel` prev/next/first/last and contain the relevant URL. Please use these instead of generating your own URLs.
### Pagination Link header
[Link headers](http://www.w3.org/wiki/LinkHeader) are sent back with each
response. They have `rel` set to prev/next/first/last and contain the relevant
URL. Please use these links instead of generating your own URLs.
In the cURL example below, we limit the output to 3 items per page (`per_page=3`)
and we request the second page (`page=2`) of [comments](notes.md) of the issue
with ID `8` which belongs to the project with ID `8`:
```bash
curl -I -H "PRIVATE-TOKEN: 9koXpg98eAheJpvBs5tK" https://gitlab.example.com/api/v3/projects/8/issues/8/notes?per_page=3&page=2
```
The response will then be:
```
