Collections of resources are always ordered. Therefore each model defines a default sort order. Usually this is ascending by name (e.g. for Services) or descending by id (e.g. for Requests).

To change the ordering provide the ?sort= parameter. Multiple fields must be separated with a comma. Fields are sorted in ascending order, unless they are prepended with a minus sign.

$ curl https://api.itrp.com/v1/requests?sort=-status,impact,-id

Only a subset of the available fields may be used. If a different field is provided a Bad Request response will be returned. The documentation on that specific resource defines the sortable fields.

$ curl https://api.itrp.com/v1/requests?sort=problem
Status: 400 Bad Request
