 * Get field configuration schemes for projects

 * Returns a [paginated](#pagination) list of field configuration schemes and, for each scheme, a list of the projects that use it.

The list is sorted by field configuration scheme ID. The first item contains the list of project IDs assigned to the default field configuration scheme.

Only field configuration schemes used in classic projects are returned.

**[Permissions](#permissions) required:** *Administer Jira* [global permission](https://confluence.atlassian.com/x/x4dKLg).
