Returns project fields metadata, including out-of-the-box and custom fields. Use the field ID in fields and filters when calling the <a href="/reference/post_attendance-projects-search" target="_blank">project search endpoint</a>.

The field can be returned on search and set on create/update, but it is not supported as a search filter.</p> <p><b>Important Note: Custom fields of the following types are not supported via the API: <ul><li>Multi-select list</li> <li>List</li> <li>Document</li> </ul></b></p>
