We’ve recently updated our endpoint documentation with more details about which attributes you can use to filter your results and which related resources can be included. We’ve also got a new documentation page about filters with some examples of how they’re formatted. Filters help you reduce the redundant or irrelevant data you might get when you’re querying one of the worktag resources. The most common use is to filter for only records related to your campus (aka company).
Includes can be used to reduce the number of separate calls to the API. Each resource endpoint page now has details about which resource types can be included. At the moment, only driver worktags (gifts, grants, programs, and projects) have related records.
