Skylight has a powerful and easy-to-use web user interface (UI), and this UI is an ideal starting point for new Skylight users.  

For users who want to integrate data from Skylight with other tools (including locally developed systems), the Skylight application programming interface (API) provides an alternate way to access data from the platform.  

The API allows Skylight data to be treated as input to another platform so end-users can leverage their knowledge of a platform they already know.

The Skylight API is built on the GraphQL query language.  If you're not already familiar with GraphQL, their website provides helpful learning resources.

Schema documentation for the Skylight API can be found here.  The documentation includes examples of API authentication, valid request parameters, etc.
