The custom data source API is a communication protocol that allows retrieving already aggregated data from a server to Flexmonster Pivot.
To fetch the data from the server, Flexmonster sends POST requests to the API endpoints in JSON format.
|<url>/handshake||The first request to establish a connection between the client and server sides.|
|<url>/fields||Request for all fields with their types.|
|<url>/members||Request for all members of the field.|
|<url>/select||Request for data; can be for pivot table, flat table, and drill-through view.|
