CX CASH Integration Services
There is an OData API endpoint for the SUITE cx CASH application which is not enabled by default. It needs to be enabled by the IPS server Administrator using the application Service setting 'IntegrationServicesIsServiceEnabled'. (See the PlanningSpace Deployment Guide for details.)
The resource path for the API is '/PalantirCash/data/v1'.
You can connect to this API, and use OData query language, in the same way as for the other OData APIs. Also you can connect to it using client tools such as Excel Power Query and Spotfire.
API reference information can be found at: PalantirCASH OData API Reference.
