OData: One of the benefits of OData is that it enables broad integration across products.
Batch data API with recurring integration enables the exchange of documents or files between finance and operations apps and any third-party application or service.
OData: The Excel Data Connector app interacts with Excel workbooks and OData services that are created for publicly exposed data entities.
Custom service: In finance and operations apps, request that a developer create a custom service to calculate the physical on-hand inventory for a given item. In the scheduling application, make a real-time call to a custom service endpoint, through either SOAP or REST, to retrieve inventory information for the selected item.
You would set up a recurring integration for this scenario.
