Business Catalyst has a push notification for new customer inquiries that sends a POST request with the object ID, e.g.ObjectID=1234567&ObjectType=2001
The answer to this question say to use the SOAP API(Legacy) to request the details of the case.
Is there a way to do this using the new Rest API?https://docs.worldsecuresystems.com/reference/rest-apis/index.html
There is no documented method for a cases or case endpoint.
If not, the only solution wil be to mix the API calls being used .
Some of the API's haven't been updated to v3 yet (REST) so unfortunately you will still need to use the SOAP endpoint for the Cases API.
