I am trying to access the API based web service created in Microsoft Dyanamics D365 for Operation and my service is having the single parameter. when i try to pass the parameter it is throwing below error. I am using Oauth2 token when i call service without parameter it is working as expected, but when i call a simple service with parameter i am getting error marked in title. Kindly help.

It could be the exception from Microsoft Dynamics 365, not from the SxS API. To test the SxS API with postman, please follow steps in the Side by Side Integration API Quick Start.
