I am able to call a get Operation on the PurchaseOrderHeadersV2 entity using Postman client as a part of a collection in which previously we could get a bearer token as well before the get Operation is called.
However , I am unable to call a POST operation on the same entity to create a PO with below raw text (in JSON format) getting 403 Forbidden error from the FnO Server.
Can you check if you have added the Client Id in 'Azure Active Directory Applications' in F&O.
Rather than an import, try an export first for 'CustomerGroup' and you will get a clue if the issue exists in the set up.
Hi DebasisSamantray,
There are many causes of such errors, and they generally happen if the accessToken is incorrect or the registration is incorrect on the Dynamics side. Please check the Prerequisites and the steps to query OData by using Postman:
Does FnO expects the JSON request in a different format or any additional information in the request?
