Init transaction by consuming Retail Server Api using Postman throw UserAuthorizationException

Hi, we are looking to consume APIs in Postman for a client (Retail client) using MS Dynamics 365 F&O for a 3rd Party Application and have followed the following documentation:

https://learn.microsoft.com/en-us/dynamics365/commerce/dev-itpro/consume-retail-server-api

However, we are facing the following error:

Microsoft_Dynamics_Commerce_Runtime_AuthorizationFailed\",\r\n \"LocalizedMessage\": \"The user is not authorized to perform this operation

We have tried multiple steps (from a lot of sources) and continue to face this error.

Would you know how to resolve this?

I found the cause, Post should be used instead of GET in Postman ( please see screenshot bellow)

Hi Ana,

I checked the App registration created by the client on Azure portal and I modified them to respect the steps in learn.microsoft.com/.../consume-retail-server-api

But always I receive the same error when trying to init transaction,

App registration for Retail server :

App registration for the client :

the app registred in Finance and operations identy provider

the error on Postman

and here I can get response ( I use the same Access token)

I need help please!

Regards

Hi Ana,

Sorry for the delay, but I still wait for the client to give me access to check the app registration in Azure portal, But what is strange is that I can consume Retail server APIs related to product like Search Product By Text without receiving any errors, it only blocks when I do init transaction in order to start an empty transaction to be able to add products to this transaction after that.

knowing that I use the same Azure credentials App provided by the client in the two scenario
