Just to add one point, I am new to accessing web api. My task is simple to generate the bearer token to call D365 web api.

Hey John,

Try to use Grant Type as Implicit as per the documentation here ::

https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/webapi/setup-postman-environment#connect-with-your-common-data-service-environment

Please also ensure that you have Azure AD application registered in order to complete this delegated authentication.

Walkthrough: Register an app with Azure Active Directory ::

Please mark my comments as answered if this helps.

Thanks,

Thanks for the response.

I have tried with implicit grant type as well but still it asks for scope. below is the snapshot:

My app is registered in Azure Active directory with all options verfied as mentioned in the walkthrough link.

Hey John,

I did some misconfigurations on Azure AD app registration manifest file (Like "allowPublicClient": false, & "oauth2AllowImplicitFlow": true,) and reverted it back to see if the saved cookies can cause authentication issues with Azure AD and it turns out that it does as I could see an error from Azure AD though the AAD error code was different for me (AADSTS700051).

Please try to clean the cookies on Post man tool from ::

Thanks,
