Hi Everyone,
 
I have followed couple of blogs for creating Custom Service, Postman create token

https://dynamics365musings.com/setup-postman-to-call-d365-data-entities/
 
 
Token generated successfully but while pulling data from Customer Webservice it throws me error
 

{
    /Message/: /Authentication failed./,
    /StackTrace/: null,
    /ExceptionType/: /System.InvalidOperationException/
}

Attaching the screenshot for the same.

Let me know what i missed ?

Thanks all!

    Hi Anthony,
     
    I was able to generate the access token previously
     
    when i tried to get any standard API it shows the same error.
     
    In the Azure Active Directory F&O  i have set the client id and set the user as admin.
    in App registration all the API permission is given with respect to D365 
     
    The same webservices if i open it from browser it works but from postman it stills throw the same error.
     
    Is it some issue with postman or any permission related or any credentials that I failed to add.
     
    Let me know.

    If you get the same response using my postman project - share your App reg permissions and D365 Entra ID Applications in the System Admin Menu

    Hi,
     
    I have a working public postman project with customer examples, try it out and check the requests against your own:

    Hi CU,
     
    Follow my blog article and you should be able to get a token successfully and call odata.
     
    If you still find any issues, then please let me know.

    Hi,
     
    Can you share the headers tab when you 're calling the entity?
     
     
    Thanks,

    Hi Judy

    i checked my client id and client secret and token is getting created successfully.
     
    I tried to get the customer -API using bearer token and paste that value


    It still shows the same error.
     



    Thanks

    Hi, in Access token request, you would have mentioned a CLIENT ID. This has to be set up in FO as well. Go to System Administration -> Set up -> Azure active directory.
    Hope it helps.
    Best Regards,
    Judy
