Hi bao_phan ,
Thank you for reaching out to Microsoft Community.
To call your model through a Fabric Model Endpoint, you need a Microsoft Entra ID formerly Azure AD access token with the appropriate permissions. Here's how to set it up properly:Register an application in Microsoft Entra ID.
Add API permissions for Microsoft Fabric by including the scope:
https://api.fabric.microsoft.com/.default
you use it when requesting a token, This is a permission scope, used only when acquiring a token from Microsoft Entra ID (Azure AD). It tells Entra ID to issue a token that includes all application permissions the app has been granted for Microsoft Fabric.Generate the access token using the Microsoft Authentication Library (MSAL) or a tool like Postman:
For delegated access (user context), use AcquireTokenInteractive.
For application-level access (service principal), use AcquireTokenForClient along with the client secret.

If you want to call your Fabric model endpoint, you’ll need to get a Microsoft Entra token with the right permissions. The easiest way is to register an app in Entra ID, add the Fabric API permission (https://api.fabric.microsoft.com/.default), and then use MSAL to get the token. Once you have it, just pass it in your request as a Bearer token.

Mehrdad AbdollahiHi mabdollahi ,
Thanks for your response. You're right, I tried to get the token direct through the mssparkutils.credentials.getToken() and it's good to go. But now i want to call the model inside the KQL, and KQL does not support mssparkutils; let me try your option to see whether i can make it work even when in KQL (since i just write the code to test in notebook, but it must be capable to run in KQL also).
Hi bao_phan
Hope all is well on your end.
Did you win in KQL? I'd like to hear about your experience.Regards,
Mehrdad
