PowerBI Embedded - Capacities Update Rest API

[nicm-cc]

Hi There,

I am trying to programmatically scale up/down my embedded capacity using this rest api (Capacities - Update - REST API (Azure Power BI Embedded) | Microsoft Learn). When I test the API within the documentation, it works as intended but trying to call the API from within my application I cannot get past the permissions error.

My service principle application registration has all the permissions for powerbi granted.

In my application, I am obtaining an access token using my client credentials but when using that access token to call the update capacities api, I get this error:

b'{"error":{"code":"AuthorizationFailed","message":"The client \'xxxxxx\' with object id \'xxxxxx\' does not have authorization to perform action \'Microsoft.PowerBIDedicated/capacities/write\' over scope \'/subscriptions/xxxxxx/resourceGroups/PowerBI/providers/Microsoft.PowerBIDedicated/capacities/ccpowerbi\' or the scope is invalid. If access was recently granted, please refresh your credentials."}}'

Which specific permissions am I missing? I see in the documentation that this is the required scope but not sure exactly how to auth with this scope:

Thanks in advance

Hi @nicm-cc ,

According to the error message, it indicates that there is no necessary permissions to call that REST API. Here are a few things you could check:

• Enable Allow service principals to use Power BI APIs
• Add the service principal to your workspace
• Authorization Header: Check if the authorization header is listed correctly. Make sure there are no typos.
• Token Expiry: The Azure AD authorization token might have expired.
