Power BI Rest API wont accept Application Token
- Anonymous4 years ago
Solution found thanks to SpartaBI !
1. Go to App registration -> New registration
2. Give your app a name and use the default settings
3. Create a secret, and make sure you copy the right value
4. Copy the ClientId & TenantIdNo need to do anything else with the app config.
Just add "MyNewApp" to the AAD security group, wait for a couple of minutes, then try your code.Then for running a Non-Admin API call, the App needs added into the Workspace Permissions you want to read from.
You do not need to add any delegated permissions to the app.
In order to allow a service principal access no non-admin APIs, it must have the same dataset/workspace permissions as any other user. For example- you can add the service principal as a member of a workspace.This is exactly the purpose of the other setting in the Admin Portal.
It defines the service principals whose permissions are being managed by the Power BI Service itself.
We tried this out. No luck. Created a Security Group, Service Principle account, added it into the Group, added the SP to Own the Application, and added the Group onto the Power BI Admin portal in those API settings.
You said the M-code worked for you, just to confirm, was it both the GET Access Token and the API Call for Workspaces and Expanded info?
Besides doing this, I'm really stuck now. What else makes sense to anyone?
Hi Anonymous,
Both the GET Access Token and the API Call for Workspaces work for me.
I'm not sure what you mean by "adding the SP to own the application".
I suggest you'll create a new app. From your opening post, I gather you grant it permissions- which is redundant. To create an app do this:
1. Go to App registration -> New registration
2. Give your app a name and use the default settings
3. Create a secret, and make sure you copy the right value
4. Copy the ClientId & TenantId
No need to do anything else with the app config.
Just add "MyNewApp" to the AAD security group, wait for a couple of minutes, then try your code.

My comment about making the SP an Owner was because your picture of the App Registration that showed your SP account was an Owner on the application, I thought that was something also necessary for this to work. We can move on from that now.
Are you saying that you don't need to grant the Power BI Service API Permissions on this App Registration though?

Hi SpartaBI ,
Can you clear one thing up for me, how are you adding the App to an AAD security group?

Hi Anonymous,
You do not need to grant the Power BI Service API Permissions to the App.
Those permissions are used to allow user delegation (i.e., the app acts on behalf of a user account).
When you use "grant_type = client_credentials", you are using the permissions granted to the app's service principal.
Adding the app's service principal to the security group:
Go to your AAD
Find the security group
Choose "Add members"
Search for the service principal (same name as the app) and add it- Anonymous4 years agoNot applicable
Hi SpartaBI
Thank you for your patience and help!
We have 95% Success! We created a New App (with no API Permissions) and added both into the Security Group we created just for SP's.
*I think my confusion was that a Service Principle exists for the App Registration, and I was thinking it had to somehow use a physically created Service Principle user we created.
Our 1st App Registration that had the API Permissions, but was otherwise identical to the 2nd new App Reg, still wouldn't work after adding into the Security Group.
But at least the 2nd App is working in the API.
I said 95% because it works on all of my admin/ API calls, but it won't work on a non-Admin call. I have one trying to get the refresh schedules across the list of WorkspaceIDs and that says Access Forbidden. This same function structure works for another one that gets all Users off the Apps because thats an admin/ call.
Thoughts??
I'm thinking we need to now add in the API Permissions that the non-Admin calls get treated as Delegated and will need those added? I'm also hoping by adding those permissions, it wouldn't break whats working and cause us to have to recreate again (just saying this because I know how querky MS can be sometimes).
*FYI, yes that previous post would be at least part of the solution to this posting, but I'm hoping we figure out how to get this non-Admin API working, then consolidate the answers into 1 post and mark that as the solution. This can hopefully help a lot of people.
