REST API - DataflowUnauthorizedError - You do not have permissions to manage this dataflow

[Anonymous]

I'm following this document, https://learn.microsoft.com/en-us/rest/api/power-bi/dataflows/get-dataflow-transactions , t

So, I'm accessing this dataflow transactions endpoint https://api.powerbi.com/v1.0/myorg/groups/{groupId}/dataflows/{dataflowId}/transactions via REST API but recieved 

{"error":{"code":"DataflowUnauthorizedError","message":"You do not have permissions to manage this dataflow."}}

I was able to fetch the Dataflow lists level by using https://api.powerbi.com/v1.0/myorg/admin/groups/{groupId}/dataflows instead of https://api.powerbi.com/v1.0/myorg/groups/{groupId}/dataflows because fetching this one got 

{'error': {'code': 'DataflowInternalError', 'pbi.error': {...}}}

I used an app credentials which registered in Azure AD, which I asked the admin to enabled required permissions:

• Dataflow.Read.All

Managed to solve it!

In the question I mentioned that I can't GET https://api.powerbi.com/v1.0/myorg/groups/{groupId}/dataflows from a specific {groupId}, it is because I don't have access to that workspace, somehow I did get that workspace from /admin scope. So when I tried to access https://api.powerbi.com/v1.0/myorg/groups/{groupId}/dataflows/{dataflowId}/transactions it gives me the DataflowUnauthorizedError.

Conclusion, I had to add the registered app to the workspace and have the Data.Flow.Readall scope.

Check your token at jwt.io - it may be missing the required scope.

So just to break down, I request the token with this info

{
        'grant_type': 'client_credentials',
        'login_url': 'https://login.microsoftonline.com/{tenant_guid}/oauth2/v2.0/token',
        'scope': 'https://graph.microsoft.com/.default'
}

I believe the scope is automatically resolve?

Thank you for your response, and sorry for getting back late!

Here is the payload from jwt.io, but I don't know which field is referred to scope!
