API is not accessible for application: Using Python to call Admin API and get App and DatasetUsers

[D_Lav]

Hi, 

I have created a synapse workspace with a lakehouse and notebooks that i use to retrieve Power BI information from my tenant. 

This include apps, workspaces, datasets, activity etc. hovewer, i want to retrieve dataset users and app users aswell. 

To access these APIs i have created an App in my Azure portal which i have added in AD group and provided access to the following settings in Admin Portal, 

1. Allow Service principals to use Power BI APIs

2. Allow Service principals to use read-only admin APIs

3. Enhance admin APIs responses with detailed metadata

4. Enhance admin APIs responses with dax and mashup expressions

for this i tought i could use the following APIs 

https://learn.microsoft.com/en-us/rest/api/power-bi/admin/datasets-get-dataset-users-as-admin

https://learn.microsoft.com/en-us/rest/api/power-bi/admin/apps-get-app-users-as-admin 

What i do is that i first retrieve dataset IDs (this works) and then loop over these IDs with this Python code inside my notebook.

#Get a list of datasets

uri_datasets = 'https://api.powerbi.com/v1.0/myorg/admin/datasets?$top=5'

response_datasets = requests.get(uri_datasets,headers=headers)

#to loop over datasetIds and get dataset User from this API - Admin - Datasets GetDatasetUsersAsAdmin

if response_datasets.status_code == 200:

    result = response_datasets.json()['value']

    datasetUserList = []

    for item in result:

        uri_datasets = f'https://api.powerbi.com/v1.0/myorg/datasets/{item["id"]}/users'

        response_datasetsUser = requests.get(uri_datasets,headers=headers)

        df=pd.json_normalize(response_datasetsUser.json())

        df['dataset_id']=item['id']

        datasetUserList.append(df)

df_concat = pd.concat(datasetUserList)

df_concat = df_concat.reset_index(drop=True)

df_json = df_concat.to_json()

If i try to print out df_json i get the following message and no user information is returned. 

{"Message":{"0":"API is not accessible for application","1"

i looked at the documentation and saw this under Required Scope

Tenant.Read.All or Tenant.ReadWrite.All

Relevant only when authenticating via a standard delegated admin access token. Must not be present when authentication via a service principal is used.

i have no idea what it means with standard delegated admin access token so if anyone could help me out and get this Python code running against this API i would be very glad!

Edit: I solved this, it was a human error, when using chatGPT to clean up my code it was helpfull enough to change my API from Admin/ to regular. changing it back to admin API URL for Power BI solved the problem:)
