Partner Center rest api 401 error

Question

I tried to use partnercenter api to get the billing details. But API call return 401 error code. the details provided on partnercpi are correct one and its working fine If I give it as input for Subscription API.

URL : https://api.partnercenter.microsoft.com/v1/customers/<Customer-tenant-ID>/subscriptions/<Subscription-ID>/usagerecords/resources

Can you suggest what can be the reason for the error.

Reference link : https://msftstack.wordpress.com/2016/01/05/azure-resource-manager-authentication-with-python/

Here is my python code.

import adal
import requests


application_secret = 'asdq23Y+tRgEspFxQDPasd'
application_id = '523129-1267b-123'


authentication_endpoint = 'https://login.microsoftonline.com/'
resource  = 'https://management.core.windows.net/'

context = adal.AuthenticationContext(authentication_endpoint + tenant_id)
token_response = context.acquire_token_with_client_credentials(resource, application_id, application_secret)

access_token = token_response.get('accessToken')


endpoint = "https://api.partnercenter.microsoft.com/v1/customers/<customer tenant ID>/subscriptions/<sub-id>/usagerecords/resources"


headers = {"Authorization": 'Bearer ' + access_token}

json_output = requests.get(endpoint,headers=headers)
print json_output

Output Response:

<Response [401]>

Is this method not fit for partnerapi usage collection ?. If not pls suggest alternate option. Thanks in advance.

Answer 1

401 is because partner center does not work with just the token from Azure AD.

The actual Auth workflow

1. Get a Token from Azure AD.
2. Use that token to get an access token from PartnerCenter.
3. Use this token to communicate with the partner center REST APIs.
