Azure App Insights Authentication with Python Requests

Question

I'm trying to authenticate with Azure AD in order to access the Azure Insights REST API, so that I can ultimately access Azure web apps. However, the authentication example in their documentation is limited to C# and PowerShell. I am trying to do the same thing, but with the Python requests library. This is what I have so far, but I am getting a '404 not found' response back. Any ideas on how I can authenticate to the Insights API using the Python requests library?

AUTH = 'https://login.windows.net/%s' % TENANT_ID
RESOURCE = 'https://management.azure.com/'

def auth():
    s = requests.Session()

    params = {
        'grant_type': 'client_credentials',
        'client_id': CLIENT_ID,
        'client_secret': CLIENT_KEY,
        'resource': RESOURCE
    }

    response = s.post(AUTH, params=params)
    print response.url
    print response.status_code
    print response.reason

auth()

EDIT 1:

The updated auth URL fixed it. Thank you. However, I would still like to exclusively use the Python requests library to get the web apps/resource groups.

RESOURCE_VERSION = '2015-01-01'

RESOURCE_URI = 'https://management.azure.com/subscriptions/%s/resourcegroups' % (SUBSCRIPTION_ID)

s = requests.Session()
payload = {
    'grant_type': 'client_credentials',
    'client_id': CLIENT_ID,
    'client_secret': CLIENT_KEY,
    'resource': RESOURCE
}

response = s.post(AUTHENTICATION_CONTEXT, data=payload).json()
access_token = response['access_token']

s.headers = {
    'Authorization': 'Bearer %s' % access_token,
    'Content-Type': 'application/json'
}

s.params = {
    'api-version': RESOURCE_VERSION
}

response2 = s.get(RESOURCE_URI).json()
print response2

This gives me the following output

{u'error': {u'message': u"The client 'CLIENT_ID' with object id 'OBJECT_ID' does not have authorization to perform action 'Microsoft.Resources/subscriptions/resourcegroups/read' over scope '/subscriptions/SUBSCRIPTION_ID'.", u'code': u'AuthorizationFailed'}}

Based off the response, it seemed like it may be a permissions issue in my Azure app, but I've given the app all the permissions I think it has to have and it still gives me the same error message.

The authentication endpoint is incomplete. And in .Net, it is wrapped in .Net SDK, and the complete endpoint for authentication token looks like: https://login.microsoftonline.com/<tenant_id>/oauth2/token

Here is the code snippet:

from azure.mgmt.common import SubscriptionCloudCredentials
from azure.mgmt.resource import ResourceManagementClient
import requests

def get_token_from_client_credentials(endpoint, client_id, client_secret):
    payload = {
        'grant_type': 'client_credentials',
        'client_id': client_id,
        'client_secret': client_secret,
        'resource': 'https://management.core.windows.net/',
    }
    response = requests.post(endpoint, data=payload).json()
    return response['access_token']

auth_token = get_token_from_client_credentials(
    endpoint='https://login.microsoftonline.com/<tenant_id>/oauth2/token',
    client_id='<client_id>',
    client_secret='<client_secret>',
)
subscription_id = '<subscription_id>'
creds = SubscriptionCloudCredentials(subscription_id, auth_token)

resource_client = ResourceManagementClient(creds)
resource_group_list = resource_client.resource_groups.list(None)
rglist = resource_group_list.resource_groups
print rglist
