Facing issue with AppDynamics API REST call authentication

[CommunityUser]

Hi ,
I am unable to access AppDynamics REST API.
If I write a sample code using the python client

from appd.request import AppDynamicsClient
c = AppDynamicsClient('URL','group','appd@123')
for app in c.get_applications():
print app.id, app.name

It works fine .

But if I do a simple REST call like the following
I get the following response

import requests
usr =<uid>
pwd =<pwd>
url ='http://10.201.51.40:8090/controller/rest/applications?output=JSON'
response = requests.get(url,auth=(usr,pwd))
print 'response',response

response <Response [401]>
Am I doing anything wrong here ? In case anybody has faced such issue please let me know

Hi Ayan,

Could you please  verify the password is correct by login in to the controller with the credentials. As  401 Unauthorized

Error means the page you were trying to see needs valid user ID and password.

Thanks,
