Hello,
I am trying to get the token from the API using the Password Flow following this tutorial.
I am not able to successfully call the API and I receive
{"error":"access_denied","error_description":"Unauthorized"}
I am following the tutorial and I am not sure why this is not working. Any help on this?
Hi @giorgio.zorzi,
Welcome to the Auth0 Community!
Can you please share the request (with any sensitive info removed) that is causing this error?
Hi @dan.woda,
Thank you for your reply!
I am using python following the script from the link. Here it is
import http.client
import requests
url = "https://something.eu.auth0.com/oauth/token"
client_id = 'CLIENT_ID'
client_secret = 'CLIENT_SECRET'
username = 'test_user@email.com'
password = 'password'
api_identifier = '/api'
scope = "openid profile email"
conn = http.client.HTTPSConnection("")
headers = {'content-type': "application/x-www-form-urlencoded"}
data = {
"grant_type": "password",
"username": username,
"password": password,
"audience": api_identifier,
"client_id": client_id,
"client_secret": client_secret,
}
resp = requests.post(
url=url,
headers=headers,
json=data,
)
print(resp.text)
Can you confirm that the password grant setting is turned on you application settings?
And make sure the app is authorized to access the API you are declaring in the audience param.
Yes, I made sure that both steps are as you described
Can you try removing the audience param for the sake of debugging and see if that is causing this error?
Still getting the same error
Great, we can rule that out.
Have you enabled the connection? Also, can you DM me your tenant name and the name of the client?
I figured out the problem.
I was supposed to use
resp = requests.post(
url=url,
headers=headers,
data=data,
)
instead of
resp = requests.post(
url=url,
headers=headers,
json=data,
)
BTW, I had to change the python library from http (the one used in the tutorial) to requests because that was erroring out for me with

I suspect that this is a linux-specific error
Thanks for posting your solution!
