Python requests OAuth2 token 401 in Genesys Cloud staging

Hey everyone. I’m trying to automate some data pulls from our staging environment using Python and the requests library. We’ve been using the Embeddable Client App SDK for our desktop widgets, but for this backend script, I need a raw access token to hit the Analytics APIs.

I’m using the Client Credentials flow since this is a server-to-server call. Here’s the setup:

  • Environment: Genesys Cloud Staging (US-West-1)
  • Python 3.9
  • requests 2.31.0

The code looks pretty standard to me. I’m hitting /oauth/token with the client ID and secret.

import requests

url = 'https://api.mypurecloud.com/oauth/token'
headers = {
 'Content-Type': 'application/x-www-form-urlencoded'
}
data = {
 'grant_type': 'client_credentials',
 'client_id': 'my-client-id',
 'client_secret': 'my-client-secret'
}

response = requests.post(url, headers=headers, data=data)
print(response.status_code)
print(response.json())

The response comes back with a 401 Unauthorized. The JSON payload says "error": "invalid_client".

I’ve double-checked the credentials. They work fine when I use the Postman collection provided in the docs. I even tried encoding the client_id and secret in the Authorization header as Basic Auth, just in case, but that gave the same 401 error.

Is there something specific about the staging environment that requires a different endpoint? I noticed the production docs mention api.mypurecloud.com, but maybe staging uses a different host? Or is it possible my client credentials are scoped incorrectly for the client_credentials grant type?

I’ve tried adding audience parameter but that just makes it worse. The docs aren’t super clear on the exact payload format for Python requests specifically. Most examples show curl or JS.

Any ideas what I’m missing? I’ve been staring at this for two hours and it’s driving me nuts. The SDK handles auth automatically, so I don’t want to reinvent the wheel, but I need the token for this specific script.
