Google Service account authentication for API call using python

Question

Wanted to call out one GCP api from my python code, following is that method -

import google
from google.oauth2 import service_account
import google.auth.transport.requests
import requests

def get_window(self):
    credentials = service_account.Credentials.from_service_account_file(
        self.default_credentials, scopes=['https://www.googleapis.com/auth/cloud-platform']
    )
    request = google.auth.transport.requests.Request()
    credentials.refresh(request)

    # Make an authenticated API request
    request_url = "https://sqladmin.googleapis.com/v1/projects/my-projectid/instances/my-instanceid"
    headers = {"Authorization", f"Bearer {credentials.token}"}
    req = requests.get(request_url, headers=headers)
    print(req.text)

When I call this method, following is the response:

request = google.auth.transport.requests.Request()
AttributeError: module 'google.auth.transport' has no attribute 'requests'

I am using python 3.9 on my local install packages are:

pip freeze

Remove import google. That is a deprecated package that is breaking your other code. — John Hanley

Your import list shows that you have not installed the required Google Python packages. Follow the documentation to set up the Python SDK. cloud.google.com/python/docs/setup — John Hanley

I installed the google auth library and used import for right module which I missed from the last thread. — Indrajeet Gour

google.auth.transport is a package, not a module, so the correct way to import it would be

import google.auth.transport.requests

or if you prefer

from google.auth.transport import requests

For me it worked as follows:
I am using python version 3.9

import google.auth
import google.oauth2.id_token
creds, _ = google.auth.default()
auth_req = google.auth.transport.requests.Request()
creds.refresh(auth_req)

response = requests.post(
        f"{url}/route_here",
        json=payload,
        headers={
            "Content-Type": "application/json",
            "Authorization": f"Bearer {creds.id_token}",
        },
    )

To use Bearer use id_token inside creds, to use OIDC use only token
