A Python Snippet To Generate Google token.pickle From credentials.json

gen_token_pickle.py

import os
import pickle
from google.auth.transport.requests import Request
from google_auth_oauthlib import flow as google_auth_flow

# Set the path to your client_secret.json file
client_secret_file = "<PATH_TO_CREDENTIALS.JSON>"

# Check if token.pickle file exists. If not, create one.
if not os.path.exists('token.pickle'):
    creds = None
    # The file token.pickle stores the user's access and refresh tokens, and is created automatically when the authorization flow completes for the first time.
    if os.path.exists('token.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = google_auth_flow.InstalledAppFlow.from_client_secrets_file(
                client_secret_file, ['https://www.googleapis.com/auth/drive'])
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(creds, token)
