google-big-queryHow do I use a Google Big Query refresh token?

To use a Google Big Query refresh token, you need to first obtain a refresh token from the Google OAuth 2.0 Playground. Once you have the refresh token, you can use it to obtain an access token.

The following example code block uses the google-auth-library package to obtain an access token from a refresh token:

import google.auth

# Create credentials object from refresh token
credentials = google.auth.credentials.Credentials(
    None,
    refresh_token=refresh_token
)

# Get access token from credentials
access_token = credentials.token

The refresh_token parameter should be set to the refresh token obtained from the OAuth 2.0 Playground. After executing the code, the access_token variable will contain the access token. This access token can then be used to make authenticated requests to the Big Query API.
