# Implements the following CURL command:

# curl -H "Authorization: Bearer YOUR_ACCESS_TOKEN" https://www.googleapis.com/oauth2/v3/userinfo

# Use the following online tool to generate HTTP code from a CURL command
# Convert a cURL Command to HTTP Source Code

# Adds the "Authorization: Bearer YOUR_ACCESS_TOKEN" header.
