Using Services with Cloud Functions

API client libraries that use application default credentials automatically obtain the built-in service account credentials from the Cloud Functions host at runtime. By default, the client authenticates using the service account file specified by the GOOGLE_APPLICATION_CREDENTIALS environment variable, and uses the project specified by the GCLOUD_PROJECT environment variable. These environment variables are set automatically on Google Cloud Functions.
