gar_gce_auth_default: Authenticate via gcloud's application-default login

Description

This allows you to take gcloud's application-default login token and turns it into one that can be used by R

Usage

gar_gce_auth_default(access_token, scopes, cache_file = "gcloud.auth")

Arguments

access_token

The token generated via gcloud auth application-default login && gcloud auth application-default print-access-token

scopes

The scope you created the access_token with

cache_file

Where to save the cache file of the token

Details

When authenticating on Google Cloud Platform services, if you are using services that take the cloud scopes you can use gar_gce_auth to generate authentication.

However, for other services that require a user login (such as Google Analytics API), you need a method of authentication where you can use your own email login. You have two options - create a token offline and upload it to the instance, or gcloud allows you to generate your own token online via gcloud auth application-default login && gcloud auth application-default print-access-token

This function will then take the returned access token and put it within R so it can be used as normal with googleAuthR functions.
