Configure Google Service Account Authentication for REST

See more REST Examples

Demonstrates Rest.SetAuthGoogle, which associates an AuthGoogle provider so Chilkat supplies a Google OAuth 2.0 bearer token on each request. The provider is configured with a service account JSON key and the required OAuth scope.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.
