ServiceAccountJwtAccessCredentials
class ServiceAccountJwtAccessCredentials extends CredentialsLoader (View source)
Authenticates requests using Google's Service Account credentials via JWT Access.
This class allows authorizing requests for service accounts directly from credentials from a json key file downloaded from the developer console (via 'Generate new Json Key'). It is not part of any OAuth2 flow, rather it creates a JWT and sends that as a credential.
