googleauth - Class Google::Auth::ServiceAccountJwtHeaderCredentials (v1.12.0)

Reference documentation and code samples for the googleauth class Google::Auth::ServiceAccountJwtHeaderCredentials.

Authenticates requests using Google's Service Account credentials via JWT Header.

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.
