It seems like Google SDK wants to open the browser for the user to authenticate, but there's no browser in AWS Lambda. Is there another way to authenticate without opening the browser? If i use https://developers.google.com/identity/protocols/OAuth2ServiceAccount#jwt-auth will it work?Anyone has any helpful links/ sample that I can use? I'm not experience programmer really appreciate your help, thank you in advance.

Answer 1

You can use a service account key in order to avoid using a browser.

A service account is a special type of Google account intended to represent a non-human user that needs to authenticate and be authorized to access data in Google APIs.
