Is it possible to access GCP resources using api without a user interaction

Question

Everywhere the REST API needs a user interaction for authentication. Is there a possible way to access the GCP resource without an interaction from user.?

I'm asking in general, i have no specific application.

Thanks!

Answer 1

yes that's totally possible.

You'd have to create a service account representing your application (executed as the cron job) and in your application you'd authenticate the REST API calls using that service account's credentials.

A service account is a Google account that represents an application, as opposed to representing an end user.
