How to use integration via Google API for OpenSource application?

Question

Google

There is an application for a small circle of people, we are finalizing it.
I would like to implement optional integration with Google Calendar and Google Tasks for it, but the keys for the Google API are issued for one application.
What if the Open Source application and it will be used by different users who will link their Google accounts? Get an API key for one account that this application will be "listed" as?

Answer 1

these are different things - in order to access via OAuth through your application, it must receive confirmation - client_id/client_secret are used to form a request for users. In general, read the OAuth2 specification or the description for Google adapters https://code.google.com/archive/p/oauth/
