We're using Google Analytics API in our application and perform actions (read data) on behalf of our users (we get their tokens via OAuth2). We use a client id and client secret to authorize our Google API project (application).
The problem is that we're unable to reach this project in Google's developer console, because the user in our Google App account who created this project was deleted. Regardless, the Google API still works (we have the key and the client secret) but we're unable to reach it in the admin section in the browser, but we can't access it because the owner was deleted.
What are the options to recover access to this API project? Is it possible to transfer ownership of this project using Google API? It's running in production so we can't afford to generate a new API project.
Is it perhaps possible to generate a new API project by keeping all our users consents (they authorize their accounts using an authorization popup in our web app)?
EDIT: it's also possible the user still exists, but we don't know who's the owner. Is it possible to retrieve this info using the app's api key/secret?
