Hi, Please see my response below:
1. You can get a refresh token by following the instructions provided in this guide <https://github.com/googleads/googleads-dotnet-lib/wiki/API-access-using-own-credentials-(installed-application-flow)#step-2---setting-up-the-client-library> for the application type you have chosen. Please note that there is currently a limit of 50 refresh tokens per user account per client. If the limit is reached, creating a new token automatically invalidates the oldest token without warning. 2. I'm afraid you'll not be able to identify if a user has been authorized previously. You could consider including the "email" scope <https://developers.google.com/identity/protocols/googlescopes#google_sign-in> when you generate the refresh token, so that you'll be able to get the email address of the user authorized your application and store the refresh token and email address in you database. This way, you'll be able to identify if a user has previously authorized or not.
