For what it’s worth, I’ve received a second email from Google with the following:
Dear Developer,
Earlier this week we sent you an email related to your projects that will be impacted by the Google+ API shutdown, which also affects requests for Google+ OAuth scopes.
The email listed that one or more of your projects are requesting the “plus.me” scope, and would thus be affected. We would like to clarify that only projects directly requesting the “plus.me” scope are affected . This scope may have been listed in some emails, even if not directly requested by your project. We apologize for any confusion caused.
If you are directly requesting the “plus.me” scope, any other Google+ OAuth scopes, or making any Google+ API calls, please ensure that you remove these requests from your project before March 7, 2019 .
To see if your project is directly requesting the “plus.me” or any other Google+ OAuth scopes:
- If your project is written in Google Apps Script, you can view which scopes your project is requesting by reviewing your project properties in App Script Editor.
- If your project is not written in Google Apps Script, please check your code for references to “plus.me” in OAuth scope requests. We recommend that you review projects using any 3rd-party libraries that support sign-in or social functionality, as these may also be affected by the shutdown.
Thanks for being a valued Google+ Developer.
Sincerely,
The Google+ API team
Considering we don’t have any Google Apps Script applications and we don’t have any references to plus.me anywhere in our code, this reaffirms that there must be something somewhere in Auth0 that references it. Hopefully you get some good news from the team.
