Hello Google+ Developer,
We’re writing to let you know that as part of the sunset of the consumer version of Google+, we will be shutting down our Google+ APIs on March 7, 2019. As part of these changes, Google+ Sign-in has been fully deprecated and will also be shut down on March 7, 2019.
What do I need to know? On March 7, 2019, all Google+ APIs and Google+ Sign-in will be shut down completely. This will be a progressive shutdown beginning in late January, with calls to these APIs starting to intermittently fail as early as January 28, 2019.
What do I need to do? Please update your projects listed below by March 7, 2019 and ensure they are no longer using Google+ APIs. The data below shows which Google+ API methods your projects have recently called.
Note: If you see calls to people.get, these can be the result of using the Google+ Sign-In feature in your application, which is now fully deprecated and is being shut down. Developers should migrate from the Google+ Sign-In feature to the more comprehensive Google Sign-in authentication system.
