Google this week confirmed the date when Google+ APIs will be shut down: March 7, 2019. Until now, only the sunset month was known. The Google+ Sign-in feature has been fully depreciated and will also be shut down on March 7, 2019. Developers should migrate to the more comprehensive Google Sign-in authentication system, says Google.
The most commonly used APIs that are being shut down include:
- Google+ REST API
- Google+ Web API
- Google+ Android SDK
- Google+ Domains API
- Google+ Pages API
Google advises all developers reliant on the Google+ APIs that calls to those APIs may start to intermittently fail as early as January 28, 2019. Affected developers will receive an email, listing recently used Google+ API methods in their projects.
