Contact-tracing API, a recent update to Google’s Android and Apple iOS, allows apps to monitor your movement and warn you of Covid-19 infections around you. The APIs are part of a global joint initiative by Google and Apple and enable contact tracing in order to warn about potential corona infections. Over 20 countries are using the APIs developed by Apple and Google in their contact-tracing apps. Now, both Google and Apple have reportedly contacted the Indian govt for linking APIs to Aarogya Setu app that is widely used in the country. However, an official said that Aarogya Setu has an in-built contact-tracing API and thus may not require this API.
