WhatsApp to support Do not Disturb API for missed calls

WhatsApp, the world's most popular instant messaging platform, is working on a new API (Application Program Interface) for Android. The feature will let users know when they miss a call during 'Do not Disturb' mode. It was spotted by WABetaInfo in the new WhatsApp beta for Android 2.22.21.7 update. The feature was first rolled out to iOS beta testers back in June.
