Dear Nirav Merchant & NAGARAJKMAR SUBRAMANIAN As per my knowledge, currently Whats App is not having any authenticated API to integrate with any other application. How ever some guys are doing integration with .Net and other software. But I think it is not trusted as it is not provided by Whats App team.
