How i get WhatsApp abid to compose a message to a specific user ? i want to send a text message when i select a contact in my app.

This is my code:

NSURL *whatsappURL = [NSURL URLWithString:@\"whatsapp://send?abid=XXX\"];
         if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
             [[UIApplication sharedApplication] openURL: whatsappURL];
         }

Two recent solutions (July 2017)

1. WhatsApp 'Click to Chat' API feature must work on all devices:

2. And, this other schema (for href links) seems to be working also:

   whatsapp://send?text=MESSAGE&phone=+NUMBER&abid=+NUMBER
