Call Phone number using whatsapp IOS

Question

Hello im new to ios development and currently need to call whatsapp phone number from my contact list fetched using Contact Framework

i have read that back then there is abid by using AdresssBook framework, the app can open specific whatsapp contact, but i also read on Whatsapp FAQ there is no abid support for URL scheme, is it still possible to call phone number or open specific chat via whatsapp ?

thank you

According to documentation I don't think you can make a call through custom whatsapp app scheme.They support currently only "text" parameter.

NSURL *whatsappURL = [NSURL URLWithString:@"whatsapp://send?text=Hello%2C%20World!"];
if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
[[UIApplication sharedApplication] openURL: whatsappURL];
}
