Open whatsapp on iOS with a new phone number pre-populated

I know that there is a scheme for communicating with whatsapp:

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

But I can not find how to open whatsapp with a phone number that was not there before.

This is for the contatc us page, and if I can only open whatsapp and cannot prefill the phone number, it is useless. I need to contact whatsapp ...

Is there something I'm trying to do?

You can find documentation on this whatsapp API above answer. Adding a few more points to that based on my own trial version:

For direct communication with a specific contact you need to follow this contact. ABID is the parameter that is automatically generated by the system when a contact is saved. Therefore, if you do not have a number stored in your contact, so you cannot open it from your application.

There is one workaround that I used. When your application is first downloaded to the device, you save the contact number in the address book. when the number is saved successfully, you will get the ABID in the opposite direction. You can use this ABID to call messaging with this contact.

 NSURL *whatsappURL = [NSURL URLWithString:@"whatsapp://send?abid=123&text=Hello%2C%20World!"];

If someone is looking for a version of Swift

 static func triggerWhats(_ vc:UIViewController){ let msg = "Hello! I have a question" let urlWhats = "whatsapp://send?phone=+6599999999&text=\(msg)" if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed){ if let whatsappURL = NSURL(string: urlString) { if UIApplication.shared.canOpenURL(whatsappURL as URL) { _ = UIApplication.shared.open(whatsappURL as URL, options: [:], completionHandler: nil) } else { // Cannot open whatsapp ViewUtil().popAlertView(vc, title: "WhatsApp Support", message: "Please WhatsApp us at +65999999 if you have any questions", option: "Ok") } } } }
