使用android / ios应用程序发送whatsapp消息

Question

What is the best way to open the WhatsApp application to send a message?

I wrote this code because I want it to open in one way through the computer browser, and otherwise by the mobile application.

First I made a condition to check where the user is accessing. If it is by some mobile device, it falls in the first condition, otherwise, it falls on the second link.

The condition of opening the application is not working, I think it may be the 'whatsapp: // ...' link can anyone help me?

        function MakeLink() {
            if ( isMobile.any ) {
                let target = 'whatsapp://send?'
                    target += 'phone='+ encodeURIComponent(phone);
                return target
            } else {
                let target = 'https://web.whatsapp.com/send?'
                    target += 'phone='+ phone;
                return target
            }

        }

    window.location.href = MakeLink();

Ps: I do not want to use the 'api.whatsapp' address because it drops to an intermediate page, increasing the client path.

Answer 1

I dont know if there is another way without api

let target = 'https://api.whatsapp.com/send?'
  target += 'phone='+ phone;

EDIT: it suddenly stopped working since yesterday.
