send message on whatsapp number using whatsApp API

Question

As I need to send message on user's whatsapp number so I have downloaded WhatsApp API from nuget packages. and also I implemented code according to that. But after so many search I found that I need to register mobile number to get password...using WART but I think this application is not working and not able to get password from WhatsApp.

So if anyone implement this feature of sending message on whatsapp number in Asp.net c# then please update me how to do this using WhatsApp Api.. even I don't know whatsapp is provide any API or not.

I have tried with below code...but I need password before that..

            string fromMob = "919xxxxxxxxx";
            string toMob = txtMobileNo.Text.Trim();
            string msg = "This is first WhatsApp Message Whatsapp API";

            WhatsApp wa = new WhatsApp(fromMob, "RequiredPassword", "SD", false, false);

            try
            {
                wa.OnConnectSuccess += () =>
                {
                    wa.OnLoginSuccess += (phoneNumber, data) =>
                    {
                        wa.SendMessage(toMob, msg);

                    };

                    wa.OnLoginFailed += (data) =>
                        {
                            msg = "Login Failed" + data;
                        };
                };

                wa.OnConnectFailed += (ex) =>
                    {
                        msg = "Connection Failed" + ex;
                    };
                wa.Connect();
            }
            catch { }

It's definitely doesn't work. I think the only way is to use WhatsMate or similar service. But I can't say if they work for sure. Haven't checked yet. — yurart, Apr 29 '18 at 19:04

WhatsApp Business API is live now. Please refer this link for detailed information.

The WhatsApp Business API Client supports a subset of the features provided by the WhatsApp applications you already know from Android, iOS, Web and other platforms including end-to-end encryption. The difference is that this application can be deployed on a server, providing a local API that allows you to programmatically send and receive messages and integrate this workflow with your own systems (CRMs, customer care, etc.).

Please note that if you use anything other than the official WhatsApp Business API or other official WhatsApp tools, we reserve the right to limit or remove your access to WhatsApp as this violates our policies. Please do not use any non-WhatsApp authorized third-party tools to communicate on WhatsApp.

Referring to Whatsapp API documentation,

In the documentation, you can go API docs of send message, read message, set webhook APIs

This is not owned by whatsapp this is third party I think. – Jaydeep Mor Sep 14 '20 at 12:50
It is not working since 2021. There is guy who mantains actual list of unnoficial whatsapp api providers. You can find the list here https://github.com/yredsmih/whatsapp-blacklisted-providers – the one Aug 01 '23 at 09:40
