Mobile website “WhatsApp” button to send message t

问题:

A mobile website can be customized to allow users to share a pre-filled message in WhatsApp to a manually chosen contact. As given here it is done using Custom URL Scheme. An example:

<a href="whatsapp://send?text=Hello%20World!">Hello, world!</a>

To call a particular number we use:

<a href="tel:[phone]">Call</a>

Similarly, can we send a WhatsApp message to a specific number (or at least open the chat) without user choosing the phone number manually rather it will be one of the predefined parameters/attribute values?

This can be easily done now! You just need to use this format:

<a href="https://api.whatsapp.com/send?phone=whatsappphonenumber&text=urlencodedtext"></a>

UPDATE-- Use this from now(Nov-2018)

<a href="https://wa.me/whatsappphonenumber/?text=urlencodedtext"></a>

Use: https://wa.me/15551234567

Don't use: https://wa.me/+001-(555)1234567

To create your own link with a pre-filled message that will automatically appear in the text field of a chat, use https://wa.me/whatsappphonenumber/?text=urlencodedtext where whatsappphonenumber is a full phone number in international format and URL-encodedtext is the URL-encoded pre-filled message.

Example:https://wa.me/15551234567?text=I'm%20interested%20in%20your%20car%20for%20sale

To create a link with just a pre-filled message, use https://wa.me/?text=urlencodedtext

Example:https://wa.me/?text=I'm%20inquiring%20about%20the%20apartment%20listing

After clicking on the link, you will be shown a list of contacts you can send your message to.

On android, you can try

href="intent://send/[countrycode_without_plus][number]#Intent;scheme=smsto;package=com.whatsapp;action=android.intent.action.SENDTO;end

replace [countrycode_without_plus][number] with the number,

WhatsApp is now providing a much simpler API https://wa.me/ This isn't introducing any new features, just a simpler way to execute things. There's no need to check for user agent while implementing this API as it will also work with native apps as well as the web interface of whatsapp (web.whatsapp.com) on desktop.

This can be used in multiple use cases

• A Click to chat button : Use https://wa.me/whatsappphonenumber to open a chat dialog with the specified whatsapp user. Please note that the whatsappphonenumber should be a valid whatsapp number in international format without leading zeros, '+', '-' and spaces. e.g. 15551234567

  <a href="https://wa.me/15551234567">Whatsapp Me</a>

• A Share this on whatsapp button : Use https://wa.me/?text=urlencodedtext to open a whatsapp contact selection dialog with a preset text. e.g.

  <a href="https://wa.me/?text=I%20found%20a%20great%20website.%20Check%20out%20this%20link%20https%3A%2F%2Fwww.example.com%2F">Share on WhatsApp</a>

• A Contact me button with prefilled text : A combination of the above two, Might be useful if you want to get a prefilled custom message from users landing on a particular page. Use format https://wa.me/whatsappphonenumber/?text=urlencodedtext

  <a href="https://wa.me/15551234567?text=I%20am%20interested%20in%20your%20services.%20How%20to%20get%20started%3F">I am interested</a>

i used this code and it works fine for me, just change +92xxxxxxxxxx to your valid whatsapp number, with country code

<script type="text/javascript">
        (function () {
            var options = {
                whatsapp: "+92xxxxxxxxxx", // WhatsApp number
                call_to_action: "Message us", // Call to action
                position: "right", // Position may be 'right' or 'left'

            };
            var proto = document.location.protocol, host = "whatshelp.io", url = proto + "//static." + host;
            var s = document.createElement('script'); s.type = 'text/javascript'; s.async = true; s.src = url + '/widget-send-button/js/init.js';
            s.onload = function () { WhWidgetSendButton.init(host, proto, options); };
            var x = document.getElementsByTagName('script')[0]; x.parentNode.insertBefore(s, x);
        })();
    </script>
