WhatsApp limits the content of text messages with which you can start a conversation with a customer or continue a conversation 24 hours after the customer's last message. This message must be a pre-approved template. There is a charge for sending the template, as it initiates the conversation. If the client responds to you, you can communicate with them for free for 24 hours from the time you receive the response. Read more.

Receive notifications about personal messages through incoming http requests to your server. This is the main function for creating a chatbot. All you have to do is change the token and the instance number.
// First of all - set a webhook to URL like http://your_website.com/my_webhook_url.php
// Parse a webhook data
$data = json_decode(file_get_contents('php://input'), true);
foreach($data['messages'] as $message){ // Echo every message
// Handle every message here
// Add to the database or generate a response
}
// First of all - set a webhook to URL like http://your_website.com/my_webhook_url
// Require Express JS и Body Parser for JSON POST acceptance
var app = require('express')();
var bodyParser = require('body-parser');
app.use(bodyParser.json());
// Handle POST request
app.post('/my_webhook_url', function (req, res) {
var data = req.body; // New messages in the "body" variable
for (var i = 0; i < data.messages.length; i++) { // For each message
var message = data.messages[i];
console.log(message.author + ': ' + message.body); //Send it to console
}
res.send('Ok'); //Response does not matter
});
app.listen(80);
You can view and edit your Whatsapp profile. However, if you want to change your display name, there are a few rules.
$data = [
'address' => '79995253422', // Recipient's phone
'description' => 'Best Company', // Message
'email' => '', // Email of the organization
'vertical' => '' // The industry
];
$json = json_encode($data); // Let's encode the data in JSON
// URL for POST request /message
$token = '8376213g87x';
$instanceId = '777';
$url = 'https://api.chat-api.com/instance'.$instanceId.'/me?token='.$token;
// Let's form the context of an ordinary POST request
$options = stream_context_create(['http' => [
'method' => 'POST',
'header' => 'Content-type: application/json',
'content' => $json
]
]);
// Let's send a request
$result = file_get_contents($url, false, $options);
