How can I integrate the ETChat into my existing system using PHP?

To integrate the ETChat into your existing system using PHP, you can utilize the ETChat API to send and receive messages. You will need to authenticate your system with the ETChat API using your API key and secret. Once authenticated, you can make API calls to send and receive messages within your existing system.

<?php

// Set your API key and secret
$apiKey = 'YOUR_API_KEY';
$apiSecret = 'YOUR_API_SECRET';

// Authenticate with ETChat API
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://etchat.io/api/v1/auth');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query([
    'api_key' => $apiKey,
    'api_secret' => $apiSecret
]));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// Parse the authentication response
$authResponse = json_decode($response, true);

// Use the auth token for further API calls
$authToken = $authResponse['token'];

// Example API call to send a message
$message = 'Hello from ETChat!';
$recipient = 'USER_ID';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://etchat.io/api/v1/send-message');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query([
    'api_key' => $apiKey,
    'auth_token' => $authToken,
    'message' => $message,
    'recipient' => $recipient
]));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// Handle the API response as needed
$responseData = json_decode($response, true);

?>
