What are some potential pitfalls or challenges when trying to send messages to ICQ using PHP?

One potential challenge when sending messages to ICQ using PHP is ensuring that the correct API endpoints and authentication methods are used. It is important to carefully read the ICQ API documentation and follow their guidelines to avoid any errors in sending messages.

// Example code snippet using cURL to send a message to ICQ
$token = "YOUR_ICQ_API_TOKEN";
$url = "https://api.icq.net/bot/v1/messages/sendText";
$data = array(
    'chatId' => 'CHAT_ID',
    'text' => 'Hello, this is a test message from PHP!'
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Authorization: Bearer ' . $token
));

$result = curl_exec($ch);
curl_close($ch);

echo $result;
