I'm making telegram bot using webhook on php. The problem is that the webhook doesn't set correctly and idk whats the matter. my setwebhook code :
$ch = curl_init(API_URL);
try {
$cert = new \CURLFile(SSL_KEY);
apiRequest('setWebhook', array('url' => WEBHOOK_URL , 'certificate' => $cert));
echo "webhook set";
} catch (Exception $e) {
echo "error";
}
