You have to parse the JSON encoded data which is in the HTTP request body sent out by the HTTP Alarm Callback. - [http://docs.graylog.org/en/2.3/pages/streams/alerts.html#http-alert-notification](http://docs.graylog.org/en/2.3/pages/streams/alerts.html#http-alert-notification) - [https://secure.php.net/manual/en/book.json.php](https://secure.php.net/manual/en/book.json.php) ---

Dear Jochen, Thank you for your advise. I did following your replied and I got the result “Array”. How do I retrieve the alert message? Here is my code $data = json\_decode(file\_get\_contents(‘php://input’), true); $message = $data; Best & Regards, Keetawat ---

Please consult some PHP support forum or chat for these questions. They’re not related to Graylog. ---
