Dummy webhook handler for testing. Saves incoming data to a file.

webhook-handler.php

/**
 * Just place this file on the webserver and then point your webhook to the location.
 * This will save the incoming timestamp and data to a webhook-handler.log file in the same folder.
 * Use `tail -f webhook-handler.log` to monitor the log file.
