Back in March, SimpleMDM (of which I am a big fan) announced they were adding webhooks to their Mobile Device Manager. These allow you to send an HTTP POST to the URL(s) of your choosing when certain events occur in your SimpleMDM account. Following this announcement, I built an AWS Lambda function for responding to these events, partly as a learning. This function is designed to allow for more sophisticated response whenever a device is enrolled or unenrolled in SimpleMDM.
