title: Trigger Amazon SNS message via Amazon Lambda
body: <p>I have an Amazon Lambda instance and an Amazon SNS instance. The Lambda code watches for changes in our database and I would like it to make a call to Amazon SNS to send pushes to our users. For example:</p>
  
  <p>When a user on one of our forums gets a new message, the Lambda code recognizes this change every time it is run (every 10 minutes) and should send a push to the user's smartphone via SNS. </p>
  
  <p>I'm running into a wall when it comes to the documentation; Amazon's docs only talk about how to trigger Lambda code via SNS, but not the reverse. Does anyone have an example of how I can accomplish this?</p>
