   This would be an excellent feature of the API Gateway 👏. Websocket support is something developers ask about a lot... 
   
   - We would need to define the error handling process when the the triggers are unavailable or rate-limited. How would we signify to a client that a message wasn't delivered?
   
   Another (more difficult) thing to consider is how to make it possible for messages to be sent to listening clients outside of responding to an incoming event. If we take one of the most common examples for a websocket application, a chat application, how could we enable this feature? 
   
   Ideally, an action could call the API Gateway service with a message to pass to one or more clients currently connected to pass messages that arrived from other sources.
