The application allows users to create a custom endpoint, with a custom JSON payload, which will be POSTed whenever YOTTP is yo'ed. This application is for the Yo power user who may have a home automation setup or two. Alternatively, a user of Twilio can also use the application to make routine calls/send usual SMSs with the tap of a button.
The user interface is intentionally sparse, in order to maximize usability from all platforms, and to minimize support requests from users who aren't sure of what they're doing.
The best part about this application is the way it queues requests. This application can handle more than the free-limit of 30 requests/second imposed by Parse, as it implements queueing of the requests sent from the Parse server.
