HTTP Request - Completed Event

Fired when the HTTP request returns after processing successfully

The Completed event is fired when the request completes successfully.

Event routines are best coded within the method that the requested is executed in.

In this example, a weather API is executed asynchronously, returning the data as a JSON object.

When the completed event fires, the result is processed.
