JSon Tip Provider
A JSon Tip provider requires a JSon file with information. The TipProvider implementation can be very simple. An accompanying JSon file is dynamically fetched from the internet or it is statically included with your bundle.
In case you pull it from the internet, make sure that you do not waste bandwidth by pulling a file that you already have (use the HTTP HEAD function).
