API Creation using JSON and XML

we're using a software which has an API designed in JSON. We need it to communicat with our billing system wihch also uses JSON and XML.

We need ADVANCED knowledge on this as there are issues needing troubleshooting. There is no support, so we need to determine and fix the problem ourselves.

There is a WHMCS integration, but you dont need to be familiar with it right now, as long as you get the billing system and the voip to system to communicate via the API.

You will need to show the expertise you have with JSON to get a successful bid.
