Integration with API for Platypus

I have suiteCRM up and running, and what I want to be able to do is to export a contact from suiteCRM into our existing billing software. The billing software has an API for this purpose, so all I would need to do is output certain fields from the suiteCRM contact into an specifically-formatted XML file and transmit that to the server. Is there a simple way to do this, say by building a connector, or do I have to build an entire module all the way down to the bean level?
