通过Jquery的HTTP命令

I've been asked how we can send and receive HTTP requests to trigger a Mobile Text billing service. The billing service has no webservice to respond/trigger these message and will only take requests from a whitelisted IP. Therefore I assume we need a server side web service written that can handle a client request - trigger a billing message and return a reply to the client jquery/ajax.

This is coming from a fron-end developer with limited back end knowledge though! Therefore does anyone agree with my assumption - before I respond!?

A webService is most prefferable. it gives more flexibility for future changes on the front end architechture (or type)
