First a disclaimer: I am not the maker of Contact Form 7 or associated with it’s author.
That being said, I think Contact Form 7 is great…except for one thing. It does not save or post its information. 
This plugin allows to save history of submits and send XML REST call to web service. 
It can easily be modified to make other than XML data calls.
