This is a library module. It provides no out of the box functionality other then providing an API that other modules can use.
The Webclient API is seperated into three major components:
Webclient
Webclient Formatters
Webclient Proxy
All of the above components were translated to seperate modules so that developers can create a dependency with the functionality they need.
Webclient
Creates an API wrapper around cURL using an OO-based approach thus providing a more intuitive way of managing and retrieving request and response data.
This module assumes you have one or more things and you want to gate access to those things behind forms that create a RedHen Contacts. Beyond that, it also lets you track conversions (form submissions) on a thing-by-thing and contact-by-contact basis. It also lets you define your own segments for further analysis.
