You (or your techie) can create programs that do much of the work for you automatically, such as starting surveys or broadcasts or having users opt-out of your list. Your website or your application can automatically perform many of the tasks that are done through our web interface.
Our API is very simple and straightforward. It is built on a simple REST model and returns either XML or JSON. Each function is defined in the menu to the left, and describes the URL and parameters for the request. We even provide a test tool for each function which helps you quickly build the REST requests and provides a response to show you what the returned objects look like.
