Integrating with HTTP Servers (including handling attachments)
Live Forms can POST form or workflow data to your web server for processing. There are two options available [[V4_Designing_Forms#Post_Data_then_Forward_to_Web_Page | Form Action POST]] and [[V4_Designing_Forms#Post_Data | Doc Action POST]]. The difference between the two is that the Form Action POST displays the response from the web server to the user whereas the Doc Action POST does not.
Processing form data POSTed to your web server is [[Process_Submissions_Tutorial#POST_to_your_web_server | detailed in this Tutorial]].
