Take a look at this video on how to create a web forms that can send data to Dataflow Automation.

An example HTML File can be found here to get started. https://www.dropbox.com/s/ggbi73qsm9ds4b0/web_form_example.html?dl=0

A couple examples I can think of for this usecase are below

• Web form service request is filled out, it creates a record in iFormBuilder or DC and is assigned out to the users mobile devices for completion.
• Upon submission of the Web Form an email is sent out the customer through Dataflow Automation and the record is stored within Zerion Reports for analysis

Please feel free to share more examples on to this post.
