Before you start, make sure you have :ref:`installed pdfminer.six<install>`.
The second thing you need is a PDF with AcroForms (as found in PDF files with fillable forms or multiple choices). There are some examples of these in the GitHub repository under `samples/acroform`.
Only AcroForm interactive forms are supported, XFA forms are not supported.
