We want to use Formidable Pro 2 PDF to populate some fields on a custom certificate we have designed. It is not clear whether Formidable Pro 2 PDF only works with the template you offer, or if we can make our own. Can you clarify this?
PRO2PDF is designed to fill PDF forms with Formidable Form data. You upload your own PDF form (with adobe form fields) to PRO2PDF, then design your own template using the Field Map Layout Designer to map the web form fields to the PDF form fields.
The free version is in the WordPress Plugin Repository, you can also try the free version of our newest plugin E2Pdf which works with Formidable as well as many other form plugins like Gravity, Forminator, Divi Contact Form, Caldera, with more being added all the time.
