How can I create a succesful form to generate certificates.

How can I create a form to generate certificate template

Are you trying to create a form where it will generate a certificate? We do not have such a feature, but let me try to figure out a workaround. I will update you via this thread.

Hi again, an option would be setting up the image of the certificate as the background for the PDF: https://www.jotform.com/help/384-How-to-Customize-PDF-Submissions-Report 

Then you can attach that PDF in the Autoresponder that is sent to the user: https://www.jotform.com/help/503-How-to-include-submissions-as-PDF-attachment-in-the-email-notifications 

Also, you may try any of the PDF certificate templates we have. If you have your own certificate, you can set it as the background of your PDF document as explained before.
