I have a website [login to view URL] where I sell Certificates and other items. I already have a system set up that people can input their pet data and it will generate a PDF certificate that gets emailed to them. I have that set up within Shopify and a separate server delivers the PDF. I have codes from Groupon that will offer 1 or 2 of these certificates for free. Groupon will not work on Shopify so I need this moved to my other server and deliver the same product. Please do not say you can do it without actually looking at the project first. Thank you.
