I am creating a registration form for a Charity Golf Tournament. Once users register, they will receive an email thanking them for signing up and an invoice generated through Gravity PDF. Following registration and receipt of the automated invoice.
After the users receive the invoice via their email, there should be a link that prompts them to upload proof of payment directly or a form linked with the registration form. Does anyone have suggestions on how to accomplish this without users having to send an email with the payment proof attached?
