When I get a Notification email when some one signs up for my service will it fill in all of the fields itself or will the customer have to fill it.Asked by chadwickseafood on July 28, 2016 at 05:24 PM
As you're asking only for the email address in your form, this is the only field filled that you will receive on your email notification.
If you have some custom fields on the PayPal side, then your customers will need to fill them as it is not possible to pass custom data from the form to PayPal.
However, you may provide us more details about your question, we will be glad to further assist you.
