How do I add Predefined Property to Stripe Payment Wizard?

I want my Payment Wizard to be my form, the product I'm making is custom for each order.  I want the customer to upload images, etc before payment.

Is this possible?

Hello foryourbridesmaid,

I am not sure if I have understood your requirement correctly.

The image you have added above seems to allow you adding predefined property. Is there anything else you want to do? Please explain your question a bit more in details and we will surely try to help you.

Please be noted that you can add condition for your payment question and if a particular product is selected, you can show / hide any form field. Please take a look at the following form where selecting "New Product 1" is selected, it will display an upload field:  http://form.jotformpro.com/form/41248746883971?

Please explain your question a bit more in detail and we will try to find any possible solution.

Thank you!

Decided to use the form with Stripe, thank you so much!
