Make a Square payment form require a payment, not a product.

Can I have a Square payment form on my website that does not require the customer to buy a product, but just make a payment?

Thank you for contacting us. That would be possible, you just need to change the payment type to "User Defined Amount":

If the amount to be paid will be calculated, you can do it through a Form Calculation widget: https://www.jotform.com/help/259-How-to-Perform-Form-Calculation-Using-a-Widget

Then, you can pass that amount to your payment field: https://www.jotform.com/help/275-How-to-Pass-a-Calculation-to-a-Payment-Field

Let us know if you need more help, we will be glad to assist you.
