Does any PayPal options allow for limiting the number of products sold?

hi,

do any PayPal options allow for limiting the number of products sold?

thanks

It would not be possible to do that with the PayPal payment integration, but you could use a widget instead, for example, the Inventory widget could help you limit the options: https://widgets.jotform.com/widget/inventory  

Then you will need to perform the calculations and pass the result to the payment field. The guides below will assist you.

I hope this helps.
