How can I delete Payment Tools?

You can remove them in the same manner as you would remove any other widget or field on your jotform, by clicking on the little x in the quick actions toolbar

Once you do you will be asked if you want to save the products or remove them completely.

If you select Yes when you add another payment processor to your jotform it will automatically pick up the products that you had added before, while if you click on No, it will completely remove the tool and the products added to it.

If you want to add another payment tool, I would recommend Yes, but if you are having some issues then No might be a better way to go - of course we are here in that case as well if needed :)
