How do I remove all payment gateways?

I have tried deleting the fields associated with the gateway. Then I recreated the form from scratch - still the paypal gateway is assigned but does not work as I haven't authenticated. I wish to remove all gateways.

You have to delete the following field in your form. Note that the products are automatically saved and they are automatically recreated when you add another payment gateway or the same one.

 

If you wish to change the Paypal email, you can open the payment settings.

Thankyou - I did try deleting that field. But I would like to list the
products with no payment gateway attached. How do I remove the
relationship? Even by creating a new form Jotform (cleverly) remembered the
gateway :(

I think what you are looking for is a Purchase order field. 

Just delete your Paypal field and get this one and the products in it should still be intact and without any payment gateway setting requirement.

If you have additional questions, please let us know.

Yes! Thankyou :) fixed
