Adding a Paypal payment field to your form is easy. Just open the Payment Tools while on the form builder and drag either, Paypal (Standard), Paypal Pro or Paypal Express to your form.
After that, the payment wizard should appear. Simply enter your Paypal credentials e.g. Paypal Email for Paypal Standard, proceed to the next page and create your products. Complete the setup and that's it.
