Open the form you want to add a PayPal payment gateway to and click Settings.
Click Payment Options and select PayPal, if it isn’t already selected.
Set the currency and tax percentage, and write in your PayPal email.
If you want to test out the payment gateway first, keep the “Checkout Mode” on Testmode and if you are ready to go live, select Production.
Now when you add any payment-receiving forms, such as “Price,” your users will send those payments via PayPal.
