Adding a discount code actually speaks for itself. When setting up a payment button for a certain product, you will give the option to add a discount code.
Once you've added it, you can choose whether it's an absolute or a relative discount. You can also manage until when the discount code is valid and how often the discount code can be used.
The best way to add or manage a discount code is to do the following steps:
Go to the PayPro website
Log in to your account
Go to 'Manage payment buttons' in the left menu
Select your product by clicking on its name
Scroll down to 'Discount codes'.
