Preferences

You can adapt the Checkout Pro integration to your business model by configuring preferences attributes.

Preferences attribute settings allow you to define installments, exclude an unwanted payment method, change the due date of a certain payment, in addition to obtaining business information and measuring the effectiveness of your ads on platforms such as Facebook and Google.

See below for a complete example of preference.
