Adding promo code to square appointments

[Shellebrate33]

When a customer is trying to book a tour online, it says "add promo code", how do I set up the promo code? It's different then "discounts". I already know how to work the discount option. Thanks!

Hello there @Shellebrate33 

Would you mind sharing a link to your Booking site and a screenshot of where you're seeing the "Add Promo Code" option? With this I will be able to point you in the right direction.
