Reaction has support for discount codes and discount rates. A "code" is a code that can be applied during checkout that applies a discount to the cart subtotal. A "rate" is a discount that is applied without needing a discount code to be applied.
Discount codes can be enabled in the Payments settings in the Reaction dashboard.
Discount Code, case-sensitive string for a code
Discount, a discount formula value (string or number)
Account Limit, per user limit for this code
Total Limit, per code usage limit
- credit - a credit is applied to the order subtotal up to the formula value
- discount - the formula value applied as a percentage discount off order subtotal
- sale - overrides item pricing with a fixed sale price
- shipping - the formula value should be a string that matches the name of a shipping method. The calculated shipping rate will be applied as a discount.
Discounts are validated when a user enters a code during checkout, and are applied as payment methods on the cart. The discount code usage is tracked once the order has been placed.
