Introduction

The eCommerce Custom Discount Triggers service plugin (formerly SPI) allows you to provide custom triggers that specify when an item can be discounted.

Custom triggers play a part in the definition of discount rules - sets of triggers and scopes that together define the necessary conditions for a discount to apply to items in the cart/checkout.

Before you begin

To use a custom trigger:

• Provide your custom triggers by implementing the listTriggers() function.
• Implement the getEligibleTriggers() and provide the logic needed for applying the relevant custom triggers.
• Create an automatic discount using the dashboard, or by using the Discount Rules API.
