Adds the Discount source property and removes the Discount coupon propertyBreaking changes

What’s new

This change adds a new source property to the Discount object and removes the auto-expanded coupon property. The new source property is a hash that contains the following attributes:

• type: The type of object used to calculate and apply the discount.
• coupon: The Coupon redeemed to create the discount.

Why is this a breaking change?

This is a breaking change because:

• The Discount object’s schema is changing, which requires you to handle responses containing Discounts differently.
• The Coupon object is not automatically expanded on Discount objects, including within event notifications.

Impact

The coupon property no longer auto-expands on the Discount object. To retrieve details about a discount’s coupon, either retrieve it separately or expand it through the source property.

This change has no impact on how coupons are redeemed into discounts today, but enables expanded discounting functionality in the future.
