Coupon Code Used

When a customer applies a coupon code assigned to a collaborator during checkout, the “Coupon Code Used” event is triggered. This creates an engagement linking the purchase to the collaborator who owns that code.

Coupon A customer applies a collaborator's coupon at checkout

Engagement Siren creates an engagement tying the sale to the collaborator

Points The engagement gets points from the program's settings

Why this trigger usually wins

Coupons get applied at the very end of the buying process, which means the Coupon Code Used event typically fires after every other engagement for the same customer. When a program uses a “newest engagement wins” sorter, the coupon owner usually gets the conversion. That makes this trigger the anchor for most coupon-based influencer programs, where the collaborator’s entire contribution is tied to whether their code gets used.

Which integrations support it

WooCommerce, Easy Digital Downloads, and NorthCommerce all detect the coupon the moment it’s applied at checkout. LifterLMS works a little differently because it doesn’t expose a hook for coupon application. Siren detects the coupon at the time the sale completes instead, so the engagement is created alongside the conversion rather than before it. Either way, the collaborator gets credit.
