The coupon code attribution model is a 30 day fallback, the same as our click-through conversion. This is also the standard for Google Analytics. If a customer clicks the ad served by the platform with the coupon applied at the click, this will be counted as only a click-through conversion and the coupon will display in the orderID report for display purposes only. The platform will only attribute a coupon code to a sale if a customer finds a custom (to SourceKnowledge) coupon code and enters it manually.
