Timing depends on the merchant and affiliate network. The qualifying event must be tracked, reported, and confirmed before it becomes eligible for payout.
Unlisted coupon codes, other reward extensions, an existing or ineligible customer account, excluded products or plans, and leaving the tracked session can prevent a reward from being credited. The merchant terms control eligibility.
