Referral Window Explained

The referral (or cookie) window starts after a partner-driven click or event. If the customer purchases within that window, impact.com credits the partner. Understanding this timing helps you predict attribution and resolve disputes.
Contract-level setting — Each contract between you and a partner defines its own referral window.
Action-date logic — The referral window that applies will be determined by the contract that was live when the corresponding tracked action took place (Action Date).
Referral window follows the active contract — Whichever contract was in effect on the action date governs the referral window for that action, even if the contract has since been updated or replaced.
When you update a contract's referral window or move a partner to a new contract, the change applies to actions that occur on or after the new contract's start date. Actions that occurred under the previous contract retain the window that was in place at that time.
May 20
Current contract (May 15–31)
15 days
June 4
June 5
Upcoming contract (June 1 onwards)
1 day
June 6
In this example, a customer who clicked a partner link on May 20 has a 15-day window, so impact.com credits the partner for conversions through June 4. A customer who clicked on June 5 has a 1-day window, so impact.com credits the partner only through June 6.
Predictable attribution — Because the window is locked to the action date, both you and your partners can calculate exactly when a conversion will or won't be credited, regardless of later contract changes.
Fair partner compensation — Partners are compensated based on the terms they agreed to at the time they drove the traffic, not on retroactive contract updates.
Troubleshooting missing conversions — If a conversion isn't attributed as expected, check whether the click occurred under a contract with a shorter window than the current one.
