A tracking cookie is set when visitors click the link.
Customer purchases via Paddle checkout
The referral code is passed as passthrough data or custom data in the Paddle checkout.
Paddle sends webhook to Refgrow
transaction.completed notification arrives with the passthrough referral data.
Commission attributed automatically
Refgrow matches the referral code to the affiliate and records the commission.
