When a user clicks on an affiliate link, a unique number is generated. The number is called Click Id and is used as an identification method for keeping a track of potential customers. This way, if a purchase is made, the merchant will know which affiliate partner has made it possible. Postback pixels accompany the Click IDs, ensuring that the ClickSure servers are notified each time a customer has made a purchase via the affiliate link. This way, the ClickSure system will have all the right information, which is needed to credit the right affiliate partner with the right commission.
