Each new purchase will have
Pending status. It means that current order is assigned to user. Then, merchant can approve this order or decline it (
Approved status and
Declined status). Make sure that you understand that merchant can take few weeks before he approve order. It means that you will not have commission and can't pay it before order will get approved status. Usually, we recommend to notice users that they will get cashback in 3-4 weeks after purchase.
