When one of your referred users performs a sale, your commissions are shown in your Affiliate page, under My Money > Affiliate.
In the sales commission table, each sale is represented by a line, showing:
The date of the sale
Your net commission
The Status of the transaction
Here's a sample table
The status of the transaction can have 4 values, each represented by an icon:
Pending
represented by an orange hourglass, it means that your transaction has been registered and you need to wait 45 days for it to be finalized/approved.
Valid
represented by a green checkmark, it means that your transaction has been registered, it has waited the 45 days, and is available for payout.
Invalid/Rejected
represented by a red X, it means that this transaction has been rejected. Two are the main reasons for rejection: the user has requested a refund, or the transaction was fraudulent
Paid out
represented by a green banknote, it means that this transaction was valid, and it's already been paid out to you.
