You can give a specific affiliate their own payout on an offer. You add an affiliate specific payout to the offer and fill in the amount for the conversion types you need, such as Sale or Lead.
First, go to Offers → Offer list, open your offer, and navigate to the Revenue & payouts section.
Then click Add affiliate specific payout.
You can then choose which affiliate you would like to receive a specific payout.
Fill in the payout for the relevant conversion type (Sale, Lead, or another type depending on your offer).
If you'd like to add another affiliate, click Add affiliate specific payout again.
When you're done, scroll to the bottom of the page and click Save.
