I have been doing affiliate marketing for companies now it's been up to like 4 years. Affiliate is a side hustle that makes you passive income every week or month. Konga have affiliate, they pay you (affiliate marketer) 10% of the products your referral bought. Same as Jumia.
For example if your referral buy powerbank of ₦3000 they pay you ₦300 for bringing a customer that buy something. But recently I found a startup company that is into digital services like graphic and designs, website designing, content writing and their affiliate is ₦1000 per a service your referral order. So if you have 3 referrals and they buy any service in a week you'll make ₦3000 . Hmmmmm you make your data money that week. Unlike Jumia and Konga that pays you 10% as if you are a messenger from the gods to collect their tithe (lol).
Also they have customer support for affiliate marketers too, so if you have issue with withdrawing, registration etc You can chat them up on whatsapp.

The little challenge is they only use website link no banners. You might need to add little write up.
