If you have shipped a serious product in Nigeria (or most of Africa), you have probably integrated both Paystack and Flutterwave. You do it for coverage, for redundancy when one provider has a bad day, and sometimes for better rates on a given card or channel.
And every single time, you rewrite the same fragile glue: two different request shapes, two different webhook signature schemes, two different ideas of what an "amount" is, two different error formats. I got tired of copying that layer between projects, so I built it once, properly, and open-sourced it.
It is called pay-kit: one typed TypeScript SDK over Paystack and Flutterwave. Swap the provider, and your code does not change.
