Catalogue Paystack & Flutterwave Payment Kit
Paystack & Flutterwave Payment Kit
One interface for both providers, with money handled exactly. TypeScript, no dependencies.
Paystack takes amounts in kobo. Flutterwave takes them in naira. Sending the wrong one is a silent hundred-fold error, and it is the most common bug in Nigerian payment integrations. This kit makes it structurally impossible: every amount is an integer count of minor units, and each provider converts at its own boundary.
It also handles the parts that only break in production — one reference per payment attempt rather than per order, webhook signatures verified against the raw body, and a check that refuses to fulfil an order when the amount, currency, reference or status disagrees with your own records.
Zero runtime dependencies. It runs on the cheapest VPS you can rent.
What you get
- Full TypeScript source, commented throughout
