The Brief
Paystack is one of Africa’s leading payment infrastructure companies — powering online and offline payments for tens of thousands of businesses across the continent. Their developer platform is the backbone of that infrastructure, and their documentation is the primary onboarding surface for the engineering teams building on it.
The audience for Paystack’s developer documentation is broad: solo developers building their first e-commerce integration, engineering teams at enterprise companies migrating from other payment providers, and fintech startups building complex payment flows involving subscriptions, splits, transfers, and bulk payouts.
What I Built
Technical writing work across Paystack’s developer documentation covering:
- Integration guides — Walkthroughs for core payment flows: accept payments, verify transactions, handle webhooks, manage refunds
- Payment method documentation — Platform-specific guides covering card payments, bank transfers, USSD, mobile money, and QR codes — each with its own flow, test credentials, and edge cases
- Webhook reference — Detailed documentation of every event type Paystack fires, with example payloads and guidance on idempotent webhook handling
- Code samples — Working examples in JavaScript, Python, and PHP for the most common integration patterns
Approach
Payments documentation is high-stakes. A misunderstood concept — a developer who doesn’t understand the difference between a charge and a payment, or who misses the webhook verification step — can result in failed transactions or, worse, a security vulnerability.
The writing required deep engagement with the platform: understanding transaction state machines, testing payment flows end-to-end in the sandbox environment, and handling the specific edge cases (network failures, bank timeouts, card scheme variations) that developers will encounter in production.
Every integration guide was written from a working integration — not from the API spec alone.
Results
Technical writing contributions to the documentation of one of Africa’s most developer-trusted payment platforms, helping thousands of developers integrate payments into their products with confidence.
