M-Pesa Daraja APIs: Complete Developer Integration Guide

Master every aspect of Safaricom's Daraja API platform with this comprehensive guide to M-Pesa integration. From STK Push and payment processing to B2C disbursements, transaction queries, and account balance checks—this series covers the complete Daraja ecosystem.

Daraja isn't just one API; it's an entire platform of products that let you collect payments, send money, check balances, handle recurring subscriptions, and more. Each API has its own quirks, requirements, and use cases. This collection breaks down every major Daraja product with the depth you need to implement it correctly.

We start with the fundamentals that apply across all Daraja APIs—authentication, credentials management, sandbox vs production environments—then dive deep into each specific API. You'll learn the concepts first so you understand the why behind every step, then see exactly how to implement them in production-ready code.

This isn't regurgitated documentation. These articles come from years of building real systems with Daraja, teaching hundreds of developers, and solving the exact problems that official docs leave unanswered. You'll learn not just what to do, but why it matters, how to handle edge cases, and what to watch out for in production.
