How to Integrate M-Pesa Seamlessly in Your E-commerce Store

Integrating M-Pesa is a must for any Kenyan e-commerce business. In this post, I break down the process I used for Apple Junction Kenya, including:

1. Setting up the Safaricom Daraja API
2. Handling payment callbacks securely
3. UX tips for mobile-first checkout
4. Testing with the M-Pesa sandbox

Code Example

const response = await fetch("/api/mpesa", { method: "POST", body: JSON.stringify(order) })

Lessons Learned

• Always validate payment status server-side
• Show clear feedback to users on mobile
• Handle network failures gracefully
