M-Pesa Integration for Websites: What Business Owners Should Know
Digital Marketing · Web Development · Updated 2026
How M-Pesa Website Integration Works
M-Pesa integration typically uses Safaricom’s Daraja API, which lets a website trigger STK Push payment prompts directly to a customer’s phone, or accept payments through paybill/till number confirmation, without the customer needing to leave your site.
| Integration Option | How It Works |
|---|---|
| STK Push (Lipa Na M-Pesa Online) | Customer receives a payment prompt on their phone directly from checkout |
| Paybill/Till number | Customer pays manually and the order is confirmed against the payment |
| Third-party payment gateway | A payment provider handles M-Pesa alongside card payments in one integration |
What to Consider Before Integrating
Confirm transaction fees charged by Safaricom or your payment gateway, plan for proper testing in a sandbox environment before going live, and make sure failed or pending transactions are handled gracefully so customers aren’t left confused.
Security Matters
Payment integrations should never expose API credentials in front-end code, and all payment confirmation should be verified server-side rather than trusted purely from the customer’s browser.
