Pesapal API Integration Guide for Developers (Kenya Payment Gateway)

Learn how Pesapal makes it easy for Kenyan businesses to accept M-Pesa STK Push, Visa, and Mastercard payments online — with automatic payment notifications built right in. See a live PHP demo.

If your website can't accept payments, you're losing customers every single day.

Imagine a customer visits your website, finds exactly what they want, and is ready to pay — but there's no payment option. They leave. That sale is gone. This is the reality for thousands of Kenyan businesses that still rely on manual bank transfers or WhatsApp messages to collect money.

The good news? It doesn't have to be this way. With Pesapal, your website can accept M-Pesa payments, Visa cards, and Mastercard — all from one simple integration. We've built a live working demo that shows you exactly how it works, and in this post, we'll walk you through it in plain English.


What is Pesapal?

Pesapal is one of Kenya's most trusted payment gateways, used by thousands of businesses across East Africa. Think of it as a digital cashier that sits on your website and handles all the complex work of collecting money from your customers — whether they're paying via M-Pesa on their phone or swiping a card from abroad. It supports robust security measures including SSL encryption and provides merchants with a dashboard to track transactions and generate reports.


What Our Demo Covers

We built a fully working Pesapal integration (in PHP) that demonstrates four key things your business needs:

1. Order Submission & Redirect Flow

When a customer clicks "Pay Now" on your website, Pesapal takes over seamlessly. Your website sends the order details — the customer's name, email, phone number, and amount — to Pesapal. Pesapal then presents the customer with a clean, professional payment page. Once done, they're redirected back to your website. No complicated setup on your end, no card details ever passing through your server.

2. M-Pesa STK Push (Mobile Money)

This is the feature your Kenyan customers will love most. Instead of a customer having to open their M-Pesa app, navigate to Paybill, and type in numbers manually — the STK Push sends a payment prompt directly to their phone. They simply enter their M-Pesa PIN and the payment is done. Fast, familiar, and frictionless.

3. Card Payments (Visa & Mastercard)

Not all your customers will pay via M-Pesa. Some may be using a company credit card, paying from abroad, or simply prefer their bank card. Pesapal handles Visa, Mastercard, and American Express — so you never have to turn a customer away because of how they want to pay.

4. IPN — Instant Payment Notification

This is the behind-the-scenes magic that makes everything reliable. IPN (Instant Payment Notification) is how Pesapal automatically tells your website the moment a payment is completed. Your system gets updated immediately — no manual checking, no delays, no awkward "did the payment go through?" phone calls. It's what separates a professional payment system from a makeshift one.


Why This Matters for Your Business

Every day that your website can't accept payments is a day you're sending potential customers elsewhere. With a Pesapal integration:

  • Customers can pay at any time — even at midnight, even when you're not available
  • You get notified instantly when money comes in
  • You look professional and trustworthy to first-time visitors
  • You can accept customers from anywhere — Kenya, the region, or internationally

Pesapal enables merchants across Kenya, Uganda, and Tanzania to accept card and mobile money payments both online and in-store, making it a strong choice whether your customers are local or regional.
