In Kenya, M-Pesa has completely transformed the way people pay for goods and services. With millions of users relying on it for daily transactions, integrating M-Pesa into your e-commerce website is no longer a luxury — it's a necessity.
Why M-Pesa Integration Matters for Your Online Business
Widespread Use in Kenya
M-Pesa dominates Kenya's digital payment landscape, with over 30 million active users. When you integrate M-Pesa, you instantly make your online store more accessible and trusted by Kenyan shoppers.
Faster and Safer Transactions
Unlike traditional bank transfers, M-Pesa payments are instant and secure. Customers can make payments using their mobile phones in seconds, reducing abandoned carts and increasing your conversion rate.
Builds Customer Trust
Kenyans associate M-Pesa with reliability. When customers see the "Pay with M-Pesa" option on your website, they're more likely to complete their orders. It gives them confidence that your business is genuine and locally aligned.
How M-Pesa Online Payments Work
Before jumping into integration, it's good to understand how M-Pesa works in an e-commerce setting. Here's a quick overview:
The M-Pesa Payment Process:
That's the entire process — fast, secure, and easy to automate.
Step-by-Step Guide to M-Pesa Integration
1. Create a Safaricom Developer Account
Start by visiting Safaricom's Developer Portal. Create an account to access M-Pesa APIs. Once logged in, you can create a new app to generate your Consumer Key and Consumer Secret — which are required for all API requests.
What You'll Get:
- Consumer Key: Unique identifier for your application
- Consumer Secret: Secure key for authentication
- Access to Sandbox: Testing environment for development
2. Choose the Right M-Pesa API
Safaricom offers several APIs for different business needs:
Lipa na M-Pesa Online (STK Push)
Best for e-commerce sites. Prompts users to pay directly from their phones. This is the recommended option for most online stores.
C2B (Customer to Business)
Ideal for receiving payments from customers via Paybill or Till Number. Good for businesses with existing M-Pesa infrastructure.
B2C (Business to Customer)
Used when you need to send payments back to customers (refunds, payouts). Not typically used for e-commerce payments.
For most e-commerce stores, Lipa na M-Pesa Online API is the best choice.
3. Get a Paybill or Till Number
You'll need either:
Paybill Number
For businesses receiving payments linked to an account. Customers enter your Paybill number, then account number (usually order ID).
Till Number
For retail businesses, often called "Buy Goods". Customers just enter the Till number to pay.
You can apply for one through Safaricom Business. If you're a small startup, Safaricom offers Pochi la Biashara as an alternative, though it has limited integration options.
4. Set Up Your API Credentials
Once your Paybill or Till is active, Safaricom will link it to your developer app. You'll then use:
Essential Credentials:
- Short Code: Your Paybill or Till number
- Consumer Key & Secret: From your developer app
- Passkey: Provided by Safaricom for your Paybill
Store these credentials securely — you'll need them for your integration code.
5. Connect the API to Your Website
You can integrate the M-Pesa API manually or use ready plugins depending on your platform.
For WordPress (WooCommerce)
Use plugins like M-Pesa for WooCommerce by PesaPress or WooCommerce M-Pesa Payment Gateway by KenyaPay. Simply install the plugin, enter your credentials, and activate M-Pesa as a payment method.
For PHP Websites
You can implement the STK Push API using PHP cURL requests. Here's a basic workflow:
// Initiate STK push using /mpesa/stkpush/v1/processrequest
// Handle callback responses to confirm payment success
If you're not familiar with code, Angazalabs can handle this setup for you professionally and securely.
For Shopify or Custom Stores
Use third-party services like:
- PesaPal
- iPay Africa
- Flutterwave
- DPO Group
These act as payment aggregators that already include M-Pesa integration options for multiple e-commerce platforms.
6. Test in the Sandbox
Before going live, Safaricom provides a Sandbox Environment — a testing space where you can simulate M-Pesa payments without real money.
Testing Checklist:
- Test your checkout flow end-to-end
- Confirm callback URLs work correctly
- Ensure order statuses update automatically
- Verify payment confirmation emails are sent
This prevents costly mistakes and ensures smooth customer experiences.
7. Go Live
Once testing is successful, request Safaricom to move your app from Sandbox to Production mode.
After approval, you can start accepting live payments from customers on your e-commerce site.
Post-Launch Monitoring:
- Monitor payment success rates
- Set up error logging and alerts
- Track customer feedback on payment experience
- Regularly update your integration as APIs evolve
Common M-Pesa Integration Issues (and How to Fix Them)
Invalid Credentials
Double-check your Consumer Key, Secret, and Passkey. Ensure they're correctly entered without extra spaces.
Callback URL Not Working
Ensure your website uses HTTPS (not HTTP). Safaricom requires secure connections for callbacks.
Payment Delays
Might be caused by incorrect time synchronization or slow API response — check your server logs.
STK Push Not Triggering
Confirm your Paybill/Till number supports Lipa na M-Pesa Online and is properly configured.
