Payments confirmed automatically
No more checking phone messages to see who has paid. Your system knows instantly.
Connect your businessto M-Pesa andevery tool you use
We build secure API integrations that link your website, app or software to payments, SMS, tax, accounting and delivery services, so orders and money move without anyone copying data by hand.
We connect your business to M-Pesa
What is API integration?
An API is a way for two systems to talk to each other. When a customer pays with M-Pesa on your website, your site sends a request, M-Pesa sends the prompt, and a moment later M-Pesa tells your site the payment is done.
API integration is building and testing those connections so they run on their own, every time, without staff copying numbers between screens.
Done well, nobody notices it. Orders update, receipts go out and your records match, even at 2 a.m.
No double entry
Sales, invoices and stock update once and flow to every tool that needs them.
Faster for customers
Prompts, receipts and delivery updates arrive in seconds, which builds trust.
API integrations we build
From a single M-Pesa button to a full set of connected systems. Pick one or combine several.
M-Pesa (Daraja) integration
Take payments and send money with STK Push, paybill and till payments, and have every result confirmed back to your system automatically.

SMS and WhatsApp messages
Order updates, payment receipts, reminders and one-time codes sent automatically at the right moment.
Order updatesRemindersOTP codesBulk SMS

What happens behind one payment
Hover the stack or pick a layer. Every integration follows the same safe path, so nothing is lost on the way.
- 1. Your app asksA customer taps pay and your system sends a clear, validated request.
- 2. Secure gatewayKeys stay on the server, traffic is encrypted and every call is logged.
- 3. The provider answersM-Pesa, the bank or the SMS service processes the request and replies.
- 4. Callback closes the loopWe verify the callback, update the order and tell the customer.

Built so no payment goes missing
Connections fail sometimes: networks drop and providers have bad days. We design for that, so you do not lose orders or money when it happens.
- Keys kept safe on the server
- Retries when a service is slow
- Callbacks verified before we trust them
- Every request logged
- Alerts when something fails
- Full sandbox testing before go-live
Signs you need an API integration
Ask for a free review- Staff copy M-Pesa payments into a spreadsheet by hand
- Customers pay but the order stays pending
- You type the same invoice twice, once for sales and once for tax
- Stock in your shop and your records never match
- Order updates and reminders are sent manually
- Two tools you rely on cannot share data
How we integrate
You see each connection working before it touches real money or real customers.

Connect
We set up sandbox access and build the connection with secure keys and clear error handling.

Questions about API integration
Cannot find your answer? Send us a message and we will reply.
What is API integration?
An API lets two systems talk to each other. API integration is building and testing that connection, for example so your website can ask M-Pesa for a payment and be told automatically when the customer has paid.
Can you integrate M-Pesa into my website or app?
Yes. We integrate M-Pesa Daraja for STK Push, paybill and till payments, payouts and transaction status checks, with callbacks that update your orders automatically. We also guide you through the go-live steps with Safaricom.
How much does API integration cost in Kenya?
It depends on how many services you need to connect, how complex the rules are, and whether the provider needs an approval process. Tell us what you want to connect and we will send a quote.
How long does an integration take?
A single, well-documented integration such as an M-Pesa STK Push can take a few days to a couple of weeks. Several systems, custom rules or provider approvals take longer. We give you a timeline once we know the scope.
Can you connect to my existing system?
Usually yes. If your software has an API, a database or can export data, we can connect to it. If it has none, we can build a small bridge so it can share data with other tools.
Is it secure?
Yes. API keys are kept on the server and never in the browser, traffic uses HTTPS, callbacks are verified before we trust them, and every request is logged so you can trace what happened.
What happens if a service goes down?
We build retries and queues so a slow or unavailable service does not lose your data. When something keeps failing, you get an alert and a clear message is shown to the customer.
Do you support the integration after launch?
Yes. Providers change their APIs from time to time, so we monitor, fix and update integrations under a support plan, and your team can reach us any time.
