M-Pesa Integration
STK push, C2B, B2C, and paybill flows wired in properly. We handle the callbacks, timeouts, and duplicate confirmations that turn a demo integration into a support burden once real volume arrives.
API & Payment Integration
A payment that fails, duplicates, or cannot be reconciled becomes a support problem. The developers at Upeo Africa Technologies integrate M-Pesa, Airtel Money, bank, and card payments, and the APIs between accounting, CRM, and inventory, for businesses in Kenya and across Africa.
How we help
Our developers have put M-Pesa, Airtel Money, bank transfer, and card payments into live products, and the failures are familiar: callback retries, timeouts, duplicate confirmations, and a reconciliation that has to survive an audit rather than only look right on screen.
The same team connects accounting, CRM, inventory, and messaging, so the same record stops being retyped between three systems by three different people.
A short call, a clear plan, and a quote before you commit.
What API & Payment Integration covers
Take the whole thing, or start with the one piece that is costing you most right now. Either way it is the same team and the same contract.
Airtel Money & Card Payments
Airtel Money alongside card and bank rails, so customers pay the way they prefer instead of abandoning the checkout. One reconciled record regardless of which rail they chose.
API Development
REST and GraphQL APIs for your own products and partners, documented, versioned, and secured. Built so the team integrating against them next year does not need to call you.
Third-Party Integrations
Accounting, CRM, inventory, SMS, and logistics platforms connected to each other. Data flows once, automatically, instead of being exported and re-keyed by somebody every Friday.
How Upeo Africa Technologies delivers API & Payment Integration
Questions, answered
The things clients ask us before they commit. If yours is not here, ask it directly and we will answer it straight.
- Can you integrate M-Pesa with our existing system?
- In most cases yes, whether it is a website, a mobile app, or an internal system. Our developers work with the Daraja API and handle registration, callback URLs, and the go-live process, which is where most in-house attempts stall.
- How do you handle failed or duplicate payments?
- With idempotent handling and a reconciliation process, because at real volume both will happen. Every transaction is recorded with its provider reference so a duplicate confirmation cannot double-credit an order and a timeout does not lose a payment.
- Is the integration secure enough for financial data?
- Credentials are held in secrets management rather than in code, all traffic is encrypted, callbacks are verified against the provider, and access is logged. We do not store card data ourselves; that stays with the payment processor.

Custom Web Applications
Spreadsheets and off-the-shelf tools stop fitting once the work outgrows them. Our developers build the web platform around the way your team actually works, so people stop keeping a second system on the side.
