API integration for
the systems you rely on.
Connect payment services, statutory portals, ERPs, SMS providers, and internal applications through APIs that are documented, observable, and designed around the data that must move.
API integration for
connected systems
Connecting a third-party service is part of a wider workflow. Our API integration services cover payment gateways such as M-Pesa and Stripe, logistics platforms, SMS providers, business systems, and the applications that rely on them.
We define an integration layer with clear contracts, retries where safe, useful logs, callbacks, and reconciliation. That gives the team a way to understand what happened when an external provider is slow or unavailable.
Connect M-Pesa, cards, banks, or other providers around the payment journey your product needs.
Receive provider updates, record state changes, and notify the right parts of your application.
A dependable API layer
A useful API gives each system a clear contract. It should make valid requests easy to understand, make failures visible, and avoid exposing data or actions that the caller does not need.
We provide backend API development in Kenya for mobile apps, web frontends, and services such as M-Pesa. The design may include idempotency, rate limits, authentication, queues, and reconciliation depending on the workflow.

Business system
integration
Organisations often need to connect older systems with newer applications. We assess what is already in place and add the smallest useful integration layer before recommending a larger replacement.
This can include connecting Oracle or SAP systems to web dashboards, synchronising an on-premise database with a hosted application, or moving records between services with clear ownership and error handling.
We review authentication, permissions, transport, secrets, logging, and data retention as part of the integration design. The controls depend on the systems and information involved.
Integration Workflow
Map users, records, interfaces, dependencies, and the outcome the integration must support.
Agree requests, responses, callbacks, error states, retries, and ownership.
Test normal and failure paths, then document release, support, and reconciliation steps.
APIs for the work at hand
The right endpoint depends on the workflow. We help teams connect the services they use and keep the request, response, callback, and support details understandable.
SMS API
Messaging integrations for alerts, one-time passwords, reminders, and other customer or internal notifications.
Connect to SMS APIAirtime API
Connect airtime distribution to the carriers and use case the product supports. Suitable for rewards, staff incentives, and other approved payment workflows.
Connect to Airtime APIM-Pesa Core
The crown jewel of our Hub. Native M-Pesa integration support for C2B, B2C, and B2B Orchestration. Handle STK Pushes, reversals, and balance queries.
Connect to M-Pesa CoreDocumentation for the team
Good developer experience starts with clear documentation, examples, useful errors, and an agreed way to test integrations before release.
- ✓ Working examples where useful
- ✓ Test requests and responses
- ✓ Error and support notes
curl -X POST https://provider.example/v1/payment-request \ -H "Authorization: Bearer {ACCESS_TOKEN}" \ -H "Content-Type: application/json" \ -d '{ "phone": "+254700000000", "amount": 1000, "reference": "ORDER_123" }'
const response = await fetch(process.env.PROVIDER_URL, { method: 'POST', headers: { Authorization: `Bearer ${process.env.ACCESS_TOKEN}` }, body: JSON.stringify({ phone: '+254700000000', amount: 1000, reference: 'ORDER_123' }) });
use Illuminate\Support\Facades\Http; $response = Http::withToken($accessToken)->post($providerUrl, [ 'phone' => '+254700000000', 'amount' => 1000, 'reference' => 'ORDER_123' ]);
Security in the integration
Access, data handling, and failure paths are considered as part of the API design.
Transport security
Secure connections selected for the environment
Authentication
Access designed around the clients and systems involved
Permissions and limits
Only the required systems and actions are exposed
Recovery planning
Backups, retries, and reconciliation where appropriate
Clarify the system boundaries before connecting them.
We define contracts, error handling, callbacks, retries, observability, and support ownership before integrations go live.
System owners, business events, data responsibilities, and the contract each side must meet.
Failure handling, retries, monitoring, change management, and support ownership.
The technical and operational teams who rely on the information moving correctly.
Documentation, operational checks, and a clear escalation path.
A useful first conversation
Bring the workflow, decision, or technical constraint that is creating the most friction. We can then decide whether discovery, a focused delivery phase, or a different next step makes sense.
