API Development Services in Uganda

Secure, well-documented REST and GraphQL APIs that power your web app, mobile app, or connect your systems to third parties. Built to be a stable foundation, not a moving target.

An API is a contract — once your mobile team, web team, or a third-party partner starts building against it, changing it gets expensive. We design APIs carefully upfront: clear endpoints, consistent error handling, proper authentication, and documentation that doesn't go stale. Whether it's powering your own app or exposing data to partners, we build it to last.

What We Do

REST API Design & Development
GraphQL API Development
API Authentication & Authorization (OAuth, JWT, API keys)
Third-Party API Integrations (payments, SMS, logistics)
API Gateway & Rate Limiting Setup
Legacy System API Wrapping
Webhook Systems & Event-Driven APIs
API Documentation (OpenAPI/Swagger)

Our Approach

  • Clear, consistent endpoint design
  • Proper authentication & role-based access control
  • Rate limiting & abuse protection
  • Comprehensive input validation and error responses
  • Auto-generated, always-current API documentation
  • Versioning strategy so changes don't break existing clients
  • Local payment gateway integration (MTN Money, Airtel Money)
  • Monitoring & logging so issues surface immediately

How We Work

1

API Design & Contract

We design the endpoint structure, request/response shapes, and authentication approach as a shared contract before anyone starts building against it.

2

Architecture & Database Design

We design the underlying data model to support the API efficiently, not just patch it together as an afterthought.

3

Development

Built endpoint by endpoint, with validation, error handling, and tests included from the start.

4

Integrations

Payment gateways, SMS providers, or other third-party systems your API needs to connect to.

5

Documentation & Testing

Full OpenAPI/Swagger documentation generated alongside the code, plus automated tests on critical endpoints.

6

Deployment & Handover

Deployed with monitoring and rate limiting in place, with documentation handed to your frontend, mobile, or partner teams.

Frequently Asked Questions

How much does custom API development cost?

A focused API for a single app (10-20 endpoints): $4,000–$8,000. A larger API supporting multiple clients or complex business logic: $10,000–$25,000+. We quote based on scope and integrations needed.

REST or GraphQL — which do we need?

REST is simpler and well-understood — the right default for most projects. GraphQL is worth it when your frontend needs flexible, nested data queries or you're serving multiple client types (web, mobile, partners) with very different data needs. We'll recommend based on your actual use case.

Can you build an API on top of our existing database or legacy system?

Yes. We regularly build API layers on top of existing databases or legacy systems, giving modern apps a clean way to access old data without touching the underlying system directly.

How do you handle API security?

Proper authentication (JWT or OAuth), rate limiting to prevent abuse, input validation on every endpoint, and HTTPS-only communication. For sensitive data, we add additional access logging and encryption where needed.

Will the API scale if our traffic grows?

Yes, if designed for it. We use caching, database indexing, and stateless design so the API can scale horizontally rather than needing a rewrite when usage grows.

Can you integrate our API with MTN Money or Airtel Money?

Yes. We handle the server-side integration: API calls, webhook handling for payment confirmations, and transaction logging, exposed cleanly through your own API.

Do you provide API documentation?

Yes, always. We generate OpenAPI/Swagger documentation alongside development so it stays accurate, giving any team consuming your API a clear, testable reference.

Do you offer ongoing API support?

Yes. Retainers from $1,500/month for monitoring, bug fixes, and new endpoints — important since APIs typically need faster response times than a website when something breaks.
