API Development

We design and build REST APIs and integration layers that connect your software to the tools you already run — payment gateways, SMS/WhatsApp providers, accounting software, mapping services, and other third-party platforms. This covers both building an API for your own product to expose, and integrating your systems with someone else's.

Scope

What This Includes

  • REST API design and documentation for your own product or internal systems
  • Third-party integrations — payment gateways, WhatsApp/SMS, accounting, mapping and logistics APIs
  • Authentication and access control (API keys, OAuth, rate limiting)
  • Webhook setup for real-time data sync between systems
  • API performance monitoring and versioning strategy
  • Migration support for legacy APIs to modern standards
How We Work

Our Standard Delivery Process

The same process we run on every engagement — including api development.

01

Discover

We learn the business, the goals and what the system actually needs to do.

02

Planning

Scope, timeline and pricing get fixed in writing before any work begins.

03

Design

We map the structure and interface before a single line of code is written.

04

Development

Engineers build the system, with weekly progress updates so nothing is a surprise.

05

Testing

The system is reviewed and checked against the original requirements before it goes live.

06

Deployment

We move the system into production and confirm it runs as intended.

07

Support

Training and documentation come standard, plus a year of free updates and support.
