API Development & Integration Services

Make your systems talk to each other. Our API development and integration services connect websites, apps, and business software into automated workflows - and build the APIs your partners consume.

From payment gateways and SMS to ERPs, logistics, and legacy systems, we design integrations that survive real-world failures: retries, queues, logging, and alerts included.

  • Payment, SMS & ERP integrations
  • Legacy system connectivity
  • Robust error handling & monitoring

Frequently Asked Questions

What is an API and why does my business need one?

An API lets software systems exchange data automatically - your website talking to your accounting system, your app to a payment gateway. Every manual re-entry between systems is time, errors, and money an integration would eliminate.

Can you integrate with old or poorly documented systems?

Usually yes - legacy integration is our specialty. Where no API exists we work with database-level access, file exchanges, or careful automation. We have connected systems whose vendors disappeared years ago.

How do you handle integration failures?

By assuming they will happen: queued retries, idempotent operations, dead-letter handling, and alerting when human attention is needed. The difference between hobby and production integration is what happens when the other side goes down at 3 AM.

Can you build an API for our partners to use?

Yes - public and partner APIs with authentication, rate limiting, versioning, and developer documentation. We design APIs we would want to consume: predictable, well-errored, and stable across versions.

What does an integration project cost?

Simple gateway integrations are quick, fixed-price work; multi-system ERP synchronization is a larger project. After mapping your systems and data flows we quote per integration - and often find quick wins that pay for the rest.
