API Testing That Actually Works

We've been fixing broken integrations and catching API failures before they hit production for over eight years. No fancy promises—just thorough testing that keeps your systems running smoothly.

What We Actually Test

  • REST API Endpoints We validate every GET, POST, PUT, DELETE request your app makes. Authentication flows, error handling, response formats—everything gets checked twice.
  • Third-Party Integrations Payment gateways, shipping APIs, CRM connections. When these break, your business stops. We make sure they don't.
  • Data Transformation Your customer data flows between systems constantly. We verify it arrives intact, properly formatted, and exactly where it should be.
  • Performance Under Load APIs that work fine with ten users might crash with a hundred. We test realistic traffic scenarios, not just happy-path cases.
  • Error Recovery Networks fail. Servers go down. We test how your integrations handle these situations and whether they recover gracefully.

How We Approach Integration Testing

Every project is different, but our process stays consistent. We've refined this approach through hundreds of integration projects across Taiwan's tech landscape.

API Discovery and Documentation Review

We start by understanding what you're actually connecting to. Sometimes the documentation is perfect. Often, it's outdated or incomplete.

This phase typically takes 2-3 days, depending on how many integration points you have.

Test Environment Setup

We create isolated testing environments that mirror your production setup without affecting real data or live systems.

Sandbox accounts, test credentials, mock services—whatever it takes to test safely.

Automated Test Development

Manual testing catches some issues. Automated testing catches them consistently, every single time.

We build test suites that run automatically whenever you deploy code changes.

Load and Performance Testing

Real-world traffic patterns are messy and unpredictable. We simulate various load conditions to see where things break.

Better to find bottlenecks in testing than during your biggest sales day of the year.

Documentation and Handover

You get detailed reports on what we found, what we fixed, and how to maintain the test suite going forward.

Plus training for your team on running and updating the tests as your integrations evolve.

Meet Your Testing Specialist

I'm Aldric Bergström, and I've been untangling API integration problems since 2017. Started as a backend developer here in Kaohsiung, then moved into testing when I realized how many integration issues were slipping through to production.

My background spans e-commerce platforms, fintech applications, and logistics systems. Each industry has its own integration challenges, but the fundamentals of good testing remain the same.

What I enjoy most about this work is the detective aspect—figuring out why System A isn't talking properly to System B, and creating tests that prevent it from happening again.

When I'm not debugging API calls, you'll find me exploring Taiwan's mountain trails or experimenting with new testing frameworks.
