API Testing That Actually Works

We've been debugging integration nightmares since 2018. Our testing approach finds the problems before your users do — and we explain everything in plain English.

Seven Years of Real-World Testing

Most testing companies give you reports full of technical jargon. We focus on what actually matters: does your API work reliably? Can your systems talk to each other? Will everything still function when traffic spikes during Chinese New Year?

  • Performance Under Pressure: We simulate real Taiwan market conditions, including holiday traffic surges and mobile network variations.
  • Integration Reality Checks: Your payment gateway might work perfectly until it needs to handle traditional Chinese characters — we catch those details.
  • Plain English Reporting: No confusing technical mumbo-jumbo. You get clear explanations of what's broken and exactly how to fix it.
  • Taiwan Market Expertise: We understand local payment systems, government regulations, and cultural expectations that affect system design.

What We Actually Test

Every business has different integration challenges. Here's how we tackle the most common ones — and the weird edge cases that nobody thinks about until 3 AM on a Sunday.

API

API Reliability Testing

We hammer your APIs with realistic loads and unusual scenarios. What happens when someone sends traditional characters in a field expecting simplified? When mobile connections drop mid-transaction? We find out before your customers do.

Integration Validation

Your CRM talks to your inventory system, which talks to your payment processor. Beautiful — until one of them gets updated. We test these connections thoroughly and document exactly how data flows between systems.

Security & Compliance

Taiwan's data protection regulations aren't optional. We verify your systems handle personal information correctly, check authentication flows, and ensure your APIs can't be easily exploited by determined troublemakers.

How We Actually Work

No mysterious black boxes or weeks of silence. Here's exactly what happens from day one to deployment — and why we do things this way.

1

Discovery & Planning

We map out your system architecture and identify potential failure points. This isn't just technical documentation — we want to understand your business workflows and where breakdowns would hurt most.

2

Test Design & Setup

We create realistic test scenarios based on your actual usage patterns. If your system gets hammered during lunch hours, we simulate that. If you process bulk uploads monthly, we test for that too.

3

Execution & Analysis

We run comprehensive tests while monitoring system behavior in real-time. When something breaks (and something always does), we dig deep to understand root causes, not just symptoms.

4

Clear Reporting

You get actionable recommendations in plain language. We prioritize issues by business impact and provide specific steps to resolve each problem. No technical jargon, no vague suggestions.

Why Businesses Choose Sagionet

We saved three weeks of debugging headaches when Sagionet caught a character encoding issue that would have broken our customer portal during the Mid-Autumn Festival rush. Their testing found problems our internal team missed completely — and they explained everything clearly enough that we could fix it ourselves.
