API & Integration Testing That Actually Works
We help Thailand's growing tech companies build reliable systems by thoroughly testing their APIs and integrations before problems reach production
Deep Testing Beyond Surface Checks
Most API testing focuses on whether endpoints return 200 responses. But real-world systems break in more subtle ways. We've seen payment APIs that work perfectly in isolation but fail when processing concurrent transactions. Database integrations that handle small datasets beautifully but crash under realistic loads.
Our approach starts with understanding how your systems actually get used. We create test scenarios based on real traffic patterns, not just happy-path documentation examples.
- Boundary testing with edge cases your users will inevitably find
- Concurrent request testing to catch race conditions early
- Data validation testing with malformed and unexpected inputs
- Integration point testing where different systems connect
Three Core Areas Where We Help
API Testing & Validation
We test REST APIs, GraphQL endpoints, and microservices architectures with real-world scenarios that matter to your business operations.
- Response validation and schema compliance
- Authentication and authorization testing
- Rate limiting and error handling verification
- Version compatibility across API updates
System Integration Testing
End-to-end testing of how your systems talk to each other, from CRM connections to payment gateway integrations.
- Data flow validation between systems
- Third-party service integration testing
- Database synchronization verification
- Webhook and callback functionality testing
Performance & Load Testing
Testing how your APIs perform under real traffic loads, helping you scale confidently as your business grows.
- Realistic load simulation and stress testing
- Response time optimization recommendations
- Bottleneck identification and analysis
- Scalability planning and capacity testing
