Professional API and Integration Testing

We help Vietnamese businesses ensure their digital systems work flawlessly together. From simple API validations to complex enterprise integrations, our testing approach catches issues before they impact your customers.

Why Integration Testing Matters

Think about the last time an app crashed right when you needed it most. That frustrating moment often happens because different software pieces don't communicate properly.

In Vietnam's rapidly digitizing market, businesses lose customers and revenue when their systems fail to integrate smoothly. We've seen companies struggle with payment gateways that randomly reject transactions, inventory systems that don't sync with online stores, and mobile apps that can't connect to backend services.

Our systematic testing approach identifies these problems during development, not after your customers encounter them. We simulate real-world conditions and user behaviors to ensure your integrations perform reliably under pressure.

Our Testing Services

API Functionality Testing

We verify that your APIs respond correctly to various inputs and handle edge cases gracefully. This includes testing authentication flows, data validation, error handling, and response formatting.

  • Request and response validation
  • Authentication and authorization testing
  • Data format verification
  • Error handling assessment

Performance and Load Testing

Your APIs need to perform well under real-world traffic conditions. We simulate high-volume usage scenarios to identify bottlenecks before they affect your users.

  • Load capacity analysis
  • Response time optimization
  • Concurrent user simulation
  • Resource usage monitoring

Security Testing

Security vulnerabilities in APIs can expose sensitive business and customer data. We conduct thorough security assessments to protect your systems from common attack vectors.

  • Authentication bypass testing
  • Data injection attack prevention
  • Access control verification
  • Encryption validation

Third-Party Integration Testing

When your system depends on external services like payment processors, social media platforms, or shipping providers, we ensure these connections work reliably.

  • Payment gateway integration
  • Social media API connections
  • Shipping and logistics APIs
  • Government service integrations
