What is API testing?
API testing validates the layer your users never see: the requests, responses, contracts and failure modes behind the interface. Testriq tests REST and GraphQL APIs for correctness, security and scale under the ISO 29119 framework, and embeds the suite into your CI/CD pipeline so regressions surface before release.
End-to-End API QA for Global Markets
We provide specialized API testing tailored for global markets, including the US, UK, and EU, ensuring your services are secure and high-performing.
REST API Testing
Our industry-standard REST testing validates HTTP methods and ensures precise JSON or XML data. We verify that every endpoint meets your business logic and performance goals.
The 2026 API Testing Landscape: Navigating Global Challenges
In 2026, API testing is no longer just about checking status codes like 200 OK or 404 Not Found. Modern API testing manages escalating risks within complex digital ecosystems.
1. Escalating API Security Risks
99% of organizations encountered API security issues last year. 95% of attacks originate from verified sessions, exposing gaps in token handling.
2. Complex Distributed Architectures
Modern APIs function within event-driven landscapes. We use ISO 29119-3 standards to define multi-system dependencies and ensure reliability.
3. Schema Changes and Test Stability
We apply ISO 29119-4 design techniques to simplify schema maintenance. boundary values and combinations keep suites stable as contracts evolve.
Standard-Aligned QA Methodology: The Testriq Way
Our API testing follows the ISO 29119 series. Global firms recognize and trust this traceable process model.
Plan & Analyze Risks
We analyze risks to identify critical endpoints. This follows the risk-based approach defined in ISO 29119 Part 2.
Key Activities:
Keyword-Driven & Model-Based Testing (MBT)
We implement Keyword-Driven and Model-Based Testing (MBT). This approach follows the new ISO 29119-5:2024 standard to ensure your automation remains scalable. This allows for structured automated test generation, ensuring your suite remains maintainable as your API portfolio grows.
