Read More →OpenMalo validates the functionality, security, performance, and reliability of your APIs — using Postman, REST Assured, k6, and Burp Suite Pro to deliver comprehensive testing from functional endpoint validation and Pact contract testing to OWASP API Security Top 10 assessment and load testing under realistic concurrent traffic.
Systematic endpoint-by-endpoint validation of request/response schemas, status codes, error handling, pagination, filtering, and business logic — using Postman collections or REST Assured Java test suites.
Load and stress testing of API endpoints using k6 — measuring throughput, p95/p99 response times, and error rates under realistic concurrent load modelled from production traffic data.
Manual and automated security assessment covering all 10 OWASP API Security risks using Burp Suite Pro — broken object-level authorisation, mass assignment, excessive data exposure, and rate limiting bypass.
Pact contract testing ensuring API providers remain compatible with all consumers through independent deployment — critical for microservices architectures where teams ship independently.
Multi-service integration flow testing validating data transformation accuracy, message sequencing, error propagation, retry behaviour, and webhook delivery between API-connected systems.
Newman (Postman CLI), REST Assured, or pytest-based automated API test suites integrated into GitHub Actions or Azure DevOps — blocking deployments when API tests fail.
Validation of actual API behaviour against the OpenAPI 3.0 specification using Dredd — identifying drift between documented and implemented behaviour that causes integration failures downstream.
Automated regression suites detecting breaking changes across API versions — maintaining backwards compatibility and preventing integration failures for existing API consumers.
APIs are the nervous system of modern software — a defective API breaks every system that depends on it. In a microservices architecture, a single API regression can cascade into failures across your entire platform. OpenMalo tests APIs with the rigour their critical role demands — using Postman and REST Assured for functional coverage, k6 for performance, Burp Suite Pro for OWASP API security, and Pact for contract testing across service boundaries.
Our team has tested APIs for Australian payment platforms subject to PCI DSS, healthcare systems governed by FHIR and AHPRA requirements, government services under ASD Essential Eight, and high-volume SaaS products serving enterprise clients. Every API testing engagement includes OpenAPI specification validation, CI/CD integration as a deliverable, and a defect report with severity ratings and specific remediation code guidance.

We review your OpenAPI 3.0 specification, understand the API's role in the system architecture, identify test scope and authentication flows, and define test data requirements before any testing begins.
Systematic testing of every endpoint in Postman — happy paths, error scenarios, boundary conditions, authentication flows, pagination, and business logic — with full results documentation in Jira or TestRail.
OWASP API Security Top 10 assessment using Burp Suite Pro and k6 performance load testing under realistic concurrent load — with APM instrumentation capturing response time percentiles and error rates.
