Enterprise API Testing & Automation Services in Bangalore
We validate the reliability, performance, and security of RESTful, GraphQL, and gRPC APIs. Automate backend regression suites, verify contract compliance with Pact, and ensure sub-50ms endpoint latencies before production rollout.
Complete API Testing & Automation Capabilities
Validating endpoints for schema conformity, data integrity, edge cases, and high-throughput security.
Functional & Schema Validation QA
Automated verification of JSON/XML schemas, HTTP status codes, header configurations, and payload boundary values against OpenAPI specs.

CI/CD Gate Integration
Integrating Newman and REST Assured into deployment pipelines to block broken backend builds automatically.
Enterprise API QA Standards
Rigorous standards guaranteeing sub-50ms latencies and zero breaking API changes.
100% Contract Compliance
Zero tolerance for unexpected schema deviations or removed fields that could break mobile apps or frontend web.
OWASP API Top 10 Hardened
Complete verification that all endpoints enforce strict authorization checks preventing data leaks.
Sub-50ms Internal API Latency
Benchmarking microservice-to-microservice endpoints to guarantee response latency under 50ms.
Strict Idempotency Validation
Verifying that repeated PUT, DELETE, and payment POST requests with idempotency keys do not cause duplicate operations.
Robust Error Payload Schema
Ensuring all 4xx and 5xx errors return structured, machine-readable JSON payloads with descriptive error codes.
Automated Smoke Tests < 60s
Core API smoke suite executing in under 60 seconds on every microservice code commit.
Featured API Testing Case Study
Automating contract testing across 45 microservices for a digital banking platform.
Pact Contract & REST Assured Automation for Core Banking APIs
Implemented automated contract testing with Pact and REST Assured across 45 microservices handling core accounts, loans, and payments. Caught 28 breaking schema changes in CI before deployment, reducing integration defects to zero.
