APItestingREST

API development platform for designing, testing, documenting, and mocking REST, GraphQL, and gRPC APIs.

Postman offers environment variables, pre-request scripts, test automation with Chai assertions, and collection runners for CI integration. The mock server feature lets frontend teams develop against stable API contracts before the backend is ready.

Useful for backend developers, API designers, and QA engineers. Use it to explore third-party APIs, document internal services, run regression tests, and generate client SDKs from OpenAPI specs.
