What is Postman?

Postman is a unified platform for designing, testing, distributing, documenting, and monitoring APIs. It provides tools to organize API requests, collaborate across teams, and automate testing workflows throughout the API lifecycle. The platform unifies API specifications, code, and documentation while supporting contract-first governance and bi-directional Git synchronization. Postman integrates with CI/CD pipelines to catch failures at commit time and includes governance features for automated compliance scanning and encrypted secret management.
