Public product context
What the product does.
Postman puts API exploration, testing and collaboration in one workspace. Its API client supports HTTP, GraphQL, gRPC, WebSocket and MQTT, so teams can work across different services without switching tools for each protocol.
Compose, send, inspect
Developers configure authentication, request parameters and bodies, then inspect responses and debug failures in the same interface.
Turn exploration into a workflow
Pre-request and post-response scripts add assertions and repeatable steps. Collections and environments organize related requests and their configuration.
A product used throughout development
The interface serves both a quick one-off request and ongoing API work shared with a team.
