Postman provides a set of tools for sending API requests, managing sensitive data, and capturing live traffic for inspection and debugging. This section covers the core workflows for working with APIs in Postman.

Send requests

The Postman request builder lets you construct and send HTTP requests to any API endpoint, inspect the response, and iterate quickly during development or testing. You can add parameters, headers, body data, and authentication to your requests, and organize them into collections for reuse. Postman also includes dedicated clients for protocols beyond HTTP, including GraphQL, gRPC, WebSocket, MQTT, AI models, MCP servers, and more.

To learn more, see Send API requests and get response data in Postman.

Collections

Postman Collections group related API requests so you can save, organize, share, and run them. You can create a collection from scratch or from a template, add folders to group requests, and restore a collection to an earlier state. Collections are based on the open source collection format, which you can use to generate SDKs, documentation, and mock servers.

To learn more, see Create and manage request collections in Postman.

Native Git

Native Git lets you develop APIs in a local Git repository and sync them to Postman Cloud when the work is ready to share. In Local View, your collections, environments, specs, and project files live alongside your code. In Cloud View, they’re the shared version your team can review and rely on. You can also automate pushes to Postman Cloud with CI/CD. Native Git requires the Postman desktop app.

Agent Mode

Agent Mode provides AI-powered automation that helps you work faster with Postman. Describe what you want to do in plain language—send requests, fix errors, update tests, build Flows—and Agent Mode handles the implementation. It runs locally and operates only within Postman.

To learn more, see Agent Mode.

Agent Mode on Cloud

Agent Mode on Cloud is an AI-powered agent that handles longer engineering tasks autonomously. Connect it to your codebase, APIs, and repositories, and it can run complex workflows—updating code, running tests, and executing Postman Collections—in a secure cloud sandbox. It reports results back for your review before anything is merged or published.

To learn more, see Agent Mode on Cloud.

Context Graph

Postman Context Graph (also known as Agent Context) maps your organization’s APIs, deployments, database schemas, external services, and teams into a single dependency graph. Use it to answer questions about how your services relate to each other, and to give AI agents grounded, queryable context about your architecture. You can query Context Graph from an MCP client.

To learn more, see About Postman Context Graph and Query Context Graph with an MCP client.

Postman Vault

Postman Vault gives you a secure place to store sensitive values such as API keys and passwords as vault secrets. Secrets stored in your local vault stay on your machine and are never synced to Postman’s servers. You can also connect Postman Vault to external secret managers to reference managed secrets without storing them in Postman directly.

To learn more, see Store secrets in Postman Vault.

Capture API traffic

Postman can act as a proxy or use the Postman Interceptor browser extension to intercept HTTP and HTTPS traffic between a client and a server. Capturing traffic lets you record real requests as they happen, save them to a collection, and inspect or replay them for debugging. You can also use the proxy or Interceptor to capture and sync cookies to the Postman cookie jar.
