Design, test, and govern APIs — now with AI agents in the loop
A multi-protocol client with collections, environments, variables, and reusable requests that works for local debugging and for driving automated test suites.
Generates assertions automatically, supports data-driven runs with exported datasets, and executes tests locally, in the cloud, or from CI pipelines via the Postman CLI.
Agent Mode, the Postman CLI agent skills, and a Model Context Protocol server let coding assistants build collections, write tests, and trigger API workflows from inside the editor.
A structured, queryable map of an organization's APIs, collections, and dependencies that lets agents find the right service and understand what a schema change would break.

AI agents qualify leads, answer routine questions, route to the right teammate and follow up automatically when conversations go quiet.
Track tags, custom fields, lead status and lifecycle stage per contact, and move deals through a pipeline without a separate CRM.
Reach thousands of customers with one message, and capture new leads directly from social ads and website links.
