Postman API

by Postman Free tier

The Postman API lets you automate and integrate your API development workflows. Manage workspaces, import and export collections, sync environments, spin up mock servers, trigger monitor runs, and retrieve usage analytics — all via REST. Used for CI/CD integrations, team automation, and platform engineering workflows. The API mirrors Postman's web interface for full programmatic control.
