Overview
The Postman API manages collections, environments, and runs — key-based (an invalid key returns 401, verified).
Quick Start
Collections (replace YOUR_KEY):
curl "https://api.getpostman.com/collections" \
-H "X-Api-Key: YOUR_KEY"
{ "collections": [ { "id": "abc-123", "name": "My Collection" } ] }
Authentication
- Generate an API key in Postman (settings).
- Send it as the
X-Api-Keyheader (invalid → 401, verified).
Rate Limits & Notes
- Free tier with limits (check the docs); paid plans scale.
- Manage collections, environments, mocks, and monitors.
FAQ
Is the Postman API free? Free tier with limits; more is paid.
Why 401? Invalid keys return 401 (verified) — generate a key in Postman settings.
What’s the auth style?
X-Api-Key header.
