Postman

Browse and manage Postman workspaces, collections, and environments via the Postman API.

Manual setup 11 tools

Overview

Connect Postman to let AI clients browse and manage your workspaces, collections, and environments programmatically.

Prerequisites

  • A Postman account with API access
  • A stackgate.ai account

Getting credentials

  1. Sign in to Postman.
  2. Open Settings → API keys and generate a new API key. Copy it somewhere safe.
  3. In stackgate.ai, open Integrations → Postman.
  4. Click Activate and paste your API key.
  5. If you use a Postman EU Enterprise account, set the API base URL to https://api.eu.postman.com.

See the Postman API authentication docs for key management and permissions.

Using with AI clients

  • Dedicated endpoint: POST /mcp/postman with a Sanctum bearer token
  • Private gateway: one config for all integrations — use postman__* namespaced tools

See Documentation for HTTP authentication and private gateway setup.

Troubleshooting

  • 422 integration not configured — complete the credential form in My Integrations with your API key.
  • 401 Unauthorized — regenerate the API key in Postman and update your integration credentials.
  • 403 Forbidden — your Postman plan or region may not include the requested feature.
  • 429 Too many requests — Postman rate limits list endpoints to 10 calls per 10 seconds; wait before retrying.
  • Collection or environment not found — use the full UID (userId-itemId) from list tools, not the bare item UUID.
