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.
