name: api-gateway description: | API gateway for calling third-party APIs with managed auth. Use this skill when users want to interact with external services like Slack, HubSpot, Salesforce, Google Workspace, Stripe, and more. compatibility: Requires network access and valid Maton API key metadata: author: maton version: "1.0"

API Gateway

Passthrough proxy for direct access to third-party APIs using managed auth connections. The API gateway lets you call native API endpoints directly.

Quick Start

# Native Slack API call
curl -s -X POST "https://gateway.maton.ai/slack/api/chat.postMessage" -H "Content-Type: application/json" -H "Authorization: Bearer $MATON_API_KEY" -d '{"channel": "C0123456", "text": "Hello from gateway!"}'

IMPORTANT: If you receive a 500 Internal Server Error, this does NOT mean the service is unsupported. The most common cause is an expired OAuth refresh token (connections older than 1 month). See the "Troubleshooting 500 Internal Server Error" section below to create a new connection and retry with the new connection ID.

Base URL

https://gateway.maton.ai/{app}/{native-api-path}

Replace {app} with the service name and {native-api-path} with the actual API endpoint path.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

The API gateway automatically injects the appropriate OAuth token for the target service.

Environment Variable: You can set your API key as the MATON_API_KEY environment variable:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Click the copy button on the right side of API Key section to copy it

Connection Management

Connection management uses a separate base URL: https://ctrl.maton.ai

List Connections

curl -s -X GET "https://ctrl.maton.ai/connections?app=slack&status=ACTIVE" -H "Authorization: Bearer $MATON_API_KEY"

Query Parameters (optional): - app - Filter by service name (e.g., slack, hubspot, salesforce) - status - Filter by connection status (ACTIVE, PENDING, FAILED)

Response:

{
  "connections": [
    {
      "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80",
      "status": "ACTIVE",
      "creation_time": "2025-12-08T07:20:53.488460Z",
      "last_updated_time": "2026-01-31T20:03:32.593153Z",
      "url": "https://connect.maton.ai/?session_token=5e9...",
      "app": "slack",
      "metadata": {}
    }
  ]
}

Create Connection

curl -s -X POST "https://ctrl.maton.ai/connections" -H "Content-Type: application/json" -H "Authorization: Bearer $MATON_API_KEY" -d '{"app": "slack"}'

Get Connection

curl -s -X GET "https://ctrl.maton.ai/connections/{connection_id}" -H "Authorization: Bearer $MATON_API_KEY"

Response:

{
  "connection": {
    "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=5e9...",
    "app": "slack",
    "metadata": {}
  }
}

Open the returned URL in a browser to complete OAuth.

Delete Connection

curl -s -X DELETE "https://ctrl.maton.ai/connections/{connection_id}" -H "Authorization: Bearer $MATON_API_KEY"

Specifying Connection

If you have multiple connections for the same app, you can specify which connection to use by adding the Maton-Connection header with the connection ID:

curl -s -X POST "https://gateway.maton.ai/slack/api/chat.postMessage" -H "Content-Type: application/json" -H "Authorization: Bearer $MATON_API_KEY" -H "Maton-Connection: 21fd90f9-5935-43cd-b6c8-bde9d915ca80" -d '{"channel": "C0123456", "text": "Hello!"}'

If omitted, the gateway uses the default (oldest) active connection for that app.

Code Examples

JavaScript (Node.js)

const response = await fetch('https://gateway.maton.ai/slack/api/chat.postMessage', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Authorization': `Bearer ${process.env.MATON_API_KEY}`
  },
  body: JSON.stringify({ channel: 'C0123456', text: 'Hello!' })
});

Python

import os
import requests

response = requests.post(
    'https://gateway.maton.ai/slack/api/chat.postMessage',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    json={'channel': 'C0123456', 'text': 'Hello!'}
)

Error Handling

Errors from the target API are passed through with their original status codes and response bodies.

Troubleshooting 500 Internal Server Error

IMPORTANT: A 500 Internal Server Error does NOT mean the service is unsupported. If the app is listed in the Supported Services table above, the error is likely due to an expired OAuth refresh token.

When you receive a 500 Internal Server Error, ALWAYS follow these steps before concluding there is an issue:

Connections that have been active for more than 1 month may have expired OAuth refresh tokens. To resolve:

1. Create a new connection for the app: bash curl -s -X POST "https://ctrl.maton.ai/connections" -H "Content-Type: application/json" -H "Authorization: Bearer $MATON_API_KEY" -d '{"app": "APP_NAME"}'

2. Get the OAuth URL by calling the GET connection endpoint with the new connection ID from step 1: bash curl -s -X GET "https://ctrl.maton.ai/connections/NEW_CONNECTION_ID" -H "Authorization: Bearer $MATON_API_KEY"

3. Share the returned url with the user and ask them to complete the OAuth flow in their browser.

4. After the user completes OAuth, retry the original request using the new connection ID via the Maton-Connection header: bash curl -s -X GET "https://gateway.maton.ai/APP_NAME/..." -H "Authorization: Bearer $MATON_API_KEY" -H "Maton-Connection: NEW_CONNECTION_ID"

5. Once the new connection status is ACTIVE and working, ask the user if they want to delete the old connection: bash curl -s -X DELETE "https://ctrl.maton.ai/connections/OLD_CONNECTION_ID" -H "Authorization: Bearer $MATON_API_KEY"

Rate Limits

• 10 requests per second per account
• Target API rate limits also apply

Notes

• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) to disable glob parsing
• IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

Tips

1. Use native API docs: Refer to each service's official API documentation for endpoint paths and parameters.

2. Headers are forwarded: Custom headers (except Host and Authorization) are forwarded to the target API.

3. Query params work: URL query parameters are passed through to the target API.

4. All HTTP methods supported: GET, POST, PUT, PATCH, DELETE are all supported.

5. QuickBooks special case: Use :realmId in the path and it will be replaced with the connected realm ID.
