API Gateway

Passthrough proxy for direct access to third-party APIs using managed OAuth connections, provided by Maton. The API gateway lets you call native API endpoints directly.

Quick Start

# Native Slack API call
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'channel': 'C0123456', 'text': 'Hello from gateway!'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/slack/api/chat.postMessage', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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.

IMPORTANT: The URL path MUST start with the connection's app name (eg. /google-mail/...). This prefix tells the gateway which app connection to use. For example, the native Gmail API path starts with gmail/v1/, so full paths look like /google-mail/gmail/v1/users/me/messages.

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

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=slack&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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",
      "method": "OAUTH2",
      "metadata": {}
    }
  ]
}

Create Connection

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'slack'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Request Body:

• app (required) - Service name (e.g., slack, notion)
• method (optional) - Connection method (API_KEY, BASIC, OAUTH1, OAUTH2, MCP)

Get Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'channel': 'C0123456', 'text': 'Hello!'}).encode()
req = urllib.request.Request('https://gateway.maton.ai/slack/api/chat.postMessage', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

1. Verify the API key is valid by listing connections:

python <<'EOF'

import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

1. Verify your URL path starts with the correct app name. The path must begin with /google-mail/. For example:

• Correct: https://gateway.maton.ai/google-mail/gmail/v1/users/me/messages
• Incorrect: https://gateway.maton.ai/gmail/v1/users/me/messages

1. Ensure you have an active connection for the app. List your connections to verify:

python <<'EOF'

import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=google-mail&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Server Error

A 500 error may indicate an expired OAuth token. Try creating a new connection via the Connection Management section above and completing OAuth authorization. If the new connection is "ACTIVE", delete the old connection to ensure the gateway uses the new one.

Rate Limits

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

Notes

• When using curl with URLs containing brackets (fields[], sort[], records[]), use the -g flag to disable glob parsing
• When piping curl output to jq, environment variables may not expand correctly in some shells, which can cause "Invalid API key" errors

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.
