Gumroad

Access the Gumroad API with managed OAuth authentication. Manage products, view sales, verify licenses, and set up webhooks for your digital storefront.

Quick Start

# Get current user info
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/gumroad/v2/user')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://gateway.maton.ai/gumroad/v2/{resource}

The gateway proxies requests to api.gumroad.com/v2 and automatically injects your OAuth token.

Authentication

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

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

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. Copy your API key

Connection Management

Manage your Gumroad OAuth connections at https://ctrl.maton.ai.

req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')

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": "e1a4444f-2bb8-4e09-9265-3afe71b74b1f",
    "status": "ACTIVE",
    "creation_time": "2026-02-08T06:22:48.654579Z",

    "metadata": {}
  }
}

Open the returned url in a browser to complete OAuth authorization.

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 Gumroad connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/gumroad/v2/products')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', 'e1a4444f-2bb8-4e09-9265-3afe71b74b1f')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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