Google Merchant Center

Access the Google Merchant Center API with managed OAuth authentication. Manage products, inventories, promotions, data sources, and reports for Google Shopping.

Quick Start

# List products in your Merchant Center account
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/google-merchant/products/v1/accounts/{accountId}/products')
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/google-merchant/{sub-api}/{version}/accounts/{accountId}/{resource}

The Merchant API uses a modular sub-API structure. Replace:

• {sub-api} with the service: products, accounts, datasources, reports, promotions, inventories, notifications, conversions
• {version} with v1
• {accountId} with your Merchant Center account ID

The gateway proxies requests to merchantapi.googleapis.com and automatically injects your OAuth token.

Important: The v1 API requires one-time developer registration. See Developer Registration section.

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

Finding Your Merchant Center Account ID

Your Merchant Center account ID is a numeric identifier. To find it:

1. Log in to Google Merchant Center
2. Look at the URL - it contains your account ID: https://merchants.google.com/mc/overview?a=ACCOUNT_ID

Developer Registration

Important: Before using the v1 API, you must complete a one-time developer registration to associate your account with the API.

Step 1: Get Your Account ID

Option A: Try fetching via API first

Try listing accounts using the v1beta endpoint. If this works, you can get your account ID automatically:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/google-merchant/accounts/v1beta/accounts')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
try:
    result = json.load(urllib.request.urlopen(req))
    for account in result.get('accounts', []):
        print(f"Account ID: {account['accountId']}, Name: {account['accountName']}")
except Exception as e:
    print(f"v1beta not available - use Option B to get your account ID manually")
EOF

Option B: From Merchant Center UI (if Option A fails)

If the v1beta endpoint is unavailable or returns an error:

1. Log in to Google Merchant Center
2. Your account ID is in the URL: https://merchants.google.com/mc/overview?a=YOUR_ACCOUNT_ID

For example, if your URL is https://merchants.google.com/mc/overview?a=123456789, your account ID is 123456789.

Step 2: Register for API Access

Call the registerGcp endpoint with your account ID and email:

python <<'EOF'
import urllib.request, os, json

account_id = 'YOUR_ACCOUNT_ID'  # From Step 1
developer_email = '[email protected]'  # Your Google account email

data = json.dumps({'developerEmail': developer_email}).encode()
req = urllib.request.Request(
    f'https://gateway.maton.ai/google-merchant/accounts/v1/accounts/{account_id}/developerRegistration:registerGcp',
    data=data,
    method='POST'
)
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')

result = json.load(urllib.request.urlopen(req))
print(json.dumps(result, indent=2))
EOF

Response:

{
  "name": "accounts/123456789/developerRegistration",
  "gcpIds": ["216141799266"]
}

Step 3: Verify Registration

After registration, v1 endpoints will work:

python <<'EOF'
import urllib.request, os, json
account_id = 'YOUR_ACCOUNT_ID'
req = urllib.request.Request(f'https://gateway.maton.ai/google-merchant/accounts/v1/accounts/{account_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Note: Registration only needs to be done once per Merchant Center account. After registration, all v1 endpoints will work for that account.

Connection Management

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

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=google-merchant&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

Create Connection

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'google-merchant'}).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

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": "00726960-095e-47e2-92e6-6e9cdf3e40a1",
    "status": "ACTIVE",
    "creation_time": "2026-02-07T06:41:22.751289Z",
    "last_updated_time": "2026-02-07T06:42:29.411979Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "google-merchant",
    "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 Google Merchant 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/google-merchant/products/v1/accounts/123456/products')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '00726960-095e-47e2-92e6-6e9cdf3e40a1')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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