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
Sign in or create an account at maton.ai Go to maton.ai/settings Copy your API key
Finding Your Merchant Center Account ID
Your Merchant Center account ID is a numeric identifier. To find it: Log in to Google Merchant Center 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: Log in to Google Merchant Center 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 = 'your-email@example.com' # 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.

Notes
Developer registration required - You must complete Developer Registration once per Merchant Center account before using v1 endpoints Product IDs use the format contentLanguage~feedLabel~offerId (e.g., en~US~sku123) Products can only be inserted/updated/deleted in data sources with input: "API" type After inserting/updating a product, it may take several minutes before the processed product appears Monetary values use micros (divide by 1,000,000 for actual value) Local inventories only work for products with LOCAL channel (not ONLINE) The Promotions API requires your account to be enrolled in the Promotions program List Sub-accounts only works for multi-client accounts (MCAs) IMPORTANT: When using curl commands, use curl -g when URLs contain brackets 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
Error Handling
StatusMeaning400Invalid request or missing Google Merchant connection401Invalid/missing Maton API key, or GCP project not registered (see Developer Registration)403Permission denied - account not enrolled in required program or feature not available404Resource not found429Rate limited4xx/5xxPassthrough error from Google Merchant API
Common Errors
"GCP project is not registered": You need to complete developer registration. See Developer Registration section. "The caller does not have access to the accounts": The specified account ID is not accessible with your OAuth credentials. Verify you have access to the Merchant Center account. "Promotion program not enabled": Your Merchant Center account is not enrolled in the Promotions program. Enable it in Merchant Center settings. "This method can only be accessed by multi-client accounts": You're calling an endpoint (like listSubaccounts) that only works for multi-client accounts (MCAs). "Mismatched channel": You're trying to access local inventories for an ONLINE product. Local inventories only work with LOCAL channel products.
Troubleshooting: API Key Issues
Check that the MATON_API_KEY environment variable is set: echo $MATON_API_KEY 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
Ensure your URL path starts with google-merchant. For example: Correct: https://gateway.maton.ai/google-merchant/products/v1/accounts/{accountId}/products Incorrect: https://gateway.maton.ai/products/v1/accounts/{accountId}/products
Troubleshooting: 401 GCP Project Not Registered
If you see an error like "GCP project is not registered with the merchant account": Complete developer registration - See Developer Registration section Get your account ID from Merchant Center UI (in the URL after ?a=) Call the registerGcp endpoint with your account ID and email After successful registration, retry your original request
