## 原文

# 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

```bash
# 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](#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`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

### Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://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](https://merchants.google.com/)
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:

```bash
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](https://merchants.google.com/)
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:

```bash
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:**
```json
{
  "name": "accounts/123456789/developerRegistration",
  "gcpIds": ["216141799266"]
}
```

### Step 3: Verify Registration

After registration, v1 endpoints will work:

```bash
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

```bash
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

```bash
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

```bash
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:**
```json
{
  "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

```bash
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:

```bash
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.
