# 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
