# How to access additional metafields in V3 Template

> Learn how to access and use additional metafields in your V3 Template implementation

## Overview

In V3 Template, products are fetched using GraphQL. While default product data is automatically included, accessing additional metafields requires three steps:

1. Adding metafields to the `getProductDetailsQuery` function
2. Including metafields in the `transformProductData` function
3. Accessing the metafields in your template's theme.liquid

## Basic Implementation

### Step 1: Modify getProductDetailsQuery

Add your metafields to the GraphQL query in the `getProductDetailsQuery` function:

```javascript theme={null}
getProductDetailsQuery: (recommendation, glood) => {
  return `
    featuredImage {
      url
    }
    handle
    id
    title
    # Add your metafields here
    metafield(namespace: "custom", key: "product_info") {
      value
    }
    # Rest of your existing query
    variants(first: 250) {
      nodes {
        id
        # ... other variant fields
      }
    }
  `
}
```

### Step 2: Update transformProductData

Modify the `transformProductData` function to include your metafields:

```javascript theme={null}
transformProductData: (product) => {
  return {
    featuredImage: product.featuredImage.url
      ? {
          src: product.featuredImage.url,
        }
      : null,
    handle: product.handle,
    id: parseInt(product.id.replace('gid://shopify/Product/', '')),
    title: product.title,
    // Add your metafield transformation
    metafield_value: product.metafield ? product.metafield.value : "N/A",
    // Rest of your existing transformations
    variants: product.variants.nodes.map((variant) => ({
      // ... variant transformations
    }))
  }
}
```

### Step 3: Access in Theme

Use the transformed metafield in your theme.liquid:

```liquid theme={null}
{% raw %}
<div class="_gai-prod-dtls">
  <div class="_gai-full-width">
    <a class="_gai-prod-tit" href="{{ product_url }}">
      {{ product.title }}
    </a>
    {% if product.metafield and product.metafield.value %}
      <p>Extra Info: {{ product.metafield.value }}</p>
    {% else %}
      <p>Information unavailable.</p>
    {% endif %}
  </div>
</div>
{% endraw %}
```

## Practical Example: Product Ratings with Judge.me

### Prerequisites

1. Install Judge.me app on your Shopify store:
   * Go to Shopify App Store and install Judge.me
   * Enable the app integration in your store settings

2. Enable Judge.me in Glood:
   * Navigate to Glood Product Recommendations
   * Go to Settings >> Integrations >> Product Review Apps
   * Enable the Judge.me app integration

After completing the setup, the rating metafields will be available in your GraphQL queries. You can query these metafields using the reviews namespace wherever needed.

To display product ratings in your template, simply use the Judge.me liquid tag:

```liquid theme={null}
{% raw %}
{% product_ratings product_id: product.id %}
{% endraw %}
```
