# Step 5: Retrieve Subcategories

Next, drill down into the **Social Media** category to find the **Social and Messaging Usage** subcategory.

<RequestExample>
  ```bash theme={null}
  curl -X GET "https://api.globalwebindex.com/v2/categories/500?include=children" \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer YOUR_API_KEY"
  ```
</RequestExample>

<ResponseExample>
  ```json Response theme={null}
  { 
      "category": { 
          "id": "500", 
          "name": "Social Media", 
          "child_categories": [ 
              { 
                  "id": "520", 
                  "name": "Social and Messaging Usage" 
              }, 
              ... 
          ] 
      } 
  }
  ```
</ResponseExample>

From the response, note the `id` for the **Social and Messaging Usage** subcategory: `520`.
