This question runs in a pre-configured Salesforce environment - no personal connection required.

Make an HTTP GET request to the DummyJSON API endpoint https://dummyjson.com/products/categories to fetch product categories. Parse the JSON response and return a List of category names (strings). The API returns a JSON array of category objects with slug and name properties - extract the name values. Return an empty list if the API call fails.

Examples:

Output: ['Beauty', 'Fragrances', 'Furniture', 'Groceries', ...] Explanation: The actual category names from the API response
