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

Make an HTTP callout to the DummyJSON API endpoint https://dummyjson.com/products/category/{category} to fetch products by category and return a list of product titles. Handle errors gracefully and return an empty list if the request fails.

Examples:

Input: category = 'smartphones' Output: ['iPhone 9', 'iPhone X', 'Samsung Universe 9', 'OPPOF19', 'Huawei P30'] Explanation: Returns titles of all smartphones from the API Input: category = 'laptops' Output: ['MacBook Pro', 'Samsung Galaxy Book', 'Microsoft Surface Laptop 4', 'Infinix INBOOK', 'HP Pavilion 15-DK1056WM'] Explanation: Returns titles of all laptops from the API Input: category = 'nonexistent' Output: [] Explanation: Returns empty list for invalid categories
