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

Make an HTTP GET request to the DummyJSON Products API to retrieve a single product by its ID and return the product title. The endpoint format is https://dummyjson.com/products/{id} where {id} is the product ID parameter. If the product ID is null, return null.

Examples:

Input: productId = 1 Output: "Essence Mascara Lash Princess" Explanation: Product ID 1 returns a product with this title Input: productId = 5 Output: "Essence Mascara Lash Princess" Explanation: Product ID 5 returns a product with this title Input: productId = null Output: null Explanation: Null input should return null
