This question runs in a pre-configured Salesforce environment - no personal connection required.
Given a cart ID, fetch the cart details from the DummyJSON API at https://dummyjson.com/carts/{cartId} and return the total price of the cart. The API returns a JSON object containing a "total" field with the cart total value. Return null for null or non-positive cart IDs. Return null if the API request fails or returns a non-200 status code.
Examples:
Input: cartId = 1
Output: The total value from cart 1 (e.g., 2328.0)
Input: cartId = null
Output: null
Explanation: Null input returns null
Input: cartId = 0
Output: null
Explanation: Non-positive cart ID returns null
