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

Call a product API to retrieve products for a given category. Return an empty list when the category is null or blank. The API endpoint is /api/products?category={category} and returns JSON with a products array containing objects with id, name, and price fields.

Examples:

List<Map<String, Object>> electronics = fetchCategoryProducts('electronics');
// Results: List of product maps from API response

List<Map<String, Object>> empty = fetchCategoryProducts(null);
// Results: []

Hints:

  • Validate the category parameter before making the API call
  • Use HttpRequest and HttpResponse classes for the API integration
  • Parse the JSON response to extract the products array
  • Handle API errors gracefully by returning an empty list
