The POST /orders/{orderId}/amendments endpoint is designed to allow Grubtech to notify the aggregator platform about eligible amendments for a specific order. This endpoint is particularly useful when Grubtech suggests changes to an order, such as item substitutions, modifications, or additions, and requires confirmation from the customer through the aggregator platform. By providing a structured way to communicate amendments, Grubtech enhances order accuracy and customer satisfaction, ensuring that modifications align with customer preferences.
