16 Cancel Operation
16.1 Introduction
This operation allows cancelling a previously submitted order. In case of EO product orders this operation triggers the cancellation of the order items; in case of subscriptions it means to unsubscribe
from them.
The cancellation of product order items is not always possible, and then the operation returns the following results:
– “success”, if all items can be cancelled; – “incomplete”, in case of partial cancellation
The cancellation is not a real-time process, and then the operation is asynchronous.
