Which of the following is an example of an Incoming Message?

An Incoming Message in the context of a messaging interface typically refers to a message that is received by a system, often as a request to perform a specific action or to process certain information. The action of creating an order represents a request made to the system, which involves receiving and processing data about the order. When a client sends a request to create an order, the system processes that incoming message accordingly.

In contrast, sending a notification email is an action performed by the system to communicate information, rather than receiving a request. Logging out a user is also an action taken by the system based on a user-initiated event. Generating reports similarly involves the system producing information based on existing data rather than receiving input in the form of an incoming message. Therefore, creating an order distinctly aligns with the definition of an Incoming Message as it involves the system receiving a directive to take action on a new order.
