Which of the following is a characteristic of outbound messaging?

Outbound messaging in Salesforce is a feature that enables communication from Salesforce to external systems. One key characteristic is that outbound messages can include enterprise or partner URLs, as well as a session ID token. This allows for proper authentication and routing of messages to the correct endpoint, facilitating seamless integration with external systems.

The inclusion of the session ID is particularly important as it provides a way for the external system to validate the request and ensure that it is receiving messages from an authenticated Salesforce instance. This enhances security and ensures data integrity during the communication process.

Outbound messaging operates asynchronously, meaning that messages are sent without the need for the user's presence, and they do not require immediate acknowledgment. Therefore, the messaging process is independent of user actions. This characteristic makes it suitable for workflows and automated processes, allowing for greater efficiency in system integrations.
