The UpdateInfo( ) or UpdateInfo2( ) API calls a notification callback function to execute the notification activity's post-notification function (if it has one) in QUESTION mode. As an example, the post-notification function may verify that the request is directed to a role that has appropriate authority to view the notification. If it doesn't, the post-notification function may return an error and prevent the request for more information from being sent. See: Post-notification Functions.

If no error is returned, the API then sends the request for more information to the designated role. Note that a request for information is also recorded in the comments of the notification.

If the recipient of a request for more information responds with answering information, the Notification Details web page calls the Notification System's UpdateInfo( ) API if the responder is logged in individually or the UpdateInfoGuest( ) API if the responder is logged in as the GUEST user, or a notification mailer calls the Notification System's UpdateInfo2( ) API.

The UpdateInfo( ), UpdateInfoGuest( ), or UpdateInfo2( ) API calls a notification callback function to execute the notification activity's post-notification function (if it has one) in ANSWER mode. As an example, the post-notification function may validate the answering information. If such validation fails, the post-notification function may return an error and prevent the answer from being sent. See: Post-notification Functions.

If no error is returned, the API then sends the answering information back to the recipient role of the original notification. Note that an answer to a request for information is also recorded in the comments of the notification.
