The Transaction Monitoring Event

You can expect to receive EventTransactionStatus once you have successfully subscribed to transaction monitoring. Information about your subscription request is also available from EventACK, EventError, and EventServerInfo. For descriptions of these general T-Library events and their transaction monitoring specifics, see EventACK, EventError, and EventServerInfo. For descriptions of event attributes generally, see Event Attributes.
