State Design Mode MSMQ Message Queue

A transaction management module has been developed recently. The transaction has multiple statuses, including transaction creation, transaction distribution, transaction acceptance, transaction processing, and transaction termination, in addition, the transaction can be processed differently based on the status. I have designed a class library based on the state design mode. The transaction management module adopts the B/S mode, A bit confused: the State of the transaction is changed, and how to automatically call the transaction method to make it run automatically is that the process of the transaction must go through the message queue, this transaction management module is similar to the current ticket system. If you have worked on such a system, give me some advice. Thank you.
