The TransactionManager is a class that makes it easy to always grab the next transaction ID. It can be used in a singleton pattern. You may manage transaction IDs yourself, but the API uses this class, and it will then be up to your application to not create IDs that conflict with the APIs requests. This may become particularly tricky if you also use the API's SubscriptionManager. If you send requests with your own transaction IDs and Photoshop responds with those IDs, it's possible you could trigger the SubscriptionManager for any active subscriptions, leading to undetermined behavior (probably parsing errors or SubscriptionEvents with confusing data).
