Asynchronous and synchronous events

📝 Note: AppDirect supports both types of event and recommends that you use asynchronous (delayed response) events.

Asynchronous events

AppDirect supports and recommends that you use asynchronous events when a business process requires a delayed response. AppDirect listens for the delayed response to arrive. See Asynchronous subscription events.

Synchronous events

AppDirect supports but does not recommend that you use synchronous events. Use asynchronous events for your integrations. If you use synchronous events the maximum amount of time allowed for a synchronous event response is 5 seconds.

The SUBSCRIPTION_NOTICE event is the only subscription event that does not involve a response so it is only supported as a synchronous event.
