Message and event destinations in AWS End User Messaging Social

An event destination is an Amazon SNS topic that WhatsApp events are sent to. When you turn on event publishing to an Amazon SNS topic, all of your send and receive events are sent to the Amazon SNS topic. Use events to monitor, track, and analyze the status of outbound messages and incoming customer communications.

Each WhatsApp Business Account (WABA) can have one event destination. All events from all resources associated to the WhatsApp Business Account are logged to that event destination. For example, you could have a WhatsApp Business Account with three phone numbers associated to it and all events from those phone numbers are logged to the one event destination.
