An event destination is a location (such as a CloudWatch Group, a Amazon Data Firehose stream, or an Amazon SNS topic) that SMS and voice events are sent to. To use event destinations, you first create the destination, and then associate it with a Configuration sets in AWS End User Messaging SMS. You can associate up to five event destinations with a single configuration set. When you send a message, your call to the API includes a reference to the configuration set.
Events or Delivery Receipts (DLR) generated
by carriers can take up to 72 hours to be received and should not be used to determine if
there is a delay in outbound message delivery. After 72 hours, if AWS End User Messaging SMS has not received a
final event from a carrier, the service will automatically return an UNKNOWN
messageStatus as we do not know what happened to that message.
Prerequisites
You need to have already created a configuration set to associate the event destinations with, see Configuration sets in AWS End User Messaging SMS.
