ConnectParticipant / Client / send_event




The application/vnd.amazonaws.connect.event.connection.acknowledged ContentType will no longer be supported starting December 31, 2024. This event has been migrated to the CreateParticipantConnection API using the ConnectParticipant field.

Sends an event. Message receipts are not supported when there are more than two active participants in the chat. Using the SendEvent API for message receipts when a supervisor is barged-in will result in a conflict exception.


ConnectionToken is used for invoking this API instead of ParticipantToken.

The Amazon Connect Participant Service APIs do not use Signature Version 4 authentication.
