StartChatContact

Initiates a flow to start a new chat for the customer. Response of this API provides a token required to obtain credentials from the CreateParticipantConnection API in the Amazon Connect Participant Service.

When a new chat contact is successfully created, clients must subscribe to the participant’s connection for the created chat within 5 minutes. This is achieved by invoking CreateParticipantConnection with WEBSOCKET and CONNECTION_CREDENTIALS.

A 429 error occurs in the following situations:

API rate limit is exceeded. API TPS throttling returns a TooManyRequests exception.
The quota for concurrent active chats is exceeded. Active chat throttling returns a LimitExceededException.

If you use the ChatDurationInMinutes parameter and receive a 400 error, your account may not support the ability to configure custom chat durations. For more information, contact AWS Support.

For more information about chat, see the following topics in the Amazon Connect Administrator Guide:
