[ aws . connect ]



Initiates a contact 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 need to 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 two situations:

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

For more information about how chat works, see Chat in the Amazon Connect Administrator Guide .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
