[ aws . connect ]



The StartOutboundVoiceContact operation initiates a contact flow to place an outbound call to a customer.

If you are using an IAM account, it must have permission to the connect:StartOutboundVoiceContact action.

There is a 60 second dialing timeout for this operation. If the call is not connected after 60 seconds, the call fails.

--destination-phone-number (string)

The phone number of the customer in E.164 format.

--contact-flow-id (string)

The identifier for the contact flow to connect the outbound call to.

To find the ContactFlowId , open the contact flow you want to use in the Amazon Connect contact flow editor. The ID for the contact flow is displayed in the address bar as part of the URL. For example, the contact flow ID is the set of characters at the end of the URL, after 'contact-flow/' such as 78ea8fd5-2659-4f2b-b528-699760ccfc1b .

--instance-id (string)

The identifier for your Amazon Connect instance. To find the ID of your instance, open the AWS console and select Amazon Connect. Select the alias of the instance in the Instance alias column. The instance ID is displayed in the Overview section of your instance settings. For example, the instance ID is the set of characters at the end of the instance ARN, after instance/, such as 10a4c4eb-f57e-4d4c-b602-bf39176ced07.

--client-token (string)

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. The token is valid for 7 days after creation. If a contact is already started, the contact ID is returned. If the contact is disconnected, a new contact is started.

--source-phone-number (string)

The phone number, in E.164 format, associated with your Amazon Connect instance to use for the outbound call.

--queue-id (string)

The queue to add the call to. If you specify a queue, the phone displayed for caller ID is the phone number specified in the queue. If you do not specify a queue, the queue used will be the queue defined in the contact flow.

To find the QueueId , open the queue you want to use in the Amazon Connect Queue editor. The ID for the queue is displayed in the address bar as part of the URL. For example, the queue ID is the set of characters at the end of the URL, after 'queue/' such as queue/aeg40574-2d01-51c3-73d6-bf8624d2168c .

--attributes (map)

Specify a custom key-value pair using an attribute map. The attributes are standard Amazon Connect attributes, and can be accessed in contact flows just like any other contact attributes.

There can be up to 32,768 UTF-8 bytes across all key-value pairs per contact. Attribute keys can include only alphanumeric, dash, and underscore characters.

For example, if you want play a greeting when the customer answers the call, you can pass the customer name in attributes similar to the following:

Shorthand Syntax:


JSON Syntax:

{"string": "string"

--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.

See 'aws help' for descriptions of global parameters.
