[ aws . connect ]



The start-outbound-voice-contact operation initiates a contact flow to place an outbound call to a customer.

There is a throttling limit placed on usage of the API that includes a RateLimit of 2 per second, and a BurstLimit of 5 per second.

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

[--source-phone-number <value>]

--destination-phone-number (string)

The phone number, in E.164 format, of the customer to call with the outbound contact.

--contact-flow-id (string)

The identifier for the contact flow to execute for the outbound call. This is a GUID value only. Amazon Resource Name (ARN) values are not supported.

To find the contact-flow-id , open the contact flow to use in the Amazon Connect contact flow designer. The ID for the contact flow is displayed in the address bar as part of the URL. For example, an address displayed when you open a contact flow is similar to the following:*b0b8f2dd-ed1b-4c44-af36-ce189a178181* `` . At the end of the URL, you see ``contact-flow/b0b8f2dd-ed1b-4c44-af36-ce189a178181 . The ContactFlowID for this contact flow is `` b0b8f2dd-ed1b-4c44-af36-ce189a178181 `` . Make sure to include only the GUID after the "contact-flow/" in your requests.

--instance-id (string)

The identifier for your Amazon Connect instance. To find the instance-id value for your Amazon Connect instance, open the Amazon Connect console . Select the instance alias of the instance and view the instance ID in the Overview section. 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 to place the outbound call.

--queue-id (string)

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

To find the queue-id , open the queue 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 value is the set of characters at the end of the URL, after "queue/", such as 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. Attribute keys can include only alphanumeric, dash, and underscore characters.

For example, to 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.

--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.


ContactId -> (string)

The unique identifier of this contact within your Amazon Connect instance.
