See ‘aws help’ for descriptions of global parameters.


--data <value>
--connection-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]


--data (blob)

The data to be sent to the client specified by its connection id.

--connection-id (string)

The identifier of the connection that a specific client is using.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
