Sends a message to a particular channel that the member is a part of.


The x-amz-chime-bearer request header is mandatory. Use the AppInstanceUserArn of the user that makes the API call as the value in the header.

Also, STANDARD messages can contain 4KB of data and the 1KB of metadata. CONTROL messages can contain 30 bytes of data and no metadata.

--channel-arn (string)

The ARN of the channel.

--content (string)

The content of the message.

--type (string)

The type of message, STANDARD or CONTROL .

Possible values:



--persistence (string)

Boolean that controls whether the message is persisted on the back end. Required.

The Idempotency token for each client request.

--chime-bearer (string)

The AppInstanceUserArn of the user that makes the API call.

--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.

See ‘aws help’ for descriptions of global parameters.
