--room-filters (list)

The filters to use to send an announcement to a specified list of rooms. The supported filter keys are RoomName, ProfileName, RoomArn, and ProfileArn. To send to all rooms, specify an empty RoomFilters list.


A filter name and value pair that is used to return a more specific list of results. Filters can be used to match a set of resources by various criteria.

Key -> (string)

The key of a filter.

Values -> (list)

The values of a filter.


Shorthand Syntax:

Key=string,Values=string,string ...

JSON Syntax:

    "Key": "string",
    "Values": ["string", ...]

--content (structure)

The announcement content. This can contain only one of the three possible announcement types (text, SSML or audio).

TextList -> (list)

The list of text messages.


The text message.

Locale -> (string)

The locale of the text message. Currently, en-US is supported.

Value -> (string)

The audio message. There is a 1 MB limit on the audio file input and the only supported format is MP3. To convert your MP3 audio files to an Alexa-friendly,

required codec version (MPEG version 2) and bit rate (48 kbps), you might use converter software. One option for this is a command-line tool, FFmpeg. For more information, see FFmpeg . The following command converts the provided <input-file> to an MP3 file that is played in the announcement:

ffmpeg -i <input-file> -ac 2 -codec:a libmp3lame -b:a 48k -ar 16000 <output-file.mp3>

Locale -> (string)

The locale of the audio message. Currently, en-US is supported.

Location -> (string)

The location of the audio file. Currently, S3 URLs are supported. Only S3 locations comprised of safe characters are valid. For more information, see Safe Characters .

--time-to-live-in-seconds (integer)

The time to live for an announcement. Default is 300. If delivery doesn't occur within this time, the announcement is not delivered.

--client-request-token (string)

The unique, user-specified identifier for the request that ensures idempotency.

--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.
