Request Syntax

response = client.batch_put_message(
    channelName='string',
    messages=[
        {
            'messageId': 'string',
            'payload': b'bytes'
        },
    ]
)

Parameters

• channelName (string) --

  [REQUIRED]

  The name of the channel where the messages are sent.

• messages (list) --

  [REQUIRED]

  The list of messages to be sent. Each message has the format: { "messageId": "string", "payload": "string"}.

  The field names of message payloads (data) that you send to IoT Analytics:

  • Must contain only alphanumeric characters and undescores (_). No other special characters are allowed.
  • Must begin with an alphabetic character or single underscore (_).
  • Cannot contain hyphens (-).
  • In regular expression terms: "^[A-Za-z_]([A-Za-z0-9]*|[A-Za-z0-9][A-Za-z0-9_]*)$".
  • Cannot be more than 255 characters.
  • Are case insensitive. (Fields named foo and FOO in the same payload are considered duplicates.)

  For example, {"temp_01": 29} or {"_temp_01": 29} are valid, but {"temp-01": 29}, {"01_temp": 29} or {"__temp_01": 29} are invalid in message payloads.

  • (dict) --

    Information about a message.

    • messageId (string) -- [REQUIRED]

      The ID you want to assign to the message. Each messageId must be unique within each batch sent.

    • payload (bytes) -- [REQUIRED]

      The payload of the message. This can be a JSON string or a base64-encoded string representing binary data, in which case you must decode it by means of a pipeline activity.
