messages

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.
