PublishRequest.Message Property

The message you want to send to the topic. If you want to send the same message to all transport protocols, include the text of the message as a String value. If you want to send different messages for each transport protocol, set the value of the MessageStructure parameter to json and use a JSON object for the Message parameter. See the Examples section for the format of the JSON object. Constraints: Messages must be UTF-8 encoded strings at most 256 KB in size (262144 bytes, not 262144 characters). JSON-specific constraints:

• Keys in the JSON object that correspond to supported transport protocols must have simple JSON string values.
• The values will be parsed (unescaped) before they are used in outgoing messages.
• Outbound notifications are JSON encoded (meaning that the characters will be reescaped for sending).
• Values have a minimum length of 0 (the empty string, "", is allowed).
• Values have a maximum length bounded by the overall message size (so, including multiple protocols may limit message sizes).
• Non-string values will cause the key to be ignored.
• Keys that do not correspond to supported transport protocols are ignored.
• Duplicate keys are not allowed.
• Failure to parse or validate any key or value in the message will cause the Publish call to return an error (no partial delivery).
