-- 'messageId', 'message_messageId' - The ID you want to assign to the message. Each @messageId@ must be

-- 'payload', 'message_payload' - The payload of the message. This can be a JSON string or a

-- decode it by means of a pipeline activity.--
-- -- /Note:/ This 'Lens' automatically encodes and decodes Base64 data.
-- -- The underlying isomorphism will encode to Base64 representation during
-- -- serialisation, and decode from Base64 representation during deserialisation.
-- -- This 'Lens' accepts and returns only raw unencoded data.
