Parameters
type string required
Example: "direct"
The type of scheduled message to be sent. "direct" for a direct
message and "stream" or "channel" for a channel message.
Note that, while "private" is supported for scheduling direct
messages, clients are encouraged to use to the modern convention of
"direct" to indicate this message type, because support for
"private" may eventually be removed.
Changes: In Zulip 9.0 (feature level 248), "channel" was added as
an additional value for this parameter to indicate the type of a channel
message.
Must be one of: "direct", "channel", "stream", "private".

The scheduled message's tentative target audience.
For channel messages, the integer ID of the channel.
For direct messages, a list containing integer user IDs.
content string required
Example: "Hello"
The content of the message.
Clients should use the max_message_length returned by the
POST /register endpoint to determine
the maximum message size.
topic string optional
Example: "Castle"
The topic of the message. Only required for channel messages
("type": "stream" or "type": "channel"), ignored otherwise.
Clients should use the max_topic_length returned by the
POST /register endpoint to determine
the maximum topic length.
scheduled_delivery_timestamp integer required
Example: 3165826990
The UNIX timestamp for when the message will be sent,
in UTC seconds.
read_by_sender boolean optional
Example: true
