Parameters

Response

Return values

• id: integer

  The unique ID assigned to the sent message.

• automatic_new_visibility_policy: integer

  If the message's sender had configured their visibility policy settings to potentially automatically follow or unmute topics when sending messages, and one of these policies did in fact change the user's visibility policy for the topic where this message was sent, the new value for that user's visibility policy for the recipient topic.

  Only present if the sender's visibility was in fact changed.

  The value can be either unmuted or followed.

  Clients will also be notified about the change in policy via a user_topic event as usual. This field is intended to be used by clients to explicitly inform the user when a topic's visibility policy was changed automatically due to sending a message.

  For example, the Zulip web application uses this field to decide whether to display a warning or notice suggesting to unmute the topic after sending a message to a muted channel. Such a notice would be confusing in the event that the act of sending the message had already resulted in the user automatically unmuting or following the topic in question.

  Changes: New in Zulip 8.0 (feature level 218).

Example response(s)

Changes: As of Zulip 7.0 (feature level 167), if any parameters sent in the request are not supported by this endpoint, a successful JSON response will include an ignored_parameters_unsupported array.

A typical successful JSON response may look like:

{
    "automatic_new_visibility_policy": 2,
    "id": 42,
    "msg": "",
    "result": "success"
}

A typical failed JSON response for when a channel message is sent to a channel that does not exist:

{
    "code": "STREAM_DOES_NOT_EXIST",
    "msg": "Channel 'nonexistent' does not exist",
    "result": "error",
    "stream": "nonexistent"
}

A typical failed JSON response for when a direct message is sent to a user that does not exist:

{
    "code": "BAD_REQUEST",
    "msg": "Invalid email 'eeshan@zulip.com'",
    "result": "error"
}

An example JSON error response for when the message was rejected because of the organization's wildcard_mention_policy and large number of subscribers to the channel.

Changes: New in Zulip 8.0 (feature level 229). Previously, this error returned the "BAD_REQUEST" code.

{
    "code": "STREAM_WILDCARD_MENTION_NOT_ALLOWED",
    "msg": "You do not have permission to use channel wildcard mentions in this channel.",
    "result": "error"
}

An example JSON error response for when the message was rejected because the message contains a topic wildcard mention, but the user doesn't have permission to use such a mention in this topic due to the wildcard_mention_policy (and large number of participants in this specific topic).

Changes: New in Zulip 8.0 (feature level 229). Previously, wildcard_mention_policy was not enforced for topic mentions.

{
    "code": "TOPIC_WILDCARD_MENTION_NOT_ALLOWED",
    "msg": "You do not have permission to use topic wildcard mentions in this topic.",
    "result": "error"
}
