Available flags

Flag Purpose
read Whether the user has read the message. Messages start out unread (except for messages the user themself sent using a non-API client) and can later be marked as read.
starred Whether the user has starred this message.
collapsed Whether the user has collapsed this message.
mentioned Whether the current user was mentioned by this message, either directly or via a user group. Cannot be changed by the user directly, but can change if the message is edited to add/remove a mention of the current user.
stream_wildcard_mentioned Whether this message contained a channel wildcard mention (like @**all**). Cannot be changed by the user directly, but can change if the message is edited to add/remove a channel wildcard mention.

Changes: New in Zulip 8.0 (feature level 224).
topic_wildcard_mentioned Whether this message contained a topic wildcard mention (@**topic**). Cannot be changed by the user directly, but can change if the message is edited to add/remove a topic wildcard mention.

Changes: New in Zulip 8.0 (feature level 224).
has_alert_word Whether the message contains any of the current user's configured alert words. Cannot be changed by the user directly, but can change if the message is edited to add/remove one of the current user's alert words.
historical Is true for messages that the user did not receive at the time they were sent but later was added to the user's history (e.g. because they starred or reacted to a message sent to a public channel before they subscribed to that channel). Cannot be changed by the user directly.
wildcard_mentioned Whether this message contained either a channel wildcard mention (like @**all**) or a topic wildcard mention (@**topic**). Cannot be changed by the user directly, but can change if the message is edited to add/remove a channel and/or topic wildcard mention.

Changes: Deprecated in Zulip 8.0 (feature level 224), in favor of the stream_wildcard_mentioned and topic_wildcard_mentioned flags. The wildcard_mentioned flag exists for backwards compatibility with older clients and equals stream_wildcard_mentioned || topic_wildcard_mentioned. Clients supporting older server versions should treat this field as a previous name for the stream_wildcard_mentioned flag as topic wildcard mentions were not available prior to this feature level.

Response

Return values
