API changelog

This page documents changes to the Zulip Server API over time. See also the Zulip release lifecycle for background on why this API changelog is important, and the Zulip server changelog.

The API feature levels system used in this changelog is designed to make it possible to write API clients, such as the Zulip mobile and terminal apps, that work with a wide range of Zulip server versions. Every change to the Zulip API is recorded briefly here and with full details in Changes entries in the API documentation for the modified endpoint(s).

When using an API endpoint whose behavior has changed, Zulip API clients should check the zulip_feature_level field, present in the GET /server_settings and POST /register responses, to determine the API format used by the Zulip server that they are interacting with.

This can then be used as the value in the aforementioned parameter to avoid re-fetching of already known data when polling the endpoint next time. Additionally, the client specifying the last_update_id implies it uses the modern API format, so slim_presence=true will be assumed by the server.
POST /register: The response now also includes a presence_last_update_id field, with the same meaning as described above for /users/me/presence. In the same way, the retrieved value can be passed when querying /users/me/presence to avoid re-fetching of already known data.

Feature level 259

POST /register, GET /events: For the onboarding_steps event type, an array of onboarding steps to be displayed to clients is sent. Onboarding step now has one-time notices as the only valid type. Prior to this, both hotspots and one-time notices were valid types of onboarding steps. There is no compatibility support, as we expect that only official Zulip clients will interact with this data. Currently, no client other than the Zulip web app uses this.

Feature level 256

POST /streams/{stream_id}/delete_topic, GET /events: When messages are deleted, a stream op: update event with an updated value for first_message_id may now be sent to clients.

Feature level 255

Also, added a type field to the objects returned in the renamed onboarding_steps array to distinguish between the two types of onboarding steps.
POST /users/me/onboarding_steps: Added a new endpoint, which deprecates the /users/me/hotspots endpoint, in order to support displaying both one-time notices (which highlight new features for existing users) and hotspots (which are used in new user tutorials). This endpoint marks both types of onboarding steps, i.e. hotspot and one_time_notice, as read by the user. There is no compatibility support for /users/me/hotspots as no client other than the Zulip web app used the endpoint prior to these changes.

Feature level 232

Feature level 228

GET /events: realm_user events with op: "update" are now only sent to users who can access the modified user.

Feature level 224

GET /events, GET /messages, GET /messages/{message_id}: Of the available message flags that a user may have for a message, the wildcard_mentioned flag was deprecated in favor of the stream_wildcard_mentioned and topic_wildcard_mentioned flags, but it is still available for backwards compatibility.

Feature level 223

POST /users/me/apns_device_token: The appid parameter is now required. Previously it defaulted to the server setting ZULIP_IOS_APP_ID, defaulting to "org.zulip.Zulip".
POST /remotes/server/register: The ios_app_id parameter is now required when kind is 1, i.e. when registering an APNs token. Previously it was ignored, and the push bouncer effectively assumed its value was the server setting APNS_TOPIC, defaulting to "org.zulip.Zulip".

Feature level 222

GET /events: When a user is deactivated or reactivated, the server uses realm_user events with op: "update" updating the is_active field, instead of realm_user events with op: "remove" and op: "add", respectively.

Feature level 220

GET /events: Stream creation events for web-public streams are now sent to all guest users in the organization as well.
GET /events: The subscription events for op: "peer_add" and op: "peer_remove" are now sent to subscribed guest users for public streams and to all the guest users for web-public streams; previously, they incorrectly only received these for private streams.

POST /typing: Stopped supporting private as a valid value for the type parameter.
POST /typing: Stopped using the to parameter for the "stream" type. Previously, in the case of the "stream" type, it accepted a single-element list containing the ID of the stream.

Feature level 212

GET /events, POST /register, PATCH /realm: Added the jitsi_server_url field to the realm object, allowing organizations to set a custom Jitsi Meet server. Previously, this was only available as a server-level configuration.

Feature level 211

POST /streams/{stream_id}/delete_topic, POST /mark_all_as_read: Added a complete boolean field in the success response to indicate whether all or only some of the targeted messages were processed. This replaces the use of "result": "partially_completed" (introduced in feature levels 154 and 153), so that these endpoints now send a result string of either "success" or "error", like the rest of the Zulip API.

Feature level 210

POST /register, PATCH /settings, PATCH /realm/user_settings_defaults: Added new web_stream_unreads_count_display_policy display setting, which controls in which streams (all/unmuted/none) unread messages count shows up in left sidebar.

Feature level 209

PATCH /realm, POST /register, GET /events: Added create_multiuse_invite_group realm setting, which is the ID of the user group whose members can create reusable invitation links to an organization. Previously, only admin users could create these links.
POST /invites/multiuse: Non-admin users can now use this endpoint to create reusable invitation links. Previously, this endpoint was restricted to admin users only.
GET /invites: Endpoint response for non-admin users now includes both email invitations and reusable invitation links that they have created. Previously, non-admin users could only create email invitations, and therefore the response did not include reusable invitation links for these users.
DELETE /invites/multiuse/{invite_id}: Non-admin users can now revoke reusable invitation links they have created. Previously, only admin users could create and revoke reusable invitation links.
GET /events: When the set of invitations in an organization changes, an invites_changed event is now sent to the creator of the changed invitation, as well as all admin users. Previously, this event was only sent to admin users.

Feature level 208

POST /users/me/subscriptions, DELETE /users/me/subscriptions: These endpoints now return an HTTP status code of 400 with code: "BAD_REQUEST" in the error response when a user specified in the principals parameter is deactivated or does not exist.

Feature level 207

Feature level 195

GET /events, POST /register: The default_code_block_language realm setting is now consistently an empty string when no default pygments language code is set. Previously, the server had a bug that meant it might represent no default for this realm setting as either null or an empty string. Clients supporting older server versions should treat either value (null or "") as no default being set.

Feature level 194

GET /messages, GET /messages/matches_narrow, POST /messages/flags/narrow, POST /register: For search/narrow filters with the id operator, added support for encoding the message ID operand as either a string or an integer. Previously, only string encoding was supported.

Changes in Zulip 7.0

Feature level 185

No changes; feature level used for Zulip 7.0 release.

Feature level 184

PATCH /scheduled_messages/<int:scheduled_message_id>: Added new endpoint for editing an existing scheduled message.
POST /scheduled_messages: Removed optional scheduled_message_id parameter, which had been a previous way for clients to support editing an existing scheduled message.

Feature level 183

POST /register: Removed the realm_community_topic_editing_limit_seconds property, which was no longer in use. The time limit for editing topics is controlled by the realm setting move_messages_within_stream_limit_seconds, see feature level 162.
GET /events: Removed the community_topic_editing_limit_seconds property from realm update_dict event documentation, because it was never returned as a changed property in this event and was only ever returned in the POST /register response.

Feature level 182

POST /export/realm: This endpoint now returns the ID of the data export object created by the request.

Feature level 181

GET /scheduled_messages, GET /events, POST /register: Added failed boolean field to scheduled message objects to indicate if the server tried to send the scheduled message and was unsuccessful. Clients that support unscheduling and editing scheduled messages should use this field to indicate to the user when a scheduled message failed to send at the appointed time.

Feature level 180

POST /invites: Added support for invitations specifying the empty list as the user's initial stream subscriptions. Previously, this returned an error. This change was also backported to Zulip 6.2, and is available at feature levels 157-158 as well.

Feature level 179

POST /scheduled_messages: Added new endpoint to create and edit scheduled messages.
GET /events: Added scheduled_messages events sent to clients when a user creates, edits or deletes scheduled messages.

Feature level 178

POST /users/me/presence, GET /users/<user_id_or_email>/presence, GET /realm/presence, POST /register, GET /events: The server no longer stores which client submitted presence data, and presence responses from the server will always contain the "aggregated" and "website" keys.

Feature level 177

GET /messages, GET /messages/matches_narrow, POST /messages/flags/narrow, POST /register: Added support for three search/narrow filters related to direct messages: is:dm, dm and dm-including. The dm operator replaces and deprecates the pm-with operator. The is:dm filter replaces and deprecates the is:private filter. The dm-including operator replaces and deprecates the group-pm-with operator. Because existing Zulip messages may have links with these legacy filters, they are still supported for backwards-compatibility.

Feature level 176

POST /realm/filters, PATCH /realm/filters/<int:filter_id>: The url_format_string parameter is replaced by url_template. Linkifiers now only accept RFC 6570 compliant URL templates. The old URL format strings are no longer supported.
GET /events, POST /register: The url_format_string key in realm_linkifiers objects is replaced by url_template. For backwards-compatibility, clients that do not support the linkifier_url_template client capability will receive an empty realm_linkifiers array in the /register response and not receive realm_linkifiers events. Unconditionally, the deprecated realm_filters event type returns an empty array in the /register response and these events are no longer sent to clients.

Feature level 175

POST /register, PATCH /settings, PATCH /realm/user_settings_defaults: Added new user setting web_mark_read_on_scroll_policy. Clients may use this to determine the user's preference on whether to mark messages as read or not when scrolling through their message feed.

Feature level 174

POST /typing, POST /messages: Added "direct" as the preferred way to indicate a direct message for the type parameter, deprecating the original "private". While "private" is still supported for direct messages, clients are encouraged to use the modern convention with servers that support it, because support for "private" may eventually be removed.

Feature level 173

GET /scheduled_messages, DELETE /scheduled_messages/<int:scheduled_message_id>: Added new endpoints to fetch and delete scheduled messages.

Feature level 172

PATCH /messages/{message_id}: Topic editing restrictions now apply to stream messages without a topic.
PATCH /messages/{message_id}: When users, other than organization administrators and moderators, use "propagate_mode": "change_all" to move messages that have passed the organization's time limit for updating a message's topic and/or stream, this endpoint now returns an error response ("code": "MOVE_MESSAGES_TIME_LIMIT_EXCEEDED").

Feature level 171

POST /fetch_api_key, POST /dev_fetch_api_key: The return values for these endpoints now include the unique ID of the user who owns the API key.

Feature level 170

POST /user_topics: Added a new endpoint to update a user's personal preferences for a topic, which deprecates the PATCH /users/me/subscriptions/muted_topics endpoint. The deprecated endpoint is maintained for backwards-compatibility but may be removed in a future release.

Feature level 168

POST /register, PATCH /settings, PATCH /realm/user_settings_defaults: Replaced the boolean user setting realm_name_in_notifications with an integer realm_name_in_email_notifications_policy.

Feature level 167

All REST API endpoints: Implemented ignored_parameters_unsupported as a possible return value in the JSON success response for all endpoints. This value is a array of any parameters that were sent in the request by the client that are not supported by the endpoint. Previously, unsupported parameters were silently ignored, except in the subset of endpoints which already supported this return value; see feature levels 111, 96 and 78.

Feature level 166

POST /messages: Eliminated the undocumented realm_str parameter. This parameter was already redundant due to it needing to match the realm of the user making the request, otherwise returning an authorization error. With this, the parameter is removed, meaning that if provided in the API request, it will be ignored.

Feature level 165

PATCH /user_groups/{user_group_id}: The name and description parameters are now optional.

Feature level 164

POST /register: Added the server_presence_ping_interval_seconds and server_presence_offline_threshold_seconds fields for clients to use when implementing the presence system.

Feature level 163

GET /users, GET /users/{user_id}, GET /users/{email}, GET /users/me, GET /events: The delivery_email field is always present in user objects, including the case when a user's email_address_visibility is set to everyone. The value will be null if the requester does not have access to the user's real email. For bot users, the delivery_email field is always set to the bot user's real email.
GET /events: Event for updating a user's delivery_email is now sent to all users who have access to it, and is also sent when a user's email_address_visibility setting changes.
GET /events, POST /register GET /users, GET /users/{user_id}, GET /users/{email}, GET /users/me, GET /messages, GET /messages/{message_id}: Whether the avatar_url field in message and user objects returned by these endpoints can be null now depends on if the current user has access to the other user's real email address based on the other user's email_address_visibility policy.
POST /register, PATCH /settings, PATCH /realm/user_settings_defaults: Added user setting email_address_visibility, to replace the realm setting email_address_visibility.

PATCH /messages/{message_id}: For users other than administrators and moderators, the time limit for editing topics is now controlled via the realm setting move_messages_within_stream_limit_seconds and the time limit for moving messages between streams is now controlled by the realm setting move_messages_between_streams_limit_seconds.

Feature level 161

POST /users/me/subscriptions, PATCH /streams/{stream_id}: Added can_remove_subscribers_group_id parameter to support setting and changing the user group whose members can remove other subscribers from the specified stream.
DELETE /users/me/subscriptions: Expanded the situations where users can use this endpoint to unsubscribe other users from a stream to include the case where the current user has access to the stream and is a member of the user group specified by the can_remove_subscribers_group_id for the stream.

Feature level 160

POST /api/v1/jwt/fetch_api_key: Added new endpoint to fetch API keys using JSON Web Token (JWT) authentication.
accounts/login/jwt/: Adjusted format of requests to undocumented, optional endpoint for JWT authentication log in support.

Feature level 159

PATCH /realm, POST /register, GET /events: Nobody added as an option for the realm settings edit_topic_policy and move_messages_between_streams_policy.
PATCH /messages/{message_id}: Permission to edit the stream and/or topic of messages no longer depends on the realm setting allow_message_editing.
PATCH /messages/{message_id}: The user who sent the message can no longer edit the message's topic indefinitely.

Feature level 158 is reserved for future use in 6.x maintenance releases.

Changes in Zulip 6.2

Feature level 157

POST /invites: Added support for invitations specifying the empty list as the user's initial stream subscriptions. Previously, this returned an error. This change was backported from the Zulip 7.0 branch, and thus is available at feature levels 157-158 and 180+.

Feature level 154

POST /streams/{stream_id}/delete_topic: When the process of deleting messages times out, but successfully deletes some messages in the topic (see feature level 147 for when this endpoint started deleting messages in batches), a success response with "result": "partially_completed" will now be returned by the server, analogically to the POST /mark_all_as_read endpoint (see feature level 153 entry below).

Feature level 153

POST /mark_all_as_read: Messages are now marked as read in batches, so that progress will be made even if the request times out because of an extremely large number of unread messages to process. Upon timeout, a success response with "result": "partially_completed" will be returned by the server.

Feature level 152

PATCH /messages/{message_id}: The default value for send_notification_to_old_thread was changed from true to false. When moving a topic within a stream, the send_notification_to_old_thread and send_notification_to_new_thread parameters are now respected, and by default a notification is sent to the new thread.

Feature level 151

POST /register, GET /events, POST /realm/profile_fields, GET /realm/profile_fields: Added pronouns custom profile field type.

Feature level 150

GET /events: Separate events are now sent on changing allow_message_editing, message_content_edit_limit_seconds and edit_topic_policy settings, whereas previously one event was sent including all of these setting values irrespective of which of them were actually changed.
PATCH /realm: Only changed settings are included in the response data now when changing allow_message_editing, edit_topic_policy and message_content_edit_limit_seconds settings, instead of including all the fields even if one of these settings was changed.

Feature level 119

POST /register: Added other_user_id field to the pms objects in the unread_msgs data set, deprecating the less clearly named sender_id field. This change was motivated by the possibility that a one-on-one direct message sent by the current user to another user could be marked as unread. The sender_id field is still present for backwards compatibility with older server versions.

Feature level 118

GET /messages, GET /events: Improved the format of the edit_history object within message objects. Entries for stream edits now include a both a prev_stream and stream field to indicate the previous and current stream IDs. Prior to this feature level, only the prev_stream field was present.
