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.
Changes in Zulip 10.0
Feature level 297
Feature level 296:
Feature level 295
GET /export/realm/consents
: Added
a new endpoint to fetch the consents of users for their private data
exports.
/api/v1/tus
is an endpoint implementing the tus
protocol for resumable uploads.
Clients which send authenticated credentials (either via browser-based
cookies, or API key via Authorization
header) may use this endpoint to
create uploads, similar to POST /user_uploads
.
Feature level 294
POST /register
: Clients that do not
support the include_deactivated_groups
client capability
do not receive deactivated user groups in the response.
GET /events
: Clients that do not support the
include_deactivated_groups
client capability
receive remove
event on user group deactivation instead of update
event.
GET /events
: Clients that do not support the
include_deactivated_groups
client capability
do not receive update
event when name of a deactivated user group
is updated.
GET /user_groups
: Renamed allow_deactivated
parameter to include_deactivated_groups
.
DELETE /user_groups/{user_group_id}
: Removed support for user group
deletion as we now support deactivating user groups.

whether to let administrators export their private data.
Feature level 292
Feature level 291
PATCH /realm
, GET /events
,
POST /register

Added can_delete_own_message_group
realm setting which is a
group-setting value describing the set of users
with permission to delete the messages that they have sent in the organization.
PATCH /realm
, GET /events
: Removed
delete_own_message_policy
property, as the permission to delete own messages
is now controlled by can_delete_own_message_group
setting.
Feature level 290
Feature level 289
Feature level 288
POST /register
:
A new presence_history_limit_days
parameter can be given, instructing
the server to only fetch presence data more recent than the given
number of days ago.
POST /users/me/presence
:
A new history_limit_days
parameter can be given, with the
same meaning as in the presence_history_limit_days
parameter of
POST /register
above.
Feature level 287
- Markdown message
formatting: Added
data-original-dimensions
attributes to placeholder images
(image-loading-placeholder
), containing the dimensions of the
original image. This change was also backported to the Zulip 9.x
series, at feature level 278.
Feature level 286

field to
the response, which is closer to the original filename than the
basename of the url
field in the response.

property, as the permission to create
web-public channels is now controlled by can_create_web_public_channel_group
setting.
POST /register
: realm_create_web_public_stream_policy
field is deprecated, having been replaced by can_create_web_public_channel_group
.
Notably, this backwards-compatible realm_create_web_public_stream_policy

permission setting.
Feature levels 278-279 are reserved for future use in 9.x maintenance
releases.

group-setting value describing the
set of users of which at least one member must be included as sender
or recipient in all personal and group direct messages.
Removed private_message_policy

direct messages is now controlled by direct_message_initiator_group
and direct_message_permission_group
settings.
Feature level 269
Feature level 268

GET /invites
,POST /invites

via this invitation.
Feature level 266
PATCH /realm
, POST /register
,

: Added can_create_private_channel_group
realm setting, which is a group-setting value
describing the set of users with permission to create private channels.
PATCH /realm
, GET /events
: Removed
create_private_stream_policy
property, as the permission to create private
channels is now controlled by can_create_private_channel_group
setting.
POST /register
: realm_create_private_stream_policy

.
Notably, this backwards-compatible realm_create_private_stream_policy

now contains the superset of the true value that best approximates the actual
permission setting.
Feature level 265
Feature level 264
PATCH /realm
, POST /register

realm setting, which is a group-setting value
describing the set of users with permission to create channels.

field is deprecated, having been replaced by can_create_public_channel_group
.
Notably, this backwards-compatible realm_create_public_stream_policy
value
now contains the superset of the true value that best approximates the actual
permission setting.
Feature level 263
-
POST /users/me/presence
:
A new last_update_id
parameter can be given, instructing
the server to only fetch presence data with last_update_id
greater than the value provided. The server also provides
a presence_last_update_id
field in the response, which
tells the client the greatest last_update_id
of the fetched
presence data. 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 262
Feature level 261
POST /invites
,
POST /invites/multiuse
: Added
include_realm_default_subscriptions
parameter to indicate whether
the newly created user will be automatically subscribed to default
channels in the
organization. Previously, the default channel IDs needed to be included
in the stream_ids
parameter. This also allows a newly created user
to be automatically subscribed to the default channels in an
organization when the user creating the invitation does not generally
have permission to subscribe other users to
channels.
Feature level 260
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 258
Feature level 257
POST /register
,
POST /server_settings
, PATCH /realm
:
realm_uri
was renamed to realm_url
, but remains available as a
deprecated alias for backwards-compatibility.
- Mobile push notification payloads, similarly, have a new
realm_url
,
replacing realm_uri
, which remains available as a deprecated alias
for backwards-compatibility.
Feature level 256
Feature level 255
- "Stream" was renamed to "Channel" across strings in the Zulip API
and UI. Clients supporting a range of server versions are encouraged
to use different strings based on the server's API feature level for
consistency. Note that feature level marks the strings transition
only: Actual API changes related to this transition have their own
API changelog entries.
Feature level 254
Feature level 253
Feature level 252
PATCH /realm/profile_fields/{field_id}
: name
, hint
, display_in_profile_summary
,
required
and field_data
fields are now optional during an update. Previously we
required the clients to populate the fields in the PATCH request even if there was
no change to those fields' values.
Feature level 251
POST /register
: Fixed realm_upload_quota_mib
value to actually be in MiB. Until now the value was in bytes.
Feature level 250
Feature level 249
Feature level 248
Feature level 247
Feature level 246
Feature level 245
Feature level 244
Feature level 243
POST /register
, GET
/events
: Changed the format of
realm_authentication_methods
and authentication_methods
,
respectively, to use a dictionary rather than a boolean as the value
for each authentication method. The new dictionaries are more
extensively and contain fields indicating whether the backend is
unavailable to the current realm due to Zulip Cloud plan
restrictions or any other reason.
Feature level 242
POST /register
, POST /events
,
PATCH /realm
: Added zulip_update_announcements_stream_id
realm setting,
which is the ID of the of the stream to which automated messages announcing
new features or other end-user updates about the Zulip software are sent.
Feature level 241
POST /register
, POST /events
,
PATCH /realm
: Renamed the realm settings notifications_stream
and
signup_notifications_stream
to new_stream_announcements_stream
and
signup_announcements_stream
, respectively.
Feature level 240
GET /events
: The restart
event no longer contains an
optional immediate
flag.
GET /events
: A new web_reload_client
event has been
added; it is used to signal to website-based clients that they should reload
their code. This was previously implied by the restart
event.

releases.
Changes in Zulip 8.0
Feature level 237
No changes; feature level used for Zulip 8.0 release.
Feature level 236
POST /messages
, POST
/scheduled_messages
: The new
read_by_sender
parameter lets the client override the heuristic
that determines whether the new message will be initially marked
read by its sender.
Feature level 235
Feature level 234
- Mobile push notifications now include a
realm_name
field.
POST /mobile_push/test_notification
now sends
a test notification with test
rather than test-by-device-token
in the event
field.
Feature level 233
-
POST /register
, GET /events
:
Renamed the hotspots
event type and the related hotspots
object array
to onboarding_steps
. These are sent to clients if there are onboarding
steps to display to the user. Onboarding steps now include
both hotspots and one-time notices. Prior to this, hotspots were the only
type of onboarding step. 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
-
POST /register
: Added a new
user_list_incomplete
client
capability
controlling whether realm_users
contains "Unknown user"
placeholder objects for users that the current user cannot access
due to a can_access_all_users_group
policy.
-
GET /events
: The new user_list_incomplete
client
capability
controls whether to send realm_user
events with op: "add"
containing "Unknown user" placeholder objects to clients when a new
user is created that the client does not have access to due to a
can_access_all_users_group
policy.
Feature level 231
-
POST /register
:

now represents more accurately
whether push notifications are actually enabled via the mobile push
notifications service. Added

update event is now sent
whenever push_notifications_enabled
or
push_notifications_enabled_end_timestamp

large numbers of participants are now restricted by
wildcard_mention_policy

error codes when a message is
rejected because of wildcard_mention_policy
.
Feature level 228
-

-
POST /remotes/server/register
: The ios_app_id
parameter is now
required when kind
is 1, i.e. when registering an APNs token.

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.
-
GET /events
: When a bot is deactivated or
reactivated, the server sends realm_bot

Feature level 221
POST /register

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.

now use this endpoint to create reusable invitation links. Previously,
this endpoint was restricted to admin users only.
-
GET /invites

created. Previously, non-admin users could only create email invitations, and
therefore the response did not include reusable invitation links for these

users can now revoke reusable invitation links they have created. Previously,
only admin users could create and revoke reusable invitation links.

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
Feature level 193
Feature level 192
GET /events
: Stream creation events are now
sent when guest users gain access to a public stream by being

realm setting move_messages_within_stream_limit_seconds
, see feature
level 162.
GET /events
: Removed the community_topic_editing_limit_seconds

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
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"

the modern convention with servers that support it, because support for
"private"
may eventually be removed.

Feature level 169
Feature level 168
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,

GET /users/{email}
,

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.

, PATCH /settings
,
PATCH /realm/user_settings_defaults
:
Added user setting email_address_visibility

administrators and moderators, the time limit for editing topics is now
controlled via the realm setting move_messages_within_stream_limit_seconds

for the stream.
Feature level 160
POST /api/v1/jwt/fetch_api_key
: Added new endpoint to fetch API

,
GET /events
:
Nobody added as an option for the realm settings edit_topic_policy

messages within a narrow.
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

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

property. Prior to this feature level, only one event was
sent to clients with the deprecated in_home_view

field
is still present for backwards compatibility with older server versions.

using the attachment was sent is now correctly encoded as
date_sent
, replacing the confusingly named name

floats incorrectly suggesting that microsecond precision is
relevant).

Feature level 15
