It is useful both for Zulip clients (e.g. the web, desktop, mobile, and terminal clients) as well as bots, API clients, backup scripts, etc. By specifying a [narrow filter](/api/construct-narrow), you can use this endpoint to fetch the messages matching any search query that is supported by Zulip's powerful full-text search backend. When a narrow is not specified, it can be used to fetch a user's message history (We recommend paginating to 1000 messages at a time). In either case, you specify an `anchor` message (or ask the server to calculate the first unread message for you and use that as the anchor), as well as a number of messages before and after the anchor message. The server returns those messages, sorted by message ID, as well as some metadata that makes it easy for a client to determine whether there are more messages matching the query that were not returned due to the `num_before` and `num_after` limits. We recommend using `num_before <= 1000` and `num_after <= 1000` to avoid generating very large HTTP responses. A maximum of 5000 messages can be obtained per request; attempting to exceed this will result in an error. parameters: - name: anchor in: query description: | Integer message ID to anchor fetching of new messages. Supports special string values for when the client wants the server to compute the anchor to use: * `newest`: The most recent message. * `oldest`: The oldest message. * `first_unread`: The oldest unread message matching the query, if any; otherwise, the most recent message. The special values of `'newest'` and `'oldest'` are also supported for anchoring the query at the most recent or oldest messages. **Changes**: String values are new in Zulip 2.2 (feature level 1). The `first_unread` functionality was supported in Zulip 2.1.x and older by not sending anchor and using use_first_unread_anchor. In Zulip 2.1.x and older, `oldest` can be emulated with `anchor=0`, and `newest` with `anchor=10000000000000000` (that specific large value works around a bug in Zulip 2.1.x and older in the `found_newest` return value). schema: oneOf: - type: string - type: integer example: 42 - name: num_before in: query description: | The number of messages with IDs less than the anchor to retrieve. schema: type: integer example: 4 required: true - name: num_after in: query description: | The number of messages with IDs greater than the anchor to retrieve. schema: type: integer example: 8 required: true - name: narrow in: query description: | The narrow where you want to fetch the messages from.

Only required for stream messages (`type="stream"`), ignored otherwise. Maximum length of 60 characters. schema: type: string example: Castle QueueId: name: queue_id in: query description: | The ID of an event queue that was previously registered via `POST /api/v1/register` (see [Register a queue](/api/register-queue)). schema: type: string example: 1375801870:2942 required: true Stream: name: stream in: query description: | The name of the stream to access. schema: type: string example: Denmark StreamIdInQuery: name: stream_id in: query description: | The ID of the stream to access. schema: type: integer example: 42 StreamIdInPath: name: stream_id in: path description: | The ID of the stream to access. schema: type: integer example: 42 required: true ClientGravatar: name: client_gravatar in: query description: | Whether the client supports computing gravatars URLs. If enabled, `avatar_url` will be included in the response only if there is a Zulip avatar, and will be `null` for users who are using gravatar as their avatar. This option significantly reduces the compressed size of user data, since gravatar URLs are long, random strings and thus do not compress well. The `client_gravatar` field is set to `true` if clients can compute their own gravatars. schema: type: boolean default: false example: true Content: name: content in: query description: | The content of the message. Maximum message size of 10000 bytes. schema: type: string example: Hello required: true MessageId: name: message_id in: path description: | The target message's ID. schema: type: integer example: 42 required: true UserId: name: user_id in: path description: | The target user's ID. schema: type: integer example: 12 required: true StreamPostPolicy: name: stream_post_policy in: query description: | Policy for which users can post messages to the stream. * 1 => Any user can post. * 2 => Only administrators can post. * 3 => Only new members can post. **Changes**: New in Zulip 2.2, replacing the previous `is_announcement_only` boolean. schema: type: integer default: 1 example: 2 required: false HistoryPublicToSubscribers: name: history_public_to_subscribers in: query description: | Whether the stream's message history should be available to newly subscribed members, or users can only access messages they actually received while subscribed to the stream. Corresponds to the [shared history](/help/stream-permissions) option in documentation. schema: type: boolean default: None example: false required: false IncludeSubscribers: name: include_subscribers in: query description: | Whether each returned stream object should include a `subscribers` field containing a list of the user IDs of its subscribers. (This may be significantly slower in organizations with thousands of users subscribed to many streams.) **Changes**: New in Zulip 2.1.0. schema: type: boolean default: false example: true EmojiName: name: emoji_name in: query description: | The target emoji's human-readable name. To find an emoji's name, hover over a message to reveal three icons on the right, then click the smiley face icon. Images of available reaction emojis appear. Hover over the emoji you want, and note that emoji's text name. schema: type: string example: 'octopus' IncludeCustomProfileFields: name: include_custom_profile_fields in: query description: | Whether the client wants [custom profile field](/help/add-custom-profile-fields) data to be included in the response. **Changes**: New in Zulip 2.1.0. Previous versions do no offer these data via the API. schema: type: boolean default: false example: true Principals: name: principals in: query description: | A list of email addresses of the users that will be subscribed/unsubscribed to the streams specified in the `subscriptions` argument. If not provided, then the requesting user/bot is subscribed. schema: type: array items: type: string default: [] example: ['ZOE@zulip.com'] ReactionType: name: reaction_type in: query description: | If an app is adding/removing a vote on an existing reaction, it should pass this parameter using the value the server provided for the existing reaction for specificity. Supported values: * `unicode_emoji`: Unicode emoji (`emoji_code` will be its unicode codepoint). * `realm_emoji`: Custom emoji. (`emoji_code` will be its ID). * `zulip_extra_emoji`: Special emoji included with Zulip. Exists to namespace the `zulip` emoji. **Changes**: In Zulip 2.2 (feature level 2), this become optional for [custom emoji](/help/add-custom-emoji); previously, this endpoint assumed `unicode_emoji` if this parameter was not specified. schema: type: string example: 'unicode_emoji' required: false EmojiCode: name: emoji_code in: query description: | A unique ID, defining the specific emoji codepoint requested, within the namespace of the `reaction_type`. For most API clients, you won't need this, but it's important for Zulip apps to handle rare corner cases when adding/removing votes on an emoji reaction added previously by another user. If the existing reaction was added when the Zulip server was using a previous version of the emoji data mapping between Unicode codepoints and human-readable names, sending the `emoji_code` in the data for the original reaction allows the Zulip server to correctly interpret your upvote as an upvote rather than a reaction with a "diffenent" emoji. schema: type: string example: '1f419' required: false
