Core Concepts

• Message : A single message in a chat, identified by message_id (om_xxx). Supports types: text, post, image, file, audio, video, sticker, interactive (card), share_chat, share_user, merge_forward, etc.
• Chat : A group chat or P2P conversation, identified by chat_id (oc_xxx).
• Thread : A reply thread under a message, identified by thread_id (om_xxx or omt_xxx).
• Reaction : An emoji reaction on a message.

Resource Relationships

Chat (oc_xxx)
├── Message (om_xxx)
│   ├── Thread (reply thread)
│   ├── Reaction (emoji)
│   └── Resource (image / file / video / audio)
└── Member (user / bot)

Important Notes

Identity and Token Mapping

• --as user means user identity and uses user_access_token. Calls run as the authorized end user, so permissions depend on both the app scopes and that user's own access to the target chat/message/resource.
• --as bot means bot identity and uses tenant_access_token. Calls run as the app bot, so behavior depends on the bot's membership, app visibility, availability range, and bot-specific scopes.
• If an IM API says it supports both user and bot, the token type changes who the operator is. The same API can succeed with one identity and fail with the other because owner/admin status, chat membership, tenant boundary, or app availability are checked against the current caller.

Sender Name Resolution with Bot Identity

When using bot identity (--as bot) to fetch messages (e.g. +chat-messages-list, +threads-messages-list, +messages-mget), sender names may not be resolved (shown as open_id instead of display name). This happens when the bot cannot access the user's contact info.

Root cause : The bot's app visibility settings do not include the message sender, so the contact API returns no name.

Solution : Check the app's visibility settings in the Lark Developer Console — ensure the app's visible range covers the users whose names need to be resolved. Alternatively, use --as user to fetch messages with user identity, which typically has broader contact access.

Card Messages (Interactive)

Card messages (interactive type) are not yet supported for compact conversion in event subscriptions. The raw event data will be returned instead, with a hint printed to stderr.

Shortcuts（推荐优先使用）

Shortcut 是对常用操作的高级封装（lark-cli im +<verb> [flags]）。有 Shortcut 的操作优先使用。

API Resources

lark-cli schema im.<resource>.<method>   # 调用 API 前必须先查看参数结构
lark-cli im <resource> <method> [flags] # 调用 API

重要 ：使用原生 API 时，必须先运行 schema 查看 --data / --params 参数结构，不要猜测字段格式。

chats

messages

• delete — 撤回消息。Identity: supports user and bot; for bot calls, the bot must be in the chat to revoke group messages; to revoke another user's group message, the bot must be the owner, an admin, or the creator; for user P2P recalls, the target user must be within the bot's availability.
• forward — 转发消息。Identity: bot only (tenant_access_token).
• merge_forward — 合并转发消息。Identity: bot only (tenant_access_token).
• — 查询消息已读信息。Identity: only (); the bot must be in the chat, and can only query read status for messages it sent within the last 7 days.

reactions
