feishu-thread-forward（飞书线程转发）

Feishu Thread Forward

Forward a Feishu thread (话题) to a user, group, or another topic using the Feishu Open API.

When to Use

• User asks to forward/share a thread or topic to another group or user
• You need to cross-post a topic post from one group to another
• The built-in message tool cannot do thread-level forwarding

API

POST https://open.feishu.cn/open-apis/im/v1/threads/{thread_id}/forward?receive_id_type={type}

Parameters

Headers

Authorization: Bearer {tenant_access_token}
Content-Type: application/json

How to Get thread_id

A message in a topic group has a thread_id field. Retrieve it via:

GET https://open.feishu.cn/open-apis/im/v1/messages/{message_id}

The response data.items[0].thread_id contains the thread ID (e.g., omt_1accc5a75c0f9b93).

Script

Use scripts/forward_thread.py for the complete implementation.

python3 skills/feishu-thread-forward/scripts/forward_thread.py \
  --thread-id omt_xxxxx \
  --receive-id oc_xxxxx \
  --receive-id-type chat_id

Typical Flow

1. Get thread_id — from the message's metadata, or by calling GET message API
2. Call forward API — POST /im/v1/threads/{thread_id}/forward
3. Result — a merge_forward type message appears in the target chat as a clickable topic card

Forward vs Merge Forward vs Message Forward

Thread forward is what users see when they click "转发话题" in Feishu client.

Prerequisites

• Bot must be in the source group (and can see the thread)
• Bot must be in the target group (or target user must be in bot's availability scope)
• Bot needs im:message or im:message:send_as_bot permission

Credentials

Read from /root/.openclaw/openclaw.json → channels.feishu.appId / channels.feishu.appSecret to obtain tenant_access_token.
