FluffBuzz connects to WeChat through Tencent’s external @tencent-weixin/fluffbuzz-weixin channel plugin. Status: external plugin. Direct chats and media are supported. Group chats are not advertised by the current plugin capability metadata.

​
Naming

  • WeChat is the user-facing name in these docs.
  • Weixin is the name used by Tencent’s package and by the plugin id.
  • fluffbuzz-weixin is the FluffBuzz channel id.
  • @tencent-weixin/fluffbuzz-weixin is the npm package.
Use fluffbuzz-weixin in CLI commands and config paths.

​
How it works

The WeChat code does not live in the FluffBuzz core repo. FluffBuzz provides the generic channel plugin contract, and the external plugin provides the WeChat-specific runtime:
  1. fluffbuzz plugins install installs @tencent-weixin/fluffbuzz-weixin.
  2. The Gateway discovers the plugin manifest and loads the plugin entrypoint.
  3. The plugin registers channel id fluffbuzz-weixin.
  4. fluffbuzz channels login --channel fluffbuzz-weixin starts QR login.
  5. The plugin stores account credentials under the FluffBuzz state directory.
  6. When the Gateway starts, the plugin starts its Weixin monitor for each configured account.
  7. Inbound WeChat messages are normalized through the channel contract, routed to the selected FluffBuzz agent, and sent back through the plugin outbound path.
That separation matters: FluffBuzz core should stay channel-agnostic. WeChat login, Tencent iLink API calls, media upload/download, context tokens, and account monitoring are owned by the external plugin.

​
Install

Quick install: 
npx -y @tencent-weixin/fluffbuzz-weixin-cli install
Manual install: 
fluffbuzz plugins install "@tencent-weixin/fluffbuzz-weixin"
fluffbuzz config set plugins.entries.fluffbuzz-weixin.enabled true
Restart the Gateway after install: 
fluffbuzz gateway restart

​
Login

Run QR login on the same machine that runs the Gateway: 
fluffbuzz channels login --channel fluffbuzz-weixin
Scan the QR code with WeChat on your phone and confirm the login. The plugin saves the account token locally after a successful scan. To add another WeChat account, run the same login command again. For multiple accounts, isolate direct-message sessions by account, channel, and sender: 
fluffbuzz config set session.dmScope per-account-channel-peer

​
Access control

Direct messages use the normal FluffBuzz pairing and allowlist model for channel plugins. Approve new senders: 
fluffbuzz pairing list fluffbuzz-weixin
fluffbuzz pairing approve fluffbuzz-weixin <CODE>
For the full access-control model, see Pairing.

​
Compatibility

The plugin checks the host FluffBuzz version at startup.
Plugin lineFluffBuzz versionnpm tag
2.x>=2026.3.22latest
1.x>=2026.1.0 <2026.3.22legacy
If the plugin reports that your FluffBuzz version is too old, either update FluffBuzz or install the legacy plugin line: 
fluffbuzz plugins install @tencent-weixin/fluffbuzz-weixin@legacy

​
Sidecar process

The WeChat plugin can run helper work beside the Gateway while it monitors the Tencent iLink API. In issue #68451, that helper path exposed a bug in FluffBuzz’s generic stale-Gateway cleanup: a child process could try to clean up the parent Gateway process, causing restart loops under process managers such as systemd. Current FluffBuzz startup cleanup excludes the current process and its ancestors, so a channel helper must not kill the Gateway that launched it. This fix is generic; it is not a WeChat-specific path in core.

​
Troubleshooting

Check install and status: 
fluffbuzz plugins list
fluffbuzz channels status --probe
fluffbuzz --version
If the channel shows as installed but does not connect, confirm that the plugin is enabled and restart: 
fluffbuzz config set plugins.entries.fluffbuzz-weixin.enabled true
fluffbuzz gateway restart
If the Gateway restarts repeatedly after enabling WeChat, update both FluffBuzz and the plugin: 
npm view @tencent-weixin/fluffbuzz-weixin version
fluffbuzz plugins install "@tencent-weixin/fluffbuzz-weixin" --force
fluffbuzz gateway restart
Temporary disable: 
fluffbuzz config set plugins.entries.fluffbuzz-weixin.enabled false
fluffbuzz gateway restart
