+summary: "WeChat channel setup through the external openclaw-weixin plugin"
+read_when:
+  - You want to connect OpenClaw to WeChat or Weixin
+  - You are installing or troubleshooting the openclaw-weixin channel plugin
+  - You need to understand how external channel plugins run beside the Gateway
+title: "WeChat"
+---
+
+OpenClaw connects to WeChat through Tencent's external
+`@tencent-weixin/openclaw-weixin` channel plugin.
+
+Status: external plugin, maintained by the Tencent Weixin team. Direct chats and
+media are supported. Group chats are not advertised by the plugin capability
+metadata (it declares direct chats only).
+
+## Naming
+
+- **WeChat** is the user-facing name in these docs.
+- **Weixin** is the name used by Tencent's package and by the plugin id.
+- `openclaw-weixin` is the OpenClaw channel id (`weixin` and `wechat` work as aliases).
+- `@tencent-weixin/openclaw-weixin` is the npm package.
+
+Use `openclaw-weixin` in CLI commands and config paths.
+
+## How it works
+
+The WeChat code does not live in the OpenClaw core repo. OpenClaw provides the
+generic channel plugin contract, and the external plugin provides the
+WeChat-specific runtime:
+
+1. `openclaw plugins install` installs `@tencent-weixin/openclaw-weixin`.
+2. The Gateway discovers the plugin manifest and loads the plugin entrypoint.
+3. The plugin registers channel id `openclaw-weixin`.
+4. `openclaw channels login --channel openclaw-weixin` starts QR login.
+5. The plugin stores account credentials under the OpenClaw state directory
+   (`~/.openclaw` by default).
+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 OpenClaw agent, and sent back through the plugin outbound path.
+
+That separation matters: OpenClaw core stays 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:
+
+```bash
+npx -y @tencent-weixin/openclaw-weixin-cli install
+```
+
+Manual install:
+
+```bash
+openclaw plugins install "@tencent-weixin/openclaw-weixin"
+openclaw config set plugins.entries.openclaw-weixin.enabled true
+```
+
+Restart the Gateway after install:
+
+```bash
+openclaw gateway restart
+```
+
+## Login
+
+Run QR login on the same machine that runs the Gateway:
+
+```bash
+openclaw channels login --channel openclaw-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:
+
+```bash
+openclaw config set session.dmScope per-account-channel-peer
+```
+
+## Access control
+
+Direct messages use the normal OpenClaw pairing and allowlist model for channel
+plugins.
+
+Approve new senders:
+
+```bash
+openclaw pairing list openclaw-weixin
+openclaw pairing approve openclaw-weixin <CODE>
+```
+
+For the full access-control model, see [Pairing](/channels/pairing).
+
+## Compatibility
+
+The plugin checks the host OpenClaw version at startup.
+
+| Plugin line | OpenClaw version                                                | npm tag  |
+| ----------- | --------------------------------------------------------------- | -------- |
+| `2.x`       | `>=2026.5.12` (current 2.4.6; early 2.x accepted `>=2026.3.22`) | `latest` |
+| `1.x`       | `>=2026.1.0 <2026.3.22`                                         | `legacy` |
+
+If the plugin reports that your OpenClaw version is too old, either update
+OpenClaw or install the legacy plugin line:
+
+```bash
+openclaw plugins install @tencent-weixin/openclaw-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 OpenClaw'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 OpenClaw startup cleanup excludes the current process and its ancestors,
+so a channel helper cannot kill the Gateway that launched it. This fix is
+generic; it is not a WeChat-specific path in core.
+
+## Troubleshooting
+
+Check install and status:
+
+```bash
+openclaw plugins list
+openclaw channels status --probe
+openclaw --version
+```
+
+If the channel shows as installed but does not connect, confirm that the plugin is
+enabled and restart:
+
+```bash
+openclaw config set plugins.entries.openclaw-weixin.enabled true
+openclaw gateway restart
+```
+
+If the Gateway restarts repeatedly after enabling WeChat, update both OpenClaw and
+the plugin:
+
+```bash
+npm view @tencent-weixin/openclaw-weixin version
+openclaw plugins install "@tencent-weixin/openclaw-weixin" --force
+openclaw gateway restart
+```
+
+If startup reports that the installed plugin package `requires compiled runtime
+output for TypeScript entry`, the npm package was published without the compiled
+JavaScript runtime files OpenClaw needs. Update/reinstall after the plugin
+publisher ships a fixed package, or temporarily disable/uninstall the plugin.
+
+Temporary disable:
+
+```bash
+openclaw config set plugins.entries.openclaw-weixin.enabled false
+openclaw gateway restart
+```
