+
+Zalo channel plugin for Clawdbot (Bot API).
+
+## Install (local checkout)
+
+```bash
+clawdbot plugins install ./extensions/zalo
+```
+
+## Install (npm)
+
+```bash
+clawdbot plugins install @clawdbot/zalo
+```
+
+Onboarding: select Zalo and confirm the install prompt to fetch the plugin automatically.
+
+## Config
+
+```json5
+{
+  channels: {
+    zalo: {
+      enabled: true,
+      botToken: "12345689:abc-xyz",
+      dmPolicy: "pairing",
+      proxy: "http://proxy.local:8080"
+    }
+  }
+}
+```
+
+## Webhook mode
+
+```json5
+{
+  channels: {
+    zalo: {
+      webhookUrl: "https://example.com/zalo-webhook",
+      webhookSecret: "your-secret-8-plus-chars",
+      webhookPath: "/zalo-webhook"
+    }
+  }
+}
+```
+
+If `webhookPath` is omitted, the plugin uses the webhook URL path.
+
+Restart the gateway after config changes.
