+# Zalo Bot Integration
+
+## Overview
+
+Zalo is a Vietnam-focused messaging platform with Bot API support. This documentation describes setting up a Zalo bot channel for direct messaging through OpenClaw's gateway system.
+
+## Setup Steps
+
+1. **Install the plugin:**
+
+```bash
+openclaw plugins install @openclaw/zalo
+```
+
+2. **Configure bot token** via environment variable (`ZALO_BOT_TOKEN`) or config file
+
+3. **Restart the gateway** to activate the channel
+
+## Core Capabilities
+
+The integration supports:
+
+- **Direct messages** only (groups "coming soon" per Zalo documentation)
+- **Text messages** with 2000-character chunking
+- **Image handling** for inbound/outbound media
+- **Deterministic routing** ensuring replies return to Zalo
+
+## Access Control
+
+By default, unknown senders receive a pairing code that expires after one hour. Approval is managed through CLI commands:
+
+```bash
+openclaw pairing approve zalo <CODE>
+```
+
+Alternative policies include allowlisting specific user IDs.
+
+## Technical Constraints
+
+- The 2000-character output limit makes streaming blocked by default since it reduces practical utility
+- Media uploads and downloads are capped at 5 MB by default
+- Stickers and unsupported message types are logged but not processed
+
+## Deployment Options
+
+The channel supports two modes (mutually exclusive per Zalo API specifications):
+
+### Long-Polling (Default)
+
+No additional configuration required.
+
+### Webhook Mode
+
+Requires:
+
+- HTTPS endpoint
+- A secret token between 8-256 characters
