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

Install the plugin:

openclaw plugins install @openclaw/zalo

Configure bot token via environment variable (ZALO_BOT_TOKEN) or config file
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:

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
