## Introduction
WhatsApp is the world's most popular messaging platform with over 2 billion active users across 180 countries. For businesses deploying AI agents, WhatsApp represents the single largest channel opportunity β customers are already there, already comfortable, and already expecting instant responses. Both OpenClaw and EClaw offer WhatsApp integration paths, but their architectural approaches differ significantly. This comparison examines how each platform handles WhatsApp connectivity, message routing, agent management, and the trade-offs involved in choosing one approach over the other.
## Platform Overview
WhatsApp offers two integration paths for developers: the WhatsApp Business API (official, cloud-hosted by Meta) and WhatsApp Web (browser-based protocol). The Business API provides enterprise features like message templates, interactive buttons, catalog integration, and verified business profiles. WhatsApp Web, while more accessible, operates through reverse-engineered protocols and lacks official support for business-grade features.
The choice between these paths fundamentally shapes what an AI agent platform can offer. Message throughput, session stability, rich media support, and compliance all depend on which integration layer sits beneath the agent framework.
## OpenClaw Integration Analysis
OpenClaw connects to WhatsApp through its built-in WhatsApp Web channel powered by the Baileys library. Setup is straightforward β a QR code scan links your WhatsApp account to the OpenClaw gateway.
**Setup Configuration:**
```json
{
"channels": {
"whatsapp": {
"dmPolicy": "pairing",
"allowFrom": ["+15551234567"],
"groupPolicy": "allowlist",
"groupAllowFrom": ["+15551234567"]
}
}
}
```
**Key Commands:**
```bash
openclaw channels login --channel whatsapp
openclaw channels login --channel whatsapp --account work
openclaw gateway
```
OpenClaw's WhatsApp integration supports direct messages, group chats (with allowlist policies), media attachments (images, voice, video, documents), and multi-account setups. The pairing system allows controlled onboarding of new contacts, and channel routing can direct different conversations to different agents.
However, since it uses WhatsApp Web (Baileys), sessions may disconnect periodically requiring QR re-authentication. There's no support for WhatsApp Business-specific features like message templates, interactive buttons, or product catalogs. The platform recommends using a dedicated phone number rather than your personal number for cleaner operational boundaries.
## EClaw Integration Analysis
EClaw takes a different architectural approach. Rather than implementing WhatsApp connectivity directly, EClaw leverages the OpenClaw ecosystem as its channel layer. Each EClaw entity (AI agent) can receive messages through OpenClaw's WhatsApp channel via webhook push notifications.
**Entity Webhook Pattern:**
```bash
# EClaw receives WhatsApp messages via OpenClaw webhook push
POST /tools/invoke
{
"tool": "sessions_send",
"args": {
"sessionKey": "agent:main:main",
"message": "[Device xxx Entity 0]\nSource: whatsapp\nContent: Hello!"
}
}
```
**Bot Reply via Transform API:**
```bash
curl -s -X POST "https://eclawbot.com/api/transform" \
-H "Content-Type: application/json" \
-d '{
"deviceId": "DEVICE_ID",
"entityId": 0,
"botSecret": "BOT_SECRET",
"message": "Hi! How can I help you today?",
"state": "IDLE"
}'
```
EClaw's strength lies in its multi-entity architecture. A single device can run multiple AI agents (entities), each with its own personality (Soul), behavior rules, identity, and Agent Card. The Mission Dashboard provides task management, notes, and scheduling. Cross-device communication via public codes enables entity-to-entity collaboration that extends beyond a single WhatsApp conversation.
