meta-whatsapp

Send WhatsApp messages and manage Meta WhatsApp Business API credentials directly from Claude.

Overview

This plugin gives Claude two skills for working with the Meta WhatsApp Business API:

• send — send text or template messages to one or more recipients
• configure — save, check, update, or clear your API credentials

Credentials are stored locally at ~/.claude/channels/whatsapp/.env and never transmitted except as part of authorized API calls to Meta's Graph API.

Setup

Before sending messages, you need a Meta for Developers account with a WhatsApp Business app configured.

1. Go to developers.facebook.com → your WhatsApp Business app → API Setup
2. Note your Phone Number ID (numeric string under your phone number)
3. Generate a temporary (24 h) or permanent (system-user) Access Token
4. In Claude, say: "Configure WhatsApp with phone number ID <id> and access token <token>"
