WhatsApp Business API

Official Meta Cloud API integration. See auxiliary files for detailed operations.

  -H "Authorization: Bearer $WHATSAPP_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"messaging_product":"whatsapp","to":"1234567890","type":"text","text":{"body":"Hello!"}}'

Setup

On first use, read setup.md. Preferences stored in ~/whatsapp-business-api/memory.md.

When to Use

Any WhatsApp Business operation: send messages, templates, media, interactive elements, manage webhooks, handle conversations, update business profiles.

Quick Reference

Core Rules

1. International format — Phone numbers without + or leading zeros: 1234567890
2. 24-hour window — Free replies within 24h of customer message; templates required to initiate
3. Template approval — Templates need Meta approval (24-48h); test in sandbox first
4. Idempotency — Use biz_opaque_callback_data to track message state
5. Webhook verification — Always verify webhook signature with app secret

6. Rate limits — 80 messages/second per phone number; 1000 template messages/day (tier 1)
7. Media limits — Images <5MB, videos <16MB, documents <100MB

Authentication

Required environment variables: - WHATSAPP_ACCESS_TOKEN — System User access token (permanent) or User access token (60-day) - WHATSAPP_PHONE_NUMBER_ID — Your registered phone number ID - WHATSAPP_BUSINESS_ACCOUNT_ID — Your WABA ID (for templates) - WHATSAPP_APP_SECRET — App secret for webhook verification

curl "https://graph.facebook.com/v21.0/$WHATSAPP_PHONE_NUMBER_ID" \
  -H "Authorization: Bearer $WHATSAPP_ACCESS_TOKEN"

Token Types

Common Traps

• Phone format with + or 00 → API rejects
• Missing messaging_product: "whatsapp" → 400 error
• Template not approved → message fails silently
• Webhook signature not verified → security vulnerability
• Sending outside 24h window without template → blocked

External Endpoints

Security & Privacy

Environment variables used: - WHATSAPP_ACCESS_TOKEN — for API authentication - WHATSAPP_APP_SECRET — for webhook signature verification

Sent to Meta: Messages, media, customer phone numbers via graph.facebook.com Stays local: Tokens (never logged), ~/whatsapp-business-api/ preferences Never: Log message content, skip webhook verification, store tokens in code

這個 Skill 質量還不錯，文件寫得比較全面，涵蓋了 WhatsApp 訊息傳送的各個方面，示例清晰易懂。好的地方是結構清晰、容易查詢內容。但它主要是教你怎麼用 API，不是現成的工具，需要開發者自己寫程式碼才能用。如果你想找個能直接用的工具可能會失望，但作為學習參考是夠用的。
