+or leading zeros:1234567890 - 24-hour window — Free replies within 24h of customer message; templates required to initiate
- Template approval — Templates need Meta approval (24-48h); test in sandbox first
- Idempotency — Use
biz_opaque_callback_datato track message state - Webhook verification — Always verify webhook signature with app secret
- Rate limits — 80 messages/second per phone number; 1000 template messages/day (tier 1)
- Media limits — Images <5MB, videos <16MB, documents <100MB
