WhatsApp & Telegram messaging
You are wiring code that pushes messages to real customers. Both platforms have sharp, silent rules: code that passes in testing 403s or drops in production. This skill is the transport pipe — endpoints, auth, windows, rate limits, webhooks. The words you send are out of scope (that is ../customer-support/SKILL.md).
Pick your platform
| If the customer is... | Use | Why |
|---|---|---|
| already on WhatsApp, identity-verified, you have their phone number | WhatsApp Cloud API | Highest reach + trust; but template-gated and billed per message. |
| an opt-in bot subscriber (clicked "Start") | Telegram Bot API | Free, instant, dev-friendly, no template gate, but reach = people who joined your bot. |
You can ship both — but the rules do not transfer. WhatsApp's 24-hour window and template gate have no Telegram equivalent; Telegram's 30 msg/s ceiling has no WhatsApp equivalent.
