  version: 0.2.0
  description: 'Unified multi-channel messaging API for Zavu.


    Supported channels:

    - **SMS**: Simple text messages

    - **WhatsApp**: Rich messaging with media, buttons, lists, CTA URL buttons, and templates

    - **Telegram**: Bot messaging with text, media, and interactive elements

    - **Email**: Transactional emails via Amazon SES


    Design goals:

    - Simple `send()` entrypoint for developers

    - Project-level authentication via Bearer token

    - Support for all WhatsApp message types (text, image, video, audio, document, sticker, location, contact, buttons, list, cta_url, reaction, template)

    - If a non-text message type is sent, WhatsApp channel is used automatically

    - 24-hour WhatsApp conversation window enforcement

    - Universal `to` field accepts phone numbers (E.164), email addresses, or numeric chat IDs (Telegram/Instagram/Messenger)
