Multi-channel message delivery
One API sends a templated message to a contact over WhatsApp, SMS, Viber, Telegram, or email. When a channel fails, connect falls through to the next one in your policy and tells you what happened on each.
WhatsApp, SMS, Viber, Telegram, and email through a single API. A cascade policy orders the channels per organisation; a failed or timed-out attempt moves to the next one.
Write a template once per channel with placeholders, and send it with a data object. Every version is kept, and every message remembers the version it was sent with.
Send returns at once with a message id. Delivery runs in the background, provider webhooks confirm it, and the dashboard shows every attempt on every channel.
Four calls cover the common path. Authenticate with an API key from the dashboard.
