What is Zernio Whatsapp Api?

Zernio simplifies Meta's complex WhatsApp Cloud API into a single, clean REST API. Instead of navigating multiple Meta products, handling opaque template approvals, and building retry infrastructure, developers get one API key and can start sending messages in 30 seconds. It abstracts away rate limits, messaging tiers, 24-hour windows, and webhook management - letting teams ship WhatsApp integrations in weeks instead of months.
