WhatsApp Automation

What is the difference between OpenWA and the Meta WhatsApp API?

OpenWA sends WhatsApp messages via a QR-linked session at zero per-message cost, which suits small businesses sending bills, statements and alerts. The Meta WhatsApp API is the official business messaging route, with approved message templates, higher reliability at scale, and per-message charges set by Meta. OpenBill Pro offers OpenWA dispatch in its core plans and the Meta WhatsApp API in its Pro plan at ₹99/month, so a business can start cheap and upgrade when volume or formality demands it. The choice depends on how many messages you send and whether you need approved templates.
