Everything You Need To Know
No. WhatsAPI uses direct multi-device session emulation via GenesisWay Cloud Gateway. You simply scan a QR code from your phone (business or personal WhatsApp) and start sending immediately.
None. Unlike official Meta Cloud API which charges ₹0.80 - ₹1.20 per marketing conversation, WhatsAPI charges only a fixed monthly subscription. All messages within your plan quota are 100% free.
We use our secure GenesisUPI gateway (genesisupi.com). You scan a standard UPI QR code (Google Pay, PhonePe, Paytm, or BHIM). Once paid, your plan is automatically credited for 30 days in real-time.
