Reverse OTP flips the flow. Your user sends one WhatsApp message to your number and LoginWA verifies it. Your number sends nothing, so there is no OTP to report as spam and nothing that counts toward WhatsApp's cap on unanswered messages.
Send codes, order updates, promos, and auto-replies on WhatsApp. Free 100 messages/month. Paid plans from $1 (1,000 messages) up to $7 (10,000). Pay by card, PayPal, Apple Pay, or Google Pay.
