About WAppOTP

WAppOTP is a developer API for sending one-time passwords and transactional messages over WhatsApp using a number you link by QR code, with prepaid SMS for Philippine mobile numbers. It is owned and operated by PRINTABLES.PH CONSUMER GOODS TRADING, DTI Business Reg. No. 697296683, Republic of the Philippines.

We built WAppOTP because small and growing businesses needed phone verification and order updates on WhatsApp without weeks of Meta onboarding or per-message fees. Link the number you already have, and ship.
