Deliver one-time passwords, TAC codes, and 2FA verification via WhatsApp — faster delivery, higher open rates, and lower cost than traditional SMS OTP in Malaysia.
WhatsApp has over 25 million active users in Malaysia. Your customers already have it installed — delivering OTP via WhatsApp means higher read rates and faster verification.
WhatsApp messages are delivered over data connection — typically faster than SMS routing through telco networks in Malaysia.
WhatsApp messages are read almost immediately. Customers are more likely to see and act on a WhatsApp OTP than an SMS.
WhatsApp works on WiFi — customers in areas with poor GSM coverage but WiFi access can still receive their OTP.
Your verified business name and profile appear on the OTP message — customers trust it more than an unknown SMS sender ID.
Include your logo, business name, and formatted OTP instructions — not just a plain text SMS.
Configure automatic fallback to SMS OTP if the customer does not have WhatsApp — best of both channels.
One API call to send WhatsApp OTP — same endpoint handles both WhatsApp and SMS fallback.
