Authentication Templates — WhatsApp Business API OTP & Verification Code Templates

Send WhatsApp Business API authentication messages, OTP codes, and two-factor verification — fixed Meta-approved format, instant delivery, security recommendation, and code expiry options. Trusted by 1,000+ Indian businesses.

WABA NXCMSG WhatsApp Business API Authentication Templates allow businesses to send OTP (One-Time Passwords), verification codes, and two-factor authentication messages directly to customers on WhatsApp — using a Meta-approved, fixed-format message that is instantly recognisable, secure, and delivered with 99.9% uptime. WhatsApp Business API Authentication templates are specifically designed for login verification, account confirmation, password reset codes, transaction authentication, and KYC verification — making them the most trusted OTP delivery channel in India, with a 98% open rate compared to 45% for SMS OTP. Unlike Marketing and Utility templates, WhatsApp API Authentication templates use a standardised, non-editable message body — "1 is your verification code." — where the OTP is dynamically inserted at the time of sending, ensuring every customer receives a clear, tamper-proof verification message that meets WhatsApp Business API security compliance standards. With WABA NXCMSG WhatsApp Business API template builder, businesses can create Authentication templates with two powerful Additional Options — Add security recommendation, which appends "For your security, do not share this code" to the WhatsApp API message body, and Add expiration time for the code, which adds code validity duration to the message footer — both recommended for banking OTP, fintech authentication, eCommerce login, and healthcare portal verification use cases. A real-time Live Preview shows businesses exactly how the WhatsApp Business API Authentication template will appear on the customer's WhatsApp — including the OTP code placeholder, optional security text, and expiry footer — before submitting for Meta approval. Multi-language support including English and regional Indian languages ensures every Indian business can send WhatsApp API OTP messages in the customer's preferred language, maximising verification completion rates across all geographies. All WABA NXCMSG WhatsApp Business API Authentication templates are reviewed and approved by Meta before they can be used — a process that typically takes just a few minutes — ensuring full compliance with WhatsApp Business API policies and readiness for high-volume OTP delivery. WhatsApp API Authentication templates are not subject to India's TRAI DND regulations, meaning they reach every customer including DND-registered numbers — eliminating the 15–25% OTP delivery failure rate that Indian businesses face with SMS OTP. Once approved, Authentication templates can be reused across login flows, signup verification, transaction confirmation, and password reset automation — giving Indian businesses a ready-to-use WhatsApp Business API OTP template for every authentication scenario. As an official Meta Business Partner, WABA NXCMSG provides India's most complete WhatsApp Business API template management platform with Marketing, Utility, and Authentication template support, live preview, dynamic variables, and 99.9% uptime guarantee.
