What is WhatsApp OTP & Authentication API?

SMS OTPs are slow, get filtered and cost money on every attempt. Many users in India are on WhatsApp all day, so an OTP delivered there is seen quickly and is hard to miss.

The Chatnoxe API sends authentication and transactional messages — login codes, signup verification, order confirmations, payment and dispatch alerts — through Meta-approved templates, and reports delivery status back to your system by webhook.

You pay for the platform plus Meta’s authentication-message charge per message. We quote against your expected monthly OTP volume.

Good to know: OTP delivery depends on the user having WhatsApp and on Meta’s template rules. Critical logins should keep a fallback method.

WhatsApp OTP & Authentication API — FAQs

Can I send OTP codes over WhatsApp in India?

Yes, through the official API using an authentication template approved by Meta. The code sits inside the template, and the user can copy it in one tap.

Is WhatsApp OTP cheaper than SMS?

It depends on volume and Meta’s current charges. We give you a per-message estimate so you can compare with your current SMS cost.

What if the user is not on WhatsApp?

The message will not be delivered. We recommend an SMS or email fallback for critical flows.

Can you integrate it with our website or app?

Yes. We provide an API and webhooks, and our developers can do the integration with your Node, PHP, Python, Java or ERPNext stack.

Can I also send order and payment updates?

Yes, through utility templates for order confirmation, invoice, payment reminder and dispatch alerts.
