User verification should be fast, secure, and hassle-free. Eazy OTP offers a powerful WhatsApp OTP India solution that enables businesses to send one-time passwords directly through WhatsApp. From user registration and login verification to password resets and transaction authentication, our API ensures every OTP reaches your customers quickly and securely. Built for startups, enterprises, fintech, eCommerce, healthcare, and SaaS businesses, our platform provides reliable OTP delivery with easy integration and enterprise-grade performance.
A WhatsApp OTP replaces the SMS inbox with the chat app your customer already uses. The code arrives as a WhatsApp authentication message from a business account, sent with a pre-approved template, so the customer sees who it is from and copies the code back into your app.
With EazyOTP your backend never builds the message: it sends the phone number and gets back the result.
