 Businesses can use the WhatsApp Business API or Airtel’s network-embedded Hyperlocal Marketing solution to send OTPs securely. It is a convenient and reliable method, with benefits for both companies and consumers.
Differences between SMS OTP and WhatsApp OTP
 When it comes to WhatsApp OTP vs SMS OTP, there are key differences between the two methods.
 SMS OTPs are sent over a cellular network. This network can be vulnerable to interception and other attacks. WhatsApp OTPs are sent over the internet and are end-to-end encrypted. Only the sender and receiver can see the messages.
 Another difference between SMS OTPs and WhatsApp OTPs is convenience. SMS OTPs can be sent to any phone number, even if the user does not have WhatsApp installed. However, WhatsApp OTPs can only be sent to users who have WhatsApp installed.Â
There are other features unique to WhatsApp OTPs that are not available on SMS. For example, rich media content, such as images and videos. This feature is useful for businesses that want to send personalised OTP messages to their customers.Â
