Message Central has launched V3 of its OTP SMS verification APIs. There have been many updates including an introduction of fallback mechanism for an OTP verification code.

What is Fallback Mechanism?

A fallback mechanism is having a backup in case the primary channel defaults. In case of OTP SMS verification, the same will be sending an OTP/code via a primary channel and if the same fails to deliver, using other channels to deliver OTP SMS to the user.

OTP SMS verification is a very critical use case for any business since this is either: -

1. The first interaction between a user and business in the form of onboarding OR
2. Crucial stage interaction like payments and checkout

Thus, it becomes very important for a business to ensure that the verification code/ OTP gets delivered to the user. This is where the fallback mechanism for OTP verification comes in.

How Does Fallback Mechanism Works for OTP Verification?

The OTP verification fallback mechanism with Message Central works on several channels including: -

1. SMS
2. WhatsApp
3. RCS

This versatility also ensures that users can receive OTPs through their preferred communication method and there are no failure cases of OTP delivery.

You’ll be able to check the real-time analytics with the SMS dashboard provided by Message Central.
