An SMS OTP verification API confirms that a person has access to the mobile number they gave you, by sending a one-time password and checking what they type back. It is one of the most common checks on the internet, which is exactly why the details matter: small design choices decide whether users breeze through or abandon the flow. This section covers how to get the most from an SMS OTP verification API.
Short numeric codes are easiest to type on a phone. Give each code a short expiry, typically a few minutes, so an intercepted or forgotten code quickly becomes useless. Allow a resend, but only after a short wait, and invalidate the previous code when a new one is sent.
An SMS OTP verification API can be misused to send floods of messages, which costs money and annoys the owners of those numbers. Limit how many codes can be requested per number and per device or IP address in a given period, and limit how many wrong attempts are allowed before a code is locked. These limits protect both your budget and your users.
Businesses sending commercial SMS in India must register their sender IDs and message templates on the Distributed Ledger Technology platform set up under TRAI's regulations. OTP messages are no exception, so make sure the template your SMS OTP verification API sends is registered, otherwise messages may not be delivered. TRAI publishes its rules on the TRAI website.
Sign-up and login, confirming a phone number before it is used for alerts, approving a sensitive change such as a new payout account, and confirming a transaction are all common uses. In each case the SMS OTP verification API proves possession of the number at that moment.
An OTP proves that someone could receive SMS on that number when the code was sent. It does not prove who owns the number, so for higher-risk decisions combine the SMS OTP verification API with identity checks rather than relying on the OTP alone.
