Auto-Resend on WhatsApp or RCS When an OTP SMS doesn't arrive, users leave. SMSGatewayCenter's Multi-Channel Fallback retries the same message on the next channel automatically: SMS, then WhatsApp, then RCS, in the order you set. One approved template per channel, with variable mapping so the same OTP appears everywhere. Fail over on any error, or only on the error codes you pick (for example DND or timeout). Every attempt shows in Message History, plus Failover Analytics.

With the SMSGatewayCenter OTP API you make two calls. First, sendMethod=generate creates the OTP and sends it by SMS, with the code length, type (numeric, alpha, alphanumeric) and expiry (default 300 seconds) set by you. Second, sendMethod=verify checks the code your user typed and returns success or failure. In India, OTP SMS needs an approved sender ID and a DLT-registered template.

Now It Verifies Users Too Every Indian knows the one-ring missed call. Turns out it can verify your users' phone numbers too. How SMSGatewayCenter's Missed Call OTP works: your app shows the user a missed call number. The user dials it, and the call disconnects automatically at no cost to the user. We send the caller's number to your callback URL, and you mark the number verified. No code to type, and it works on any phone that can make a call. Needs a dedicated missed call number and our Missed Call OTP API.
