With SMSGatewayCenter’s Integrated OTP SMS service, resending an OTP is quick and hassle-free, ensuring your users never get stuck during authentication. If a user doesn’t receive the OTP due to network issues or other delays, you can trigger a resend using our Generate OTP API with a simple parameter tweak.
How to Resend an OTP: #
The key lies in the optional renew parameter in the Generate OTP API:
- Default Setting: By default, renew is set to false, meaning the system generates a new OTP only for the first request and doesn’t resend automatically.
- Resend Option: To regenerate or resend the OTP to the same recipient, set renew=true in your API call. This instructs the system to either create a fresh OTP or resend the existing one, depending on your configuration, and deliver it to the user’s phone number instantly.
Example Usage: #
- Initial OTP Request: GET /generate-otp?mobile=919876543210 (renew defaults to false).
- Resend OTP Request: GET /generate-otp?mobile=919876543210&renew=true.
Why It’s Useful: #
- User Convenience: Gives users another chance to receive the OTP without frustration.
- Reliable Delivery: Leverages our 100% delivery guarantee, including SMS and voice backup options.
- Flexible Control: You decide when to resend based on your app’s logic or user feedback.
Pro Tip: #
If users frequently report non-delivery, check their network status or ensure the number is correct. Our system logs all OTP attempts (see OTP Logs), so you can troubleshoot effectively.
