# How Can I Resend an OTP if Users Don’t Receive It After the First Few Attempts?

With **SMSGatewayCenter**’s I**[ntegrated OTP SMS](https://www.smsgatewaycenter.com/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**](https://www.smsgatewaycenter.com/developer-api/generate-otp/) 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](https://www.smsgatewaycenter.com/blog/kb/where-can-i-find-and-download-integrated-otp-sms-logs/)**), so you can troubleshoot effectively. Ready to keep your authentication flow smooth? Add the **renew** parameter to your API today and empower your users with seamless OTP resends!
