# Step-by-Step Guide to Using SMSGatewayCenter Verify OTP API

Looking to secure your app with SMSGatewayCenter’s **[Verify OTP API](https://www.smsgatewaycenter.com/developer-api/verify-otp/)**? This tool lets you confirm one-time passwords for user authentication, ensuring a safe experience. Let’s dive into the process!

**Integration Steps**

1. **Access Your Credentials**: Log in to your SMSGatewayCenter account and find your `userid` and `password` under the API section. Make sure your `senderId` is DLT-registered for compliance.
2. **Understand Required Parameters**: Prepare to use `userid`, `password`, `mobile` (e.g., `919876543210`), `otp` (the code entered by the user), and `sendMethod=verify`.
3. **Send Verification Request**: Use a tool like cURL or Postman to submit these parameters. While the exact endpoint isn’t listed here, it typically follows our OTP API format—check your account dashboard or contact support for the URL.
4. **Check the Response**: Look for `status: success` or `status: error` with a `reason` (e.g., `Invalid OTP`) to confirm verification.
5. **Integrate into Your App**: Add logic to handle successful or failed verifications, updating your user interface accordingly.

**Best Practices**

- Verify OTPs within the expiry window set during generation.
- Ensure DLT-compliant templates for initial OTP sends.
- Test thoroughly before going live.
