When you host your application and need to update the callback URL for a payment gateway (or any other external service), you generally need to provide the fully qualified URL that points to your hosted environment. Here’s a step-by-step approach to resolve the issue:

Determine the Full URL:
- After hosting, the callback URL should be the complete URL of your hosted application. For example, if your application is hosted on https://example.com, your callback URL would be https://example.com/frm/Response.aspx.
Update the Callback URL:
- Make sure to replace the localhost URL with the full URL of your hosted application. For example:
```
requestToGateway.callbackUrl = "https://example.com/frm/Response.aspx";
```
- Check the Payment Gateway Configuration:
  - Ensure that the payment gateway's configuration allows the new callback URL. Some payment gateways might require you to register or whitelist callback URLs in their settings.
- Verify SSL/TLS Certificates:
  - If your hosted application is running over HTTPS, ensure that your SSL/TLS certificates are correctly configured and valid. Payment gateways typically require secure (HTTPS) callback URLs.
- Test the Callback URL:
  - Manually test the callback URL in your browser or using tools like Postman to ensure that it is accessible and correctly responds.
- Update Any Relative Paths:
  - Ensure that any relative paths in your application are correctly resolved to the full URL structure.
```
// Update the callback URL to the full URL after hosting
requestToGateway.callbackUrl = "https://example.com/frm/Response.aspx";
```
    Additional Considerations:
  - CORS (Cross-Origin Resource Sharing): Ensure that CORS settings on your server allow requests from the payment gateway if necessary.
  - Firewall and Security Rules: Ensure that your hosting environment’s firewall or security settings allow incoming requests to your callback URL.
  - By providing the fully qualified URL, you ensure that the payment gateway can successfully communicate with your hosted application.
