- Implement retry logic for network failures
- Provide clear error messages to users
3. **Testing**
- Always test with sandbox environment first

- Verify callback handling before production
Common Issues
| Issue | Solution | |-------|----------| | CheckValue validation fails | Verify HashKey/HashIV and parameter order | | Callback not received | Check NotifyURL is accessible (port 80/443) | | Encryption fails | Ensure input is properly URL-encoded first | | Refund rejected | Check if transaction is within refund period |
