#### Checking Debug Logs
Review the WooCommerce debug logs (located in `woocommerce/logs/`) for any errors or warnings. This can provide valuable insights into potential problems.

Troubleshooting Common Issues
- “Invalid API Credentials”: Double-check that you’ve entered the correct email address for your Business Sandbox account in the WooCommerce PayPal settings.
- “Payment Failed”: Refer to the debug logs and PayPal developer documentation for specific error codes and resolutions. Ensure you’re using valid test credit card numbers.

Moving to Production
Once you’ve thoroughly tested your PayPal WooCommerce integration in the sandbox environment, you can switch to the live (production) environment.
1. Disable “PayPal Sandbox” in the WooCommerce PayPal settings.
2. Enter your live PayPal email address and API credentials (if required for your setup).
3. Run a few small test transactions with a real credit card to ensure everything is working as expected in the live environment before fully launching your store.
4. Monitor your transactions and debug logs closely for any issues.

Testing your PayPal WooCommerce integration is a vital step in launching a successful online store. By following the steps outlined in this guide, you can create a safe and reliable payment experience for your customers, minimizing potential problems and maximizing your sales.
