Our payment simulator page encountered an error when trying to request a checkout session:

How to Fix This:

1. Open demo.php in a text editor.
2. Locate variables $apiKey and $apiSecret at the top of the file (lines 14 & 15).
3. Replace the mock credentials with the active API keys generated inside your merchant dashboard.
4. Refresh this page to run the checkout redirect automatically.
