Testing Your Integration¶

This guide will help you test your UnelmaPay integration before going live.

Testing Environment¶

Development Environment¶

• URL: https://dev.unelmapay.com/sci/form
• Purpose: Initial testing and development
• Features:
• Test payments (no real money involved)
• Immediate feedback
• Test merchant accounts available

Testing IPN Callbacks¶

1. Set up your IPN handler
2. Ensure it's accessible via HTTPS
3. Enable detailed logging

4. Handle duplicate notifications

5. Test IPN Endpoint

   curl -X POST https://your-server.com/ipn_handler.php \
     -d "total=10.00" \
     -d "date=20230809" \
     -d "id_transfer=TEST_123" \
     -d "hash=TEST_HASH" \
     -d "custom=ORDER_123" \
     -d "item_name=Test+Product" \
     -d "currency=debit_base"
   

Common Test Scenarios¶

Successful Payment¶

1. Submit payment form with valid test card
2. Verify IPN received with status=completed
3. Check order status in your system

Failed Payment¶

1. Use failing test card (4000 0000 0000 0002)
2. Verify proper error handling
3. Check IPN for failure notification

IPN Verification¶

1. Send test IPN to your endpoint
2. Verify hash calculation
3. Check database updates

Debugging Tips¶

1. Check Logs

   tail -f /path/to/your/ipn_log.txt
   

2. Verify Hash

   $hash = strtoupper(md5($total . ':' . $merchantPassword . ':' . $date . ':' . $idTransfer));
   

3. Test Locally

4. Use ngrok for local testing
5. Forward requests to localhost
6. Inspect incoming requests

Going Live¶

Before going live: 1. Test all payment scenarios 2. Verify IPN handling 3. Remove test credentials 4. Enable production API keys 5. Monitor transactions closely
