💳 Test Cards

This page lists test card numbers for simulating payment results during UseePay integration. Use these cards to test success and failure flows in sandbox environments.

⚠️ Note: These test cards only work in sandbox (test) mode and will not trigger real transactions.

📋 Card List

Card Number	Result
`4242 4242 4242 4242`	✅ Success
`4024 0238 5274 3737`	❌ Failed

✅ Success Scenario

Use the card 4242 4242 4242 4242

The transaction will be processed as successful

You can verify webhook callbacks, success pages, and subscription activation

❌ Failure Scenario

Use any 3-digit CVV (e.g., 123)

Name and postal code can be arbitrary unless required by your form
