Web-Based Card Test: A Comprehensive Guide

What is an online credit card test?

It is a controlled check of your payment flow using sandbox credentials and test card numbers, so you can confirm that your checkout behaves correctly without moving real money.

Which card numbers should you use?

Use the test card numbers published by your payment processor for each scenario, such as successful authorization, decline, or expired card. Never use real customer card data in a test environment.

Is it safe to test with real card data?

No. Real cardholder data should stay in production systems that meet PCI DSS requirements; testing should rely on sandbox data and tokenized references.
