We have updated sandbox testing for Online Payments to use a dedicated set of test cards.
This affects all Online Payments integrations tested with sandbox merchant accounts.
What changed:
- Sandbox testing now relies on predefined test card numbers.
- The test set covers successful payments, payment failures, and 3D Secure scenarios.
Migration note: update your QA flows to use the documented test cards and expected outcomes.
See Testing online payments for setup steps, card numbers, and expected behavior.
