These cases are essential for verifying your integration logic, notification handling, and payment flow resilience.

Test Card Processor

The test cases described below will only work with the special payment interfaces: Test Card Processor (for credit cards) and Test E-Wallet (for APMs).

Payment Details

Field	Value
Card Number	Any valid card number
Card Holder	First name and last name
Card Expires	Any future date
Currency	Any available
Amount	See `Sale Amount` and `Payout Amount` tables below
CVV	See `Sale CVV` table below

Sale CVV

Note: All AMEX cards have a 4-digit CVV, whereas the test cases are triggered with a specific 3-digit CVV. To use the same test cases with AMEX cards, please add 1 as the fourth digit to the CVVs listed below.

Example: For the approved non-3DS scenario with AMEX, change 568 to 5681.

CVV	Result	Description
568	Approved	Standard approval (if `transaction_type = authorization` > status: `authorized`)
588	Declined (Timeout)	Along with amount 713, transaction is created with status: `PENDING_ASYNC`, then transitions to DECLINED with the error message “Transaction timed out”
333, 300	3DSecure Redirect	Redirects to a 3DS simulation page (with "approve" and "decline" buttons)
000	Declined	Standard decline
333 + Amount 334	Duplicate Notifications (Status Change)	Once redirected to 3DSecure simulation, clicking “Approve” causes duplicate notifications reflecting different final statuses (final status change scenario)
333 + Amount 335	Duplicate Notifications (Amount Mismatch)	Causes duplicate notifications reflecting final APPROVED statuses and amount change (amount mismatch scenario)
353	Partial Approved	Non-3D partial approved (partial confirmation scenario)
444	Error	Server Error
454 + Amount 498	Partial Approved (Amount Change at PSP)	Transaction is created with status: `PENDING_ASYNC`, redirects to a page with "Approve" and "Decline" buttons. If “Approve” is chosen, the user must confirm a partial approval of amount 400 instead of 498

801	Declined	Insufficient Funds
900	Declined	Card has been lost
901	Declined	Card has been stolen
