How to test card payments

You can simulate multiple card payment scenarios in the sandbox using the test cards provided by Antom:

• Initiate a successful payment based on card brand or country/region.
• Simulate a failed payment due to payment method failure or invalid data.
• Simulate 3D secure authentication and 3D exemption scenarios.

User experience

Simulate a successful payment

Use the following test card numbers in the sandbox and input any value for CVC (3-digit number), postal code, expiration date, and the first two digits of the payment password.

Simulate a failed payment

Use the following test card numbers, invalid data, or risk control failure simmulation trigger to simulate a failed payment.

Test card number for failed payments

Invalid data

Use any invalid data to test error scenarios caused by incorrect inputs, for example:

• invalid_expiry_month: use an invalid month, such as 13.
• invalid_cvc: use a two-digit cvv number, such as 99.

Fail due to risk control

Specify paymentAmount.value in the pay API as 11 to simulate a failed payment due to risk control.

3D secure authentication

3D challenge

Specify is3DSAuthentication in the pay API as true to initiate a 3D secure authentication.

3D exemption

Use the specific card number 4035501000000008 to trigger the 3D exemption.
