Before testing 3DS in sandbox there is some configuration required:
Configure 3DS for each of the schemes to test with against the primary card connector. Use
any random data for the Acquirer BIN and other fields.
Ensure Flow rules do not skip 3DS for specific test scenarios
The 3DS provider uses different card numbers to simulate various responses. Use the following test cards.
Each connector handles sandbox testing and test PANs differently, so it may or may not be
possible to use these PANs to test end-to-end in sandbox.
Using the card simulator to test
3DS independent of your payment service provider’s sandbox is recommended.
