How to fill inallowAuthentication? Or how to control whether an international card transaction requires 3DS?

You can use the allowAuthentication parameter to control whether 3DS should be performed for an international card transaction.

  • Sending true means you want this transaction to perform 3DS, and our system will process accordingly.
  • Sending false means you do not want 3DS, but our system will decide based on your merchant 3DS settings (Optional-Authentication or Must Authentication) and real-time risk control judgment. This means 3DS may still be performed.
