Simulates a 3DS authentication request from the payment network as if it came from an ACS. If you're configured for 3DS Customer Decisioning, simulating authentications requires your customer decisioning endpoint to be set up properly (respond with a valid JSON). If the authentication decision is to challenge, ensure that the account holder associated with the card transaction has a valid phone number configured to receive the OTP code via SMS.
