Pre Auth

POST 
/public/sdk/v1/preauth

The /preauth endpoint is used for two things:

  • Determine if card number is enrolled for 3-D Secure v2. This can be used to decide if you should fall back to using 3-D Secure v1.0.2
  • 3DSMethod invocation information

If the card number is enrolled for 3-D Secure v2 a valid response will be returned. Otherwise an messageType "Erro" will be returned.

  • This endpoint relies on cached data and should respond “instantly”.
  • The cached data is refreshed every few hours and should always be up to date.

The threeDSServerTransID expires after 80 seconds.
