External 3DS / MPI

External 3-D Secure authentication

You can use an external 3-D Secure provider (also known as an external MPI) to handle customer authentication and have finby process the payment.

How it works:

1. Your external 3DS provider handles customer authentication and returns the authentication result.
2. Your system submits the payment request to finby, including the resulting 3DS authentication data.
3. finby uses the supplied data when requesting authorisation and returns the payment status.

Further details

• Requires prior enablement by finby.
• For technical details, see the Server 2 Server 3DS data section.
