How can I find out if a transaction was performed with Secure v1 or v2?

Along with the platform release in July we have enhanced our transaction overview details. Individual transactions accessible now contain detailed information on which flow (legacy 3DS v1  or 3Dsv2) was applied. More information can be found in our notes for Release 04.133 in the Backoffice via Support > Platform Releases > Release 04.133

In addition to that we have added the new parameter VERSION_3DS to our electronic reporting tool.

The possible values for VERSION_3DS are

V1  (for 3DS v1)
V2C (for 3DS v2 challenge flow)
V2F (for 3DS v2 frictionless flow) 

To add this parameter to your transaction file downloads, follow the instructions as shown in this video:
