If you're processing a payment that fails through 3D Secure, and you immediately see Authorised or Refused, this might be because required fields are missing in your request, such as the browserInfo and the billingAddress objects.

You should also check your dynamic 3Ds rules to ensure they are not preventing 3DS authentication.
