> Maybe this will help: Backblaze started using Stripe a long time ago (gosh, maybe 10 years ago?) and used a very specific set of original Stripe APIs. When some banking laws in some countries (specifically India at the time) changed a couple years ago, Backblaze looked into enabling 3D secure and SEPA and found out Backblaze was using the "1.0" version of the APIs that DID NOT support 3D secure and SEPA, and that to use 3D secure and some other features like SEPA then Backblaze had to "port" all of the Backblaze billing code to use the new "2.0" version of the APIs. So that project was kicked off, a programmer on the Backblaze billing team began working on that. But it probably should be finished by now. Or close.

That seems plausible given how archaic their administration system looks like.
