Hi,
Last week end I made the re-factoring of the Klarna plugin, using the new HikaShop payment interface.
Unfortunately, when I wanted to test it, I saw that the "beta" platform is no more accessible.The official SDK have some wrong links (urls) that we have to fix and we are waiting for some new access in order to be capable of test our new implementation.
