How to integrate Samsung In App Purchases library?

I have registered Samsung Seller Portal Developer account, company type, everything is verified, added even DUNS:

but when I try to download the IAP library from https://developer.samsung.com/iap/release-note.html:

it redirects me to the following page where I can’t do anything at all… what should I enter there? it doesn’t accept anything, it seems not related to Samsung Seller Portal developer account.

seems I had just to create another account before on this website as well

Hi @android_dev ,

That’s correct, you need to also register to Samsung Developers Portal in order to download the SDK.
