I'm trying to figure out how to do a batch transfer of domains into my Resellone account.

I'm not using the API. I'm trying to do this in the existing interface. The only thing I see that might come close to being a way to do a batch transfer is the "Place Bulk Order Manually" link on the main page.

If you go to that link, you can upload a text file with a list of domains, username and password. But once this is uploaded, and you submit the list, it tries to REGISTER the domains, rather than TRANSFER the domains.

Am I totally missing something here, or what? How can I do a batch transfer?

Batch transfers will be available through the API as soon as the developement team has completed the documentation.
