While I haven't tried to "Import External Data" Supertote recently, I know that a few years back Brisnet was shutting down frequent pingers of Supertote. I am fairly sure that one could, at least initially, import the tote, but whether or not you would be allowed to continuously ping the server I have serious doubts.
There are other online totes that are probably much more accommodating. This one will work for sure, or was working a short time ago:
