Automating Secure Data Uploads from Rally to Dovetail

hi team! I’m exploring automating data between our research CRM (Rally) and Dovetail. Rally’s API gives me access to interview recordings, and I’d like to upload those automatically to Dovetail. From your docs, it looks like the /api/v1/data/import/file endpoint only supports importing via a public URL. I might be misunderstanding how that works, but it seems risky from a security standpoint, especially since for our purposes these recordings can include customer data. Is there a secure way to automate uploads without making files publicly accessible? And if not, is support for private or authenticated uploads something on your roadmap?
