Download Data from External Source

Good Afternoon

I'm trying to build an asset database in PowerApps to automate a compliance requirement. Currently, we use an external database to manage the tools. 

And while it's easy enough to download the basic data for the tools, the website also contains images and documents. The pictures are a nice to have but the documents are a compliance requirement.

So my question is, once built, can I populate the underlying data from this external source and can Power Automate pull down the documents and images as well? - Or will I have to manually download each document and upload into our local system?

Thanks,

Christine
