I'll respond to everyone's comments here.

robarr: These scripts are other ways to use Amazon's Send To Kindle capability. Send To Kindle does not accept KFX format files.

kyteflyer: See above, Send To Kindle does not accept KFX format files.

thomsen: I am aware of the capability of using Finder to transfer the files. However, it requires the iPad be plugged into the Mac using USB. I have not found any means of automating this. You have to drag and drop files. Your second option of using cloud storage doesn't work with KFX files. If I attempt to open a KFX file stored in iCloud, for example, on my iPad, it does not properly load into the Kindle app.

My point with this thread is to see if anyone knows a method of automating the transfer of KFX files from my Mac to my iPad/iPhone.

Imazing is still the best I have found since at least it uses a wireless connection. However, I still can't find a way to script it--it requires using drag and drop. I may try doing this with Keyboard Maestro, which has that capability, although most advise against using it because mouse targets are inconsistent.

Ideally, I would have a command line script in macOS and I could access it via ssh from my iPad to initiate transfer of a file from the mac's file system.
