Amazingly, this was asked in 2018. But time has passed and maybe there’s a different answer.
Specifically, I’d like to go to a URL, enter a username and password, navigate to another page, and download a text file that would be imported into Panorama. I’m guessing for part/most of the work, I could use one of those “sequence copiers” that records keystrokes and mouse movement. If that “sequencer” was AppleScript aware, I could let it do fill/grab when triggered by AppleScript from within Panorama. For those who pull data from 3rd party webpages, how do you do it now?
