I use the following code in my PHP script to automatically download the latest version of WordPress...
$wordpress_zip_file_url = 'https://wordpress.org/latest.zip';
file_put_contents("wordpress.zip", file_get_contents($wordpress_zip_file_url));
Does this work for plugins the same way? For example, I'd like to automatically download the latest backupwordpress plugin version --> https://wordpress.org/plugins/backupwordpress/
Is there a generic link to download the latest version of a plugin?
https://downloads.wordpress.org/plugin/{plugin-name}.latest-stable.zip
The structure should be the same for all WordPress.org plugins and the link you're looking for is:
https://downloads.wordpress.org/plugin/backupwordpress.latest-stable.zip.
You can see an example here on how this might be used.
To update plugins through WP-CLI:
wp plugin update backupwordpress
latest-stable link existed. This should be the answer.

{slug}.latest.zip and {slug}.trunk.zip but that didn't work ;-)
Sounds like what you are really after is wp-cli which will let you write shell script that automate such tasks.
When you're doing a plugin update, in the process where it shows you all the steps, you can also see the plugin download url. Usually the last version can be always found there.
latest.zipoption for plugins and can't immediately see one; you might need to hook into the Wordpress plugin management system to grab the URL. It'll be possible, but you might need to trawl through how core does it to work it out.
