Action Scheduler to Hit External PHP File

Here’s a couple of forums with answers.
This one suggests addressing it to curl

I’ve run CRON jobs where the php file was called from one server across domains to another server which contained the script that would update a database table.

Of course, that page had to be protected by a username and password.

Cron <wp12516289@vwp3740> /is/htdocs/wp12263389_VXR92NWLJ9/www/mytargetwebsite.de/sql-update-database.sh

the CRON file on the first server sat in the folder structure outside the public html folders as this example:

**/bin/sh**: 
/is/htdocs/wp12263389_VXR92NWLJ9/www/mytargetwebsite.de/sql-update-database.sh
``

Here’s a pretty comprehensive summary of useful crontab commands:
