I am creating a crontab to execute a GET server action which is protected by a username and password based security provider. The crontab will execute a curl to do this.
What curl syntax do I need for specifying the username and password?
curl http://test.workshop-angel.com/dmxConnect/api/crontab/crontab_test.php WHAT_OPTIONS_HERE?
If being called from another server action, I would be calling crontab_test.php like this:
Actually, what would be even better is if I can just run the PHP file locally from on the server rather than via the HTTP path, so to say something like:
php /var/www/html/dmxConnect/api/some_file.php WHAT_LOGIN_OPTIONS_HERE?
Is this calling an external providers API? Typically they will have documentation on how to authenticate, and usually a username/password is applied in the header as
Authorization | Bearer(or other) apikey/username:password (encored) or other…
No, it is calling a Wappler Server Action… hence I need to know the Wappler way!

One way would be with the GET vars like this:
curl http://test.workshop-angel.com/dmxConnect/api/crontab/crontab_test.php?username=abc&password=123
