How to set the cron job notifications in Amelia Booking?

I installed WP Control Plugin, created the schedule per the faq and created the event. WP Control insists there's a syntax error in the lines provided by amelia. I inserted the correct domain.

All 4 prompt a syntax error in WP Control php event - (without <?php tag) as instructed:

*/15 * * * * https://carwashquickies.com/wp-admin/admin-ajax.php?action=wpamelia_api&call=/notifications/scheduled/send

If that doesn't work, please try with these as well:

*/15 * * * * wget -q -O - "https://www.carwashquickies.com/wp-admin/admin-ajax.php?action=wpamelia_api&call=/notifications/scheduled/send"

*/15 * * * * /usr/local/bin/php ~/public_html/wp-cron.php --action='wpamelia_api' --call='/notifications/scheduled/send'

GET 'https://carwashquickies.com/wp-admin/admin-ajax.php?action=wpamelia_api&call=/notifications/scheduled/send' > /dev/null

Error:

"PHP Code
 Line 1: syntax error, unexpected '*', expecting end of file"

Use this format in the cron job: 

file_get_contents("https://yourwebsite.com/wp-admin/admin-ajax.php?action=wpamelia_api&call=/notifications/scheduled/send");

it works for me.

Plugin accepted the code - looking good, thank you!
