404 error when using browser url

by Elliott Lovell.  

I am attempting to view the json response in a browser for the custom service that I created on my moodlecloud site.

I have four functions, and I am trying to return the calendar events.

The url is formatted as follows:

https://mysite.moodlecloud.com/moodle/webservice/rest/server.php?wstoken=XXXXXXXXXXXX&wsfunction=core_calendar_get_calendar_events&moodlewsrestformat=json

The token I am using is specific to my _admin user. Do I need to append anything else to the end of the url? As is, this URL takes me to the Moodle 404 page.
