eventSources url

[whycosys]

The code below never results in any events being displayed.
I've only just began with your very nice looking calendar. Would like to continue...
I've sent the data so many ways and never anything new. I can tell the url is being read from the server php.

Would love to get this working.... TIA

let ec = new EventCalendar(document.getElementById('CalendarTab'), {
view: 'timeGridWeek',
headerToolbar: {
start: 'prev,next today',
center: 'title',
end: 'dayGridMonth,timeGridWeek,timeGridDay,listWeek'
},
eventSources: [
{"url":"/ye/api.php?apikey=1234&apicmd=events"}
]
});
