I try to get some data from one of those APIs out there..
What I can see in the documentation, this should be written something like the code below.
I got the data back in Postman, using the URL (with my own api Key), but in google chrome I just 'error ' got Unexpected token : and {"StatusCode":0," - btw, not sure what I should place in the headers..?

Any one that could guide me here?

Thanks in advance!

1. 
   
2. $(function(){
3.     $.ajax({
4.         async: true,
5.         dataType: 'json',
6.         crossDomain: true,
7.         url: "https://api.sl.se/api2/realtimedeparturesV4.json?key=xxxxx&siteid=9192&timewindow=60?callback=?",
8.         method: "GET",
9.         headers: {
10.             "Accept": "application/jsonp;odata=verbose", 
11.         },
12.     })
13. 
    
14.     .done(successFunction)
15.     .fail(failFunction)
16. 
    
17.     function successFunction(data){
18.         console.log('ok..')
19.     }
20.     function failFunction(request, textStatus, errorThrown) {
21.         console.log('not ok.. ');
22.     }
23. });
