Can you add headers to getJSON in jQuery?

$.getJSON is a shorthand for

$.ajax({    dataType: "json",    url: url,    data: data,    success: success});

So you can simply use it directly like

$.ajax({    beforeSend: function(request) {        request.setRequestHeader("X-Mashape-Key", 'key_here');    },    dataType: "json",    url: settings.apiPath + settings.username + '/boards/',    success: function(data) {        //Your code    }});

using $.ajax() would have been better, as $.getJSON is shorthand function, if you cant use $.ajax(), you can use $.ajaxSetup to set headers, as:

$.ajaxSetup({  headers : {       'X-Mashape-Key' : 'key_here'  }});$.getJSON(settings.apiPath + settings.username + '/boards/', function (data) { ...

But note that it sets headers for future Ajax requests.

Since getJSON is a shortcut notation for $.ajax() why not use that

$.ajax({  dataType: "json",  url: url,  data: data,  success: success});

ajax() provides a hook called which you can specify by beforeSend: function(jqXHR, settings)

The hook allows one to add custom headers to outgoing AJAX request ... I think unlike $.ajaxSetup ... you do not have to worry about unsetting after using it
