jQuery posts null instead of JSON to ASP.NET Web API

Question

I can\'t seem to get this to work... I have some jQuery like this on the client:

$.ajax({
    type: \"POST\",
    url: \"api/report/reportexists/\",
    data

jQuery.ajax() by default sets the contentType to be application/x-www-form-urlencoded. You could send the request in application/json instead. Also, you should send your data as a string and it will get model bind to the report parameter for your post method:

$.ajax({
    type: "POST",
    url: "api/report/reportexists/",
    contentType:  "application/json",
    data: JSON.stringify(reportpath),
    success: function(exists) {
        if (exists) {
            fileExists = true;
        } else {
            fileExists = false;
        }
    }
});
