Retrieve value from open external API - visual studio - javascript - AJAX

I would really appreciate some advice, I'm trying to retrieve information from an open API for the first time.

The API details are here,

https://data.police.uk/docs/method/neighbourhood-locate/

I want to retrieve the 'force' and 'neighbourhood' values and save them into variables, I want to save them as variables as I'm then calling googlemaps to display the KML map. I managed to get quite far on other sections of my code, such as geocoding a user inputted address and retrieving the Long/Lat, but I am now struggling to send the long/lat to the exteal API and save the response.

I've hardcoded the long/lat into the below URL for this advice request, I think I'm getting a response from the API but failing to capture the values into my variables. The debugger shows the following response, {"force":"metropolitan","neighbourhood":"00BK17N"}, below is my code,

        var ForceId; //retued from the API
        var Neighbourhood; //retued from the API
        accessURL = "https://data.police.uk/api/locate-neighbourhood?q=51.500617,-0.124629"
        //Use the zip code and retu all market ids in area.
        $.ajax({
            type: "GET",
            contentType: "application/json; charset=utf-8",
            url: accessURL,
            dataType: 'jsonp',
            success: function (data) {


                ForceId.push(val.force);
                Neighbourhood.push(val.Neighbourhood)

                console.log(ForceId);
                console.log(Neighbourhood);

            }})
