ASP.net MVC Controller receiving null array when sending from Ajax

I've been at this for what seems like days now. This should be so simple. Why isn't this working? My URL looks like this:

https://example.com/photos/gallery/c15905d7-8216-4e81-ac15-2fafd10b49e8/80515cad-070a-4d61-a7e3-f2dbb1968c9d

I want to send c15905d7-8216-4e81-ac15-2fafd10b49e8 & 80515cad-070a-4d61-a7e3-f2dbb1968c9d to my controller.

Here is the last thing I've tried (of 20748 attempts):

function setViewed() {
    var pathArray = window.location.pathname.split('/');

    $.ajax({
        type: "PUT",
        url: '/api/Customers/',
        data: { 'pathArray': pathArray },
        dataType: "json",
        traditional: true,
        success: function (response) {
            alert(response.msg);
        }
    });
}

Controller:

[HttpPut]
public IHttpActionResult SeenIt(List<String> pathArray)
{

    // Don't update if it's the client looking at a customer's gallery:
    if (pathArray[3] == User.Identity.GetUserId()){
        return Json(new
        {
            msg = String.Format("ClientID: {0} | CustomerID: {1}", pathArray[3], pathArray[4])
        });
    }

    var customer = db.Customers.FirstOrDefault(c => c.CustomerID == Guid.Parse(pathArray[4]));
    customer.Accessed = true;

    db.SaveChanges();
    return Json(new
    {
        msg = String.Format("ClientID: {0} | CustomerID: {1}", pathArray[3], pathArray[4])
    });
}

My array is always null. Is there a better/easier/more efficient way to do this? One that works? Thanks!

I know this is an old post but for anyone using ajax to post versus straight JS I found that adding this helped:

contentType: "application/json; charset=utf-8",

Option 1

In your ajax call, no need to wrap the list string with {}. Simply use;

data:pathArray

Option 2

Make a class that would serve as the model where the properties would be bound.

public class ReceiveModel{
   public List<string> pathArray {get;set;}
}

Then in your controller

public IHttpActionResult SeenIt(ReceiveModel model)
{
   ...
}
