The ajax call needs a token that expires frequently. There is no external process to periodically fetch a new token so I'm stuck. What I'd like to happen in this scenario when it's expired is: 1.Function fails 2.Fail case executes a new call to get a new token 3. Original Ajax call tries again, this time with a good token. Below is what I have:

$.ajax({
    method: "GET",
    url: myUrl,
    headers: { "Authorization": "Bearer " myToken}
    })
    .done(function(data, statusText, xhr){
        //All good here
    })
    .fail(function (xhr, response){
        if(xhr.status == 401){

             //Here is where I'm looking to find a solution
             //First get new token here ex. function getToken()
             //Next retry above function


        }
    });
