    To make ajax work in wordpress you need to instruct wordpress about what it should do when he receive your ajax request.

    To do so you need to use something like this:

    add_action( 'wp_ajax_create_chapter', 'create_chapter' );

    if you need that to work for non-logged in user you need this in addition:

    add_action( 'wp_ajax_nopriv_create_chapter', 'create_chapter' );

    the "nopriv" just means it’s open for everyone. You need to paste this code into your current active theme functions.php file or in a custom plugin you could make.

    After you called the "add_action" you just need to create a function like
    this:

    function create_chapter(){
   // Code goes here
}

    The 400 error and 0 response usually means wordpress didn’t find any action to fire so it just gives that error
