    No idea what keepalive is, but if I want to send a fetch request to a php backend I would usually do something like this:

            fetch("backend.php", {
          method: "POST",
          headers: {
            "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8",
          },
          body: "data=" + data,
        })
          .then((response) => response.json())
          .then((response) => doWhatYouWant(response))
          .catch((error) => alert("Error : " + error));

    You could call fetch with json as content-type and use method POST as you allready tried, you also have to serialize the content on the body

     fetch("backend.php", {
          method: "POST",
          headers: {
            "Content-Type": "application/json",
          },
          body: JSON.stringify({ name: "blablabla" }),
});
