Quick Answer
jQuery + REST APIs: use $.ajax with method: "PUT"/"DELETE" (not just GET/POST), set contentType: "application/json" and JSON.stringify(data) for JSON request bodies, handle HTTP status codes in the error callback (xhr.status), add auth headers globally with $.ajaxSetup({headers: {Authorization: "Bearer " + token}}), and use .always() for cleanup regardless of success/failure.
Answer
Use $.ajax() with JSON handling. Centralize API utilities. Use global AJAX handlers for auth, errors, and loading indicators.
