REST APIs
REST APIs is a core skill in Web Development. You understand how clients and servers exchange data over REST APIs — endpoints, methods, status codes and JSON. In a FUTEAC roadmap it takes about 6 hours of focused learning, and the free Roadmap Generator places it in the right week of your personal plan, after its prerequisites, at the pace you choose.
What you will be able to do
You understand how clients and servers exchange data over REST APIs — endpoints, methods, status codes and JSON.
Learn these first
- Fetch & AJAX
You can load and send data in the background with fetch, handle loading and error states, and update the page without reloads.
Roadmaps that teach REST APIs
- Frontend Developer roadmap — 16 weeks at about 2 hours a day
Goal of this roadmap: Build modern, responsive websites and web apps with HTML, CSS, JavaScript and React.
- Full-Stack Developer roadmap — 24 weeks at about 2 hours a day
Goal of this roadmap: Build complete web applications — frontend, backend APIs, databases and deployment.
What you can learn next
REST APIs is a prerequisite for this skill — learning it unlocks it in your roadmap:
- API Design

About 6 hours of focused learning. REST APIs is a core skill, and in a FUTEAC roadmap it is placed in the right week for your goal and pace — after everything it depends on, never before.
What should I learn before REST APIs?
Learn Fetch & AJAX first. REST APIs builds directly on that skill, so the order matters: with the prerequisites in place, REST APIs is noticeably easier and faster to pick up.
What can I learn after REST APIs?
REST APIs unlocks API Design. Those skills list REST APIs as a prerequisite, which is why FUTEAC roadmaps schedule them after it.
Which roadmaps include REST APIs?
REST APIs is part of the Frontend Developer, Full-Stack Developer roadmaps. Each roadmap orders it at the point where it is needed for that goal, surrounded by the skills it connects to.
