Headless commerce separates frontend from backend. Backend (head) provides data via API. Frontend consumes and renders freely. This guide explores the architecture, benefits, and implementation considerations.
What is Headless Commerce
Concept
E-commerce backend without coupled frontend.
Architecture
APIs expose functionality. Frontend consumes.
Flexibility
Any frontend can use the backend.
Traditional vs Headless
