Build your first REST API
Build your first REST API visually with three nodes, run it live and see the backend code it generates.
Featured tutorial1

Start from a blank canvas and finish with a working REST route. You will start a flow with an Execute node, add an API Endpoint that defines the route, return a JSON message with a Response node and run it live in the built-in debugger — then inspect the real backend code Fimaflow generates from your canvas.
What you will build
- Start a flow with an Execute node
- Add an API Endpoint node and set the route
- Return a JSON message with a Response node
- Run the flow live in the debugger
