JSONPlaceholder User Profile

Load a sample user record from JSONPlaceholder — handy for prototyping Set/Mapper nodes and mock APIs.

JSONPlaceholder User Profile

JSONPlaceholder provides fake REST data for demos. This template fetches user 1 and passes the JSON downstream.

What this workflow does

  1. Input placeholder label (for canvas clarity)
  2. HTTP GET /users/1
  3. Output returns the full object

Use cases

  • Test expressions like $UserApi.body.email patterns with stable JSON
  • Teach HTTP + mapping before touching real customer APIs
