How To - GET todos id 404

Dec 15, 2020

This post and video shows how to complete the challenge GET /todos/id 404 using Insomnia.

What are the API Challenges?

Our API Challenges Application has a fully functional cloud hosted API, and a set of challenges to work through.

GET /todos/id (404)

Issue a GET request on the /todos/{id} end point for a todo that does not exist

  • This will show you a 404 status code in the API response
  • 404 status code means Not Found
  • The {id} means, replace this with the id of a non-existant todo item

Basic Instructions

  • Issue a GET request to end point “/todos/{id}”
    • if running locally that would be
      • http://localhost:4567/todos/{id}
    • if running in the cloud that would be
  • The request should have an X-CHALLENGER header
  • The response status code should be 404 because {id} does not exist
  • an error message should be shown in the response body
