May 9, 2021

This post and video shows how to complete the challenge GET /todos JSON (200) to successfully GET all the todos in JSON format.

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 JSON (200)

Issue a GET request on the /todos end point with an Accept header of application/json to receive results in JSON format

  • GET request will receive a response with all the todo items
    • e.g. GET /todos to get all the todo items
  • 200 is a success code, in this case it means the end point exists and the `todo items were returned
  • Accept means that an Accept header was added to specify that the todos should be returned in JSON format
  • add the X-CHALLENGER header to track progress

Basic Instructions

  • Issue a GET request to end point “/todos”
    • if running locally that endpoint would be
      • http://localhost:4567/todos
    • if running in the cloud that endpoint would be
  • The request should have an Accept header specifying JSON format by using a value of application/json
  • The request should have an X-CHALLENGER header to track challenge completion
  • The response status code should be 200 when all the details are valid.
  • Check the body of the message has JSON format data
  • Check the content-type header in the response has application/json
