How To - GET todos 200 filter

Jan 30, 2021

This post and video shows how to complete the challenge GET /todos (200) ? filter to create a todo item in the application 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 (200) ? filter

Issue a GET request on the /todos end point with a query filter to get only todos which are ‘done’. There must exist both ‘done’ and ’not done’ todos, to pass this challenge.

  • GET request will return all items from the /todos end point
  • 200 is the success code meaning the request was accepted
  • ? means we need to add a URL Parameter
  • filter means it will filter based on an attribute. In this case we are asked to filter on those which are ‘done’. And this is represented by the doneStatus i.e. doneStatus=true
  • We are using this request to GET a filter list of todo items
  • Perform a GET first to see what the format of the message is
  • Add a URL parameter to the request to repeat the GET and filter the list of todos e.g. /todos?doneStatus=true

Basic Instructions

  • Issue a GET request to end point “/todos”
    • if running locally that would be
      • http://localhost:4567/todos
    • if running in the cloud that would be
  • The request should have an X-CHALLENGER header to track challenge completion
  • Look at the returned format for todos
      "id": 41,
      "title": "create todo process payroll",
      "doneStatus": true,
      "description": ""
  • we want to use the doneStatus attribute as a URL parameter
  • if you don’t see any todos in the list with a "doneStatus": true then you will need to issue a POST request to create or amend a todo item. e.g. POST todos 201
  • Issue a GET request with a URL parameter /todos?doneStatus=true
  • The response status code should be 200 because the request is accepted
  • If you get a different response code, check the URL or headers of the message because you made have made a typo.
  • If you don’t see any todos returned then you may need to create one e.g. POST todos 201
