How To - POST todos 400

This post and video shows how to complete the challenge POST /todos (400) to fail to create a todo item in the application due to not passing validation - 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.

POST /todos (400)

Issue a POST request to create a todo but fail validation on the doneStatus field

• POST request will create a todo if the details are valid when using the /todos end point
• 400 is an error code meaning that we supplied invalid details
• In this case we are asked to make a mistake with the doneStatus field so that it fails validation server side i.e. doneStatus="bob"

Basic Instructions

• Issue a POST request to end point “/todos”
  • if running locally that would be
    • http://localhost:4567/todos
  • if running in the cloud that would be
    • https://apichallenges.herokuapp.com/todos
• The request should have an X-CHALLENGER header to track challenge completion
• The content-type in the message should be application/json because we are sending a JSON payload
• The Payload should have an error in the doneStatus. A valid doneStatus is true or false so if we send in a String like "bob" it should fail validation.

    {
        "title": "create new todo",
        "doneStatus": "bob",
        "description": "created via insomnia"
    }

• The response status code should be 400 because the request is invalid
• The body of the response will be an error message array with a single message

{
  "errorMessages": [
    "Failed Validation: doneStatus should be BOOLEAN"
  ]
}
