How to complete the challenge HEAD /todos (200)

How to issue a HEAD request and see the results of a GET request without the body of the response, this can be useful for checking the existence of an item when automating.

HEAD /todos (200)

Issue a HEAD request on the /todos end point

• HEAD request is basically a GET but doesn't return the body
• Use it to 'ping' an end point and see if it exists, or to check the Headers are working correctly
• Usually returns a 200 (if it exists) or a 404 (if it doesn't exist)

Basic Instructions

• Issue a HEAD request to end point "/todos"
  • https://apichallenges.herokuapp.com/todos
• The request should have an X-CHALLENGER header to track challenge completion
• The response status code should be 200 because the end point exists
• Compare the response with the response from GET /todos
