How to complete the challenge PUT /todos/{id} not found (404)

By Alan Richardson · Published 2026-08-01

Issue a PUT request to /todos/{id} where the URL id does not exist, and do not include an id in the request body.

This is an update attempt against a specific URL resource. Since that resource does not exist, the response should be 404 Not Found.

Basic Instructions

• Send PUT /todos/{id} where {id} does not exist
• Add an X-CHALLENGER header to track challenge completion
• Set Content-Type to application/json
• Do not include an id field in the JSON payload
• Include a valid title
• Verify the response status is 404

Example body:

{
  "title": "missing todo",
  "doneStatus": false,
  "description": "URL id does not exist"
}

Try it now
