How to complete the challenge PUT /todos no id (422)

By Alan Richardson · Published 2026-08-01

Issue a PUT request to /todos without an id in the URL or the request body.

The /todos endpoint exists, but the API cannot know which todo to update. Because the request reaches a valid endpoint but is missing required update information, the response should be 422 Unprocessable Content.

Basic Instructions

• Send PUT /todos
• 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 so the missing identifier is the relevant error
• Verify the response status is 422

Example body:

{
  "title": "missing identifier",
  "doneStatus": false,
  "description": "no id in URL or body"
}
