How to complete the challenge POST /todos (422) extra

By Alan Richardson · Published 2026-07-20

Issue a POST request to /todos with a field that is not part of the todo schema.

{
  "title": "create new todo",
  "doneStatus": false,
  "description": "created via API Challenges",
  "extra": "not part of the schema"
}

The response should be 422 Unprocessable Content because the payload is syntactically valid, but the todo data cannot be processed as a todo.
