How to complete the challenge POST /todos (422)

By Alan Richardson · Published 2026-07-20

Issue a POST request to /todos with syntactically valid JSON that fails todo validation.

For this challenge, send doneStatus as a string rather than a boolean:

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

The response should be 422 Unprocessable Content because the request body can be parsed, but the todo data is not valid.

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

Remember to include your X-CHALLENGER header so the challenge is tracked.
