How to complete the challenge PUT /api/challenger/database/guid (Update)

By Alan Richardson · Published 2026-07-31

First retrieve your todo database with GET /api/challenger/database/{guid}.

Then send that JSON payload to PUT /api/challenger/database/{guid} with Content-Type: application/json. A successful restore returns 204 No Content.

Try it now

If you want to inspect the todo database payload first, get it with GET /api/challenger/database/{guid}. See the solution.

GET /api/challenger/database/{guid} to get the todo database payload

PUT /api/challenger/database/{guid} to restore the todo database

Lessons Learned

• PUT /api/challenger/database/{guid} restores todo data from a previously exported database payload.
• 204 No Content indicates the restore was accepted without returning the restored dataset.
• State restore tests need a follow-up GET /api/todos to prove the body took effect.

Suggested Experiments

• Change todo data, restore the database export with PUT, then verify individual todo ids returned.
• Remove one todo from the saved database payload and observe how the restore changes the collection.
