The app has the following endpoints:

GET /todos

POST /todos

Creates a new todo. The todo data should be sent in the request body as JSON.

GET /todos/{id}

Returns the todo with the given ID.

PUT /todos/{id}

Updates the todo with the given ID. The new todo data should be sent in the request body as JSON.

DELETE /todos/{id}

Deletes the todo with the given ID.
