 `id` is a special field. All objects have an `id` field. However, you don't need to specify an `id` in a `create` method; all `create` methods will return the created `id` back to you.
 
-All `update` and `delete` methods take an `id` to specify the desired object. `update` takes the fields to update as a second argument — it does not take a full object. That means even if a field is required, you don't have to pass it to `update`. For example, a `category` requires the `group_id` field, however `updateCategory(id, { name: "Food" })` is a valid call. Required means that an `update` can't set the field to `null` and `create` method must always have it.
