## In code

This code will also ensure that only the user can see the info

```javascript
// Create something only the user can see if user only on
let create = await API.post("ServerlessExampleCRUD", "/ServerlessExample", {
  body: {
    ID: "3",
    ItemDescription: "Description",
    ItemName: "Item Three",
    ItemPrice: 99,
  },
});
console.log(create);

// Fetch if only user can fetch
let counter = await API.get(
  "ServerlessExampleCRUD",
  "/ServerlessExample/object/3",
  {}
);
console.log("> CounterOne.counter", counter);
```
