-3. Create a mock REST service.

-     Let's use a mock REST service to create a REST API from scratch.
-
-     A mock service with a JSON response `{"hello": "world"}` is provided by default when you use the service URL as `http://run.mocky.io/v2/5185415ba171ea3a00704eed`, which appears in the [https://designer.mocky.io/](https://designer.mocky.io/) mock service. Let's use the HTTP protocol instead of the HTTPS protocol for this guide.

-    !!! tip
-        Optionally, to test this service, copy the service URL [http://run.mocky.io/v2/5185415ba171ea3a00704eed](http://run.mocky.io/v2/5185415ba171ea3a00704eed) and navigate to it on a new browser. You should see the following JSON message.
