Consume a REST Service Example | MuleSoft Documentation
# Consume a REST Service Example
The following example illustrates how to configure Anypoint Connector for HTTP (HTTP Connector) to consume a REST service by setting up the HTTP **Listener** source and the **Request** operation.
To accomplish this example, you must:
  * Consume a REST API service using default HTTP configurations.
  * Test the HTTP request.
  * Edit the configuration to make secure HTTPS requests.
  * Test the HTTPS request.


The following screenshot shows the Anypoint Studio app flow for this example:
## Create the Mule Application
To create the Mule flow:
  1. In the **Mule Palette** view, select the HTTP **Listener** source and drag it on to the canvas. The source initiates the flow by listening for incoming HTTP message.
  2. On the **Listener** configuration screen, optionally change the value of the **Display Name** field.
  3. Set **Path** to `/trigger`.
  4. Click the plus sign (**+**) next to the **Connector configuration** field to configure a global element that can be used by all instances of the HTTP **Listener** in the app.
  5. On the **General** tab, configure the following fields:
     * **Host** : `All Interfaces [0.0.0.0] (default)`
     * **Port** : `8081`
  6. Drag an HTTP **Request** operation to the right of HTTP **Listener**.
  7. Set **URL** to `http://jsonplaceholder.typicode.com/users`.
  8. Save your Mule app.
  9. Click the project name in **Package Explorer** and then click **Run** > **Run As** > **Mule Application**.
  10. Open a web browser, and go to `localhost:8081/trigger`. The **Listener** hears the request on port `8081`, and starts the app. The list of users appears in the browser.
  11. Return to the **Request** configuration screen and set the **URL** field to `https://jsonplaceholder.typicode.com/users` to use the HTTPS protocol.
  12. Click the plus sign (**+**) next to the **Connector configuration** field to configure a global element that can be used by all instances of the HTTP **Request** in the app.
  13. Set **Port** to `443`.
  14. Save and run your Mule app.
  15. Open a web browser, and go to `localhost:8081/trigger`. The **Listener** hears the request on port `8081`, and starts the app. The list of users appears in the browser.


## XML for Consuming a REST API Service
Paste this code into your Studio XML editor to quickly load the flow for this example into your Mule app:
```
