**How to protect a page in Redocly so that it requires a specific role?**

To secure a page in Redocly, you can use the `x-security` field in your OpenAPI definition. To require a specific role, like "pearl," you can set the `security` property in your API definition. Here's an example:


```yaml
paths:
  /debrief.md:
    get:
      security:
        - pearl: []
```

This will ensure that only users with the "pearl" role can access the `/debrief.md` page. [^1](https://redocly.com/docs/redoc/config)

**How to create a code walkthrough in Redocly?**

Redocly supports code snippets and examples, but it doesn't have a built-in feature for creating code walkthroughs. However, you can use the `x-code-samples` property to provide code examples related to your API endpoints. Here's an example:


```yaml
paths:
  /example:
    get:
      summary: An example endpoint
      x-code-samples:
        - lang: javascript
          source: |
            const response = await fetch('/example');
            const data = await response.json();
```

This will display a code sample in the API documentation. [^1](https://redocly.com/docs/redoc/config)

**How to show only the mock server in the try it console?**

Redocly uses the `servers` field in your OpenAPI definition to determine which server to use in the try it console. To show only the mock server, you can specify it in the `servers` array like this:


```yaml
servers:
  - url: https://mock-server.com/api
```

This will ensure that the try it console only shows the mock server. [^1](https://redocly.com/docs/redoc/config)

**How to run API monitoring using Redocly on a regular schedule?**

Redocly doesn’t have a built-in feature for running API monitoring on a regular schedule. However, you can use external tools like Postman or Apigee to monitor your APIs and set up scheduled tests. [Source](https://redocly.com/docs/realm/monitor/api-monitor)

**How to make headings purple in Redocly?**

To change the color of headings in Redocly, you can use custom CSS. You can target the heading elements using their CSS selectors and apply the desired color. Here’s an example:


```css
h1, h2, h3, h4, h5, h6 {
  color: purple;
}
```

You can add this CSS to your project’s `styles.css` file. [^2](https://redocly.com/docs/realm/style/concepts/styling)
