{{% tab name="shortcode" %}}

````go
{{</* swagger src="https://petstore3.swagger.io/api/v3/openapi.json" */>}}
````

{{% /tab %}}
{{% tab name="partial" %}}

### Parameter

| Name                 | Default          | Notes       |
|:---------------------|:-----------------|:------------|
| **src**              | _&lt;empty&gt;_  | The URL to the OpenAPI Specification file. This can be relative to the URL of your page if it is a leaf or branch bundle. |

{{% notice note %}}
If you want to print out (or generate a PDF) from your Swagger documentation, don't initiate printing directly from the page because the elements are optimized for interactive usage in a browser.

Instead, open the [print preview]({{% relref "basics/configuration/#activate-print-support" %}}) in your browser and initiate printing from that page. This page is optimized for reading and expands most of the available sections.

## Configuration

Swagger is configured with default settings. You can customize Swagger's default settings for all of your files thru a JSON object in your `config.toml` or override these settings per page thru your pages frontmatter.

The JSON object of your `config.toml` / frontmatter is forwarded into Swagger's initialization. At the moment, only the `theme` setting is supported.

The `theme` setting can also be set by your used color variant. This will be the sitewide default and can - again - be overridden by your settings in `config.toml` or frontmatter.

### Global Configuration File

````toml
[params]
  swaggerInitialize = "{ \"theme\": \"dark\" }"
````

## Example
