## 3.3.0
- **New**: The new shortcode `swagger` is available to include a UI for REST OpenAPI Specifications. See the [`documentation`]({{% relref "shortcodes/swagger" %}}) for available features.
---
## 3.2.0
- **Change**: In this release the Mermaid JavaScript library will only be loaded on demand if the page contains a Mermaid shortcode or is using Mermaid codefences. This changes the behavior of `disableMermaid` config option as follows: If a Mermaid shortcode or codefence is found, the option will be ignored and Mermaid will be loaded regardlessly.

description: "Adds UI for your Swagger / OpenAPI Specifications"
title: "Swagger"
---
This shortcode uses the [RapiDoc](https://mrin9.github.io/RapiDoc) library to display your OpenAPI Specifications.
## 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.
### Example
````toml
[params]
swaggerInitialize = "{ \"theme\": \"dark\" }"
````
## Usage
Just insert your Mermaid code in the `mermaid` shortcode like this:
````go
{{</* swagger src="https://petstore3.swagger.io/api/v3/openapi.json" */>}}
````
The `src` parameter is mandatory and can be either an absolute URL or a relative one pointing into your Hugo file system.
## Example
{{< swagger src="https://petstore3.swagger.io/api/v3/openapi.json" >}}
