You can sync GitBook pages with an OpenAPI or Swagger file or a URL to include auto-generated API methods in your documentation.

### OpenAPI block

GitBook's OpenAPI block is powered by [Scalar](https://scalar.com/), so you can test your APIs directly from your docs.

{% openapi src="<https://petstore3.swagger.io/api/v3/openapi.json>" path="/pet" method="post" %}
<https://petstore3.swagger.io/api/v3/openapi.json>
{% endopenapi %}
