 Parameter Name | Description
 --- | ---
 url | The url pointing to `swagger.json` (Swagger 2.0) or the resource listing (earlier versions) as per [Swagger Spec](https://github.com/swagger-api/swagger-spec/).
+authorizations | An authorization object to be passed to swagger-js.  Setting it here will trigger inclusion of any authorization or custom signing logic when fetching the swagger description file.  Note the object structure should be `{ key: AuthorizationObject }`
 spec | A JSON object describing the Swagger specification. When used, the `url` parameter will not be parsed. This is useful for testing manually-generated specifications without hosting them. Works for Swagger 2.0 specs only.
 validatorUrl | By default, Swagger-UI attempts to validate specs against swagger.io's online validator. You can use this parameter to set a different validator URL, for example for locally deployed validators ([Validator Badge](https://github.com/swagger-api/validator-badge)). Setting it to `null` will disable validation. This parameter is relevant for Swagger 2.0 specs only.
 dom_id | The id of a dom element inside which SwaggerUi will put the user interface for swagger.
