Openapi Markdown

Posted on  by admin

Open API is a specification and complete framework implementation for describing, producing, consuming, and visualizing RESTful web services. ServiceStack implements the OpenAPI Spec back-end and embeds the Swagger UI front-end in a separate plugin which is available under OpenAPI NuGet package:

You can enable Open API by registering the OpenApiFeature plugin in AppHost with:

Then you will be able to view the Swagger UI from /swagger-ui/. A link to Swagger UI will also be available from your /metadataMetadata Page.

Open API Attributes

Each route could have a separate summary and description. You can set it with Route attribute:

You can set specific description for each HTTP method like shown below:

You can further document your services in the OpenAPI with the new [Api] and [ApiMember] annotation attributes, e,g: Here’s an example of a fully documented service:

Please note, that if you used ApiMember.DataType for annotating SwaggerFeature then you need to change the types to OpenAPI type when migrating to OpenApiFeature. For example, annotation of

need to be changed to

Here is the table for type migration

Swagger Type (DataType)OpenAPI Type (DataType)OpenAPI Format (Format)

You can use [ApiAllowableValues] lets you anotate enum properties as well as a restriction for values in array, e.g:

Group APIs with Tags

You can tag the DTO with [Tag] attribute. Attributes are are annotated by the same tag are grouped by the tag name in Swagger UI. DTOs can have multiple tags, e.g:

You can Exclude properties from being listed in OpenAPI with:

Exclude properties from being listed in OpenAPI Schema Body with:

Exclude Services from Metadata Pages


To exclude entire Services from showing up in OpenAPI or any other Metadata Services (i.e. Metadata Pages, Postman, NativeTypes, etc), annotate Request DTO’s with:

Operation filters

You can override operation or parameter definitions by specifying the appropriate filter in plugin configuration:

Available configuration options:

  • ApiDeclarationFilter - allows to modify final result of returned OpenAPI json
  • OperationFilter - allows to modify operations
  • SchemaFilter - allows to modify OpenAPI schema for user types
  • SchemaPropertyFilter - allows to modify propery declarations in OpenAPI schema

Properties naming conventions

You can control naming conventions of generated properties by following configuration options:

  • UseCamelCaseSchemaPropertyNames - generate camel case property names
  • UseLowercaseUnderscoreSchemaPropertyNames - generate underscored lower cased property names (to enable this feature UseCamelCaseModelPropertyNames must also be set)


Change default Verbs

If left unspecified, the [Route] attribute allows Services to be called from any HTTP Verb which by default are listed in the Open API specification under the most popular HTTP Verbs, namely GET, POST, PUT and DELETE.

This can be modified with AnyRouteVerbs which will let you specify which Verbs should be generated for ANY Routes with unspecified verbs, e.g. we can restrict it to only emit routes for GET and POST Verbs with:

Miscellaneous configuration options

  • DisableAutoDtoInBodyParam - disables adding body parameter for request DTO to operations
  • LogoUrl - url of the logo image for Swagger UI


Virtual File System

The docs on the Virtual File System shows how to override embedded resources:

Overriding OpenAPI Embedded Resources

ServiceStack’s Virtual File System supports multiple file source locations where you can override OpenAPI’s embedded files by including your own custom files in the same location as the existing embedded files. This lets you replace built-in ServiceStack embedded resources with your own by simply copying the /swagger-ui files you want to customize and placing them in your Website Directory at:

Injecting custom JavaScript

As part of the customization you can add custom patch.js and patch-preload.js:

which will be injected in the /swagger-ui index page, patch-preload.js is embedded before swaggerUi.load() is called:

So you can use it to customize the swaggerUi configuration object before it’s loaded, whilst patch.js is embedded just before the end of the </body> tag, e.g:

Swagger UI Security

There are 2 custom security methods supported Bearer and Basic Auth.

You can specify to use Swagger’s support for API Key Authentication with:

This will instruct Swagger to use their API Key Authentication when clicking the Authorize button which will be sent in API requests to your Authenticated Services. As the value field is for the entire Authorization HTTP Header you’d need to add your JWT Token or API Key prefixed with Bearer :

Which you can use to use to Authenticate with “Bearer token” Auth Providers like API Key and JWT Auth Providers.

Basic Auth in OpenAPI

You can instruct Swagger to use HTTP Basic Auth with:

This lets Users call protected Services using the Username and Password fields in Swagger UI. Swagger UI sends these credentials with every API request using HTTP Basic Auth, which can be enabled in your AppHost with:

To login, you need to click “Authorize” button.

And then enter username and password.

Also you can click “Try it out” button on services, which requires authentication and browser will prompt a window with user/password field for entering basic auth credentials.

Alternatively you can authenticate outside Swagger (e.g. via an OAuth Provider) which will also let youcall protected Services in /swagger-ui.

Generating AutoRest client

You can use OpenAPI plugin to automatically generate client using Autorest. To use AutoRest first install it from npm:

Then you need to download the Open API specification for your Services using a tool like curl:

Open Api Markdown Software

Or using iwr if you have PowerShell installed:

You can then use the openapi.json with autorest to generate a client for your API in your preferred language, e.g:

This will generate directory containing your model types and REST operations that you can use with the generated client, e.g:

AutoRest clients will allow usage of tooling that have adopted AutoRest and is a good stop gap solution for generatingnative clients for languages that Add ServiceStack Reference doesn’t support yet likePython and Ruby.

AutoRest Generated Clients vs Add ServiceStack Reference

However AutoRest generated clients are similar to WCF Service Reference generated clients where it generates RPC-style Clients that emits both implementation logic and models for sending each request that’s coupled to external HttpClient and JSON.NET dependencies. This approach generates significantly more code generation that populates a directory containingmultiple implementation and Model classesgenerated for each Service.

In contrast Add ServiceStack Reference adopts the venerable Data Transfer Object, Gateway and Remote Facade Service patterns where it only needs to generateclean, implementation-free DTO models that it captures in a single source file for all supported languages.

The generated DTOs are cleaner and more reusable where it isn’t coupled to any Serialization implementation andcan be reused in any of ServiceStack’s message-based Service Clients and Serialization Formatsor different Service Gateway implementations.The models are also richer where it’s able to include additional metadata attributes and marker interfaces that isn’t possible when tunneling through a generic API specification.

The use of intelligent generic Service Clients will always be able to provide a richer more productive development experience that can enable higher-level, value-added functionality like Structured Error Handling, Smart HTTP Caching, Auto Batching, Encrypted Messaging, AutoQuery Streaming, Request Compression, integrated authentication and lots more.

Known issues

Autorest generated clients do not support application/octet-stream MIME type, which is used when service returns byte[] array. You can track this issue on Github.

Publish Azure Management API

Login to Azure Portal and search for API management service.

Choose API management service. In opened window click Add button.

Fill the creation form. Put your own values in Name, Resource Group, Organization name and Administrator email. When creation form will be ready, click Create button.

Wait while Management API will be activated. It can take more than forty minutes. When it ready click on created API management resource.

In opened window click APIs - PREVIEW menu item on the left pane.

Choose OpenAPI specification in Add API section.

Fill the url with location of you services, ended with /openapi or just click Upload button and upload OpenAPI json definition, which is available at /openapi path of your services.
