Per the SDKs ... If you've a Swagger/OpenAPI spec, you can use Swagger Codegen (https://github.com/swagger-api/swagger-codegen https://github.com/swagger-api/swagger-codegen), a free and open-source project, to generate API clients (SDKs) in C#, Ruby, PHP, Java, ObjC, etc. Here is an example: https://github.com/wing328/petstore-php https://github.com/wing328/petstore-php You can also use Swagger Codegen to generate server stub in SpringMVC, PHP Slim and more. Disclosure: I'm a top contributor to Swagger Codegen.
