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) 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 A good starting point is to generate the SDK online: https://github.com/swagger-api/swagger-codegen#online-generators https://github.com/swagger-api/swagger-codegen#online-genera...
