Microsoft R Server’s operationalization feature enables data scientists to deploy and consume web services to operationalize their R analytics. The publishService() function in mrsdeploy package can be used to publish an R code block as a new web service. After it has been deployed, the web service can be:

There are several tools like Azure AutoRest , Swagger Codegen , Swagger.io which can be used to generate API client library from swagger.json file in your preferred programming language. Now, we will look into generating API client library in R using the httr package. Using the below R code snippet, data scientists/application developers can quickly generate API Client Library in over 40 different languages immediately after publishing the web service in their R session . This method requires no extra setup, no software download/installation.

After running the above code snippet, you will find the client library in a zip file in current working directory. Unzip the file, add nuget package dependencies, add authentication workflow, add client code and begin consuming the APIs. Here is a detailed article .

To generate Client Library in your preferred language, just replace the language in httr::POST URL http://generator.swagger.io/api/gen/clients/ <language> with one of the supported languages:
