Abstract: 

Consume, control and serve REST APIs with R:

APIs are everywhere. The beauty of APIs is that APIs allow for a simple communications method between two systems, and they are extremely useful for gathering data from systems, as well as command and control of remote resources. Most modern APIs are web REST APIs. In this session, we learn about using R for three kinds of API tasks: consumption, command/control and serving APIs.

From a consumption perspective, we discuss how to work with the httr, curl, and jsonlite packages. We show examples of constructing API requests, submitting them, and working with the responses. We discuss tips and tricks to optimize the workflow.
to interface with web REST APIs for many purposes.

From a command & control perspective, we discuss several packages included in the cloudyr (http://cloudyr.github.io/) project, which allow you to manage and execute tasks in the cloud. We show examples of creating resources and augmenting your data using APIs.

Last, we discuss the plumber R package, which allows users to expose existing R code as a service available to others on the Web. We discuss how to take models and functions and expose them as APIs so others can use them.
