6 Connect Server API Cookbook

This section contains recipes for writing scripts that use the Connect Server API. It is assumed that you know the R Programming Language, but the recipes are intended to be straightforward enough to be implemented in any programming language you wish to use.

6.1 Configuring Your Scripts

It may be useful to store your RStudio Connect server URL and your API key in an environment variable, so that you can share any tools you create without exposing your personal information to other users. For example:

# ~/.Renviron

The .Renviron file will be loaded in every R session spawned under your user account.

6.2 Recipes

6.2.1 Detect Whether RStudio Connect Has Your Local R Version

  1. Obtain the server path and API keys from environment variables
  2. Obtain your local R version using R.version
  3. Call the “Get R Installation Info” endpoint. See the API Documentation for more information.
  4. Parse the response using httr::content.
  5. Check the response for the local R version. If it is not listed, the RStudio Connect server does not contain the local R version.
# set up environment
connectServer <- Sys.getenv("RSTUDIO_CONNECT_SERVER")
apiKey <- Sys.getenv("RSTUDIO_CONNECT_API_KEY")

myRVersion <- paste(R.version$major, R.version$minor, sep = ".")
resp <- GET(
    paste0(connectServer, "__api__/v1/server_settings/r",
    add_header(Authorization = paste("Key", myApiKey)
resp <- content(resp, as="parsed")
if (!(myRVersion %in% unlist(resp))) {
    print(paste("Cannot find R version", myRVersion,"on the RStudio Connect server"))
} else {
    print("The local R version was found on the RStudio Connect server")
