Calling Plumber APIs from R#

Requirements#

To call APIs hosted in RStudio Connect from R, you'll need:

URL for the API endpoint hosted on RStudio Connect
API key (if your API requires authorization)

R Example#

You can use the httr package in R to call Plumber APIs from Shiny applications, R Markdown reports, other Plumber APIs, or R scripts:

library(httr)

connectApiUrl <- "https://connect.yourcompany.com/rest-api/route"
connectApiKey <- "YfB5XBRB7slkkBSEi5qr93mWJvbpXQQy"

resp <- GET(connectApiUrl,
            add_headers(Authorization = paste0("Key ", connectApiKey)))
result <- content(resp, "parsed")
print(result)

You can replace the values of connectApiUrl and connectAPIKey with your API URL and API key from RStudio Connect.

Scope#

The code examples assume that you are calling a published API in RStudio Connect that is:

Hosted on a secure server with TLS/SSL at an HTTPS endpoint
Using an API key to make an authorized call to an API
Making an HTTP GET request to the API

If your use case is different, then you can modify the example code accordingly.
