API Keys#
API Keys allow you to programmatically access content on RStudio Connect and use the Connect Server API. They are a substitute for logging in to RStudio Connect to access content.
API Keys are not associated with any content, and can be used to access any content that the owning user could access while logged in. The best practice is to create a new API Key for each external tool that needs access to content hosted on RStudio Connect, and to give each Key a name that helps you identify the tool that uses it. When the tool no longer needs access, or if you cannot trust the Key at any time, you can quickly revoke access by deleting the Key.
Note to administrators:
API Keys need to be allowed through an authentication proxy in order to reach RStudio Connect. The Proxied Authentication section of the RStudio Connect Admin Guide has more information about adding API Key support to your proxy.
To access content with an API Key you must provide a HTTP header whose key is
Authorization
and value is Key THE_API_KEY
.
All requests to content must be made to the target URL of the published
content. You can find the target URL by clicking the "Open Solo" button in the
upper-right of the content view. (Note: on narrow screens, the "Open Solo"
button might be located in the ...
menu in the upper-right of the content
view.)
Creating and Deleting an API Key#
To create an API Key, click on the circular picture in the top-right portion of the screen. The picture may have your username next to it if you are viewing RStudio Connect on a large screen. Click the "API Keys" item in the menu that appears, and you should be taken to the API Keys page.
On the API Keys page, click "New API Key". You will be prompted to name your API Key.
After creating an API Key, you will be shown the key and given an opportunity to put it in a safe location. Once you close the dialog, you will NOT be shown the API Key again. This helps to keep your user account safe.
If you have lost an API Key, or if you simply don't need to use the API Key anymore, remove the API Key by clicking the trash bin icon on the far right column of the API Key list.
When you click the trash bin icon, a dialog will ask you to confirm that you want to delete the API Key. Successfully deleting the API Key will show a green status message at the top of the screen.
Examples#
This section contains examples of how to use API Keys to obtain or interact
with content deployed to RStudio Connect. These examples assume that your
RStudio Connect API Key is available in the environment variable
CONNECT_API_KEY
.
export CONNECT_API_KEY=q9R4ylb3K3RPB7AB46il8mxjjcYsaClW
The examples in this section use the curl
command-line utility to perform basic authenticated API Key requests against
content hosted by RStudio Connect.
The API Keys from Code section shows how to make these same requests from R, Python2, and Python3. The Connect Server API Cookbook contains recipes which interact with the Connect Server API using API Keys.
Static Content#
You can use API Keys to download resources associated with static content (plots and previously rendered HTML).
Assume you have published a plot to RStudio Connect and it has the URL:
http://rsc.company.com/content/24/target.html
.
Download this content using your API Key and the
curl
command-line program:
curl -O -H "Authorization: Key ${CONNECT_API_KEY}" \
"http://rsc.company.com/content/24/target.html"
The -O
option tells curl
to write a file named by the remote filename. In
this case, it would write to the target.html
file.
Write to a different filename (output.html
in this example) using the -o
option:
curl -o output.html -H "Authorization: Key ${CONNECT_API_KEY}" \
"http://rsc.company.com/content/24/target.html"
Plumber#
You can use API Keys to interact with a Plumber API.
Using the plumber
API definition:
## plumber.R
#* @get /mean
normalMean <- function(samples=10){
data <- rnorm(samples)
mean(data)
}
The function normalMean
is exposed through the /mean
endpoint. It takes an
optional samples
query argument.
Assume this Plumber API is available on RStudio Connect with the URL:
http://rsc.company.com/content/24/
.
You can call this API using an API Key and the curl
command-line program:
curl -H "Authorization: Key ${CONNECT_API_KEY}" \
"http://rsc.company.com/content/24/mean?samples=5"
Using API Keys from Code#
The Plumber and static content examples show that we can
access different types of content using API Keys. Those requests use the
command-line utility curl
. This section shows how to use API Keys from your
R and Python code.
All of these examples assume that your RStudio Connect API Key is available in
the environment variable CONNECT_API_KEY
and the base URL to your RStudio
Connect server is in the CONNECT_SERVER
environment variable.
export CONNECT_API_KEY=q9R4ylb3K3RPB7AB46il8mxjjcYsaClW
export CONNECT_SERVER=https://rsc.company.com/
R with httr
#
The httr
package lets you make HTTP requests from
R. This example performs an HTTP GET request against the same Plumber API we
used earlier with curl
.
library(httr)
connectServer <- Sys.getenv("CONNECT_SERVER")
connectAPIKey <- Sys.getenv("CONNECT_API_KEY")
resp <- httr::GET(connectServer,
path = "/content/24/mean",
query = list(samples = 5),
add_headers(Authorization = paste0("Key ", connectAPIKey)))
result <- httr::content(resp, as = "parsed")
The result
object is defined by parsing the JSON response data. It contains
the result computed by normalMean
in our Plumber API.
Python2 with urllib2
#
The urllib
,
urllib2
, and
urlparse
modules are part
of the Python2 standard library. This example performs an HTTP GET request
against the Plumber API we used earlier.
# -*- coding: utf-8 -*-
import json
import os
import urllib
import urllib2
import urlparse
connect_server = os.getenv("CONNECT_SERVER")
connect_api_key = os.getenv("CONNECT_API_KEY")
def build_url(base, path, **kwargs):
query = urllib.urlencode(kwargs)
parts = urlparse.urlparse(base)
parts = parts._replace(path = path, query = query)
return parts.geturl()
headers = { "Authorization": "Key %s" % connect_api_key }
request_url = build_url(connect_server, "/content/24/mean", samples = 5)
request = urllib2.Request(request_url, headers = headers)
response = urllib2.urlopen(request)
result = json.load(response)
The result
object is defined by parsing the JSON response data. It contains
the result computed by normalMean
in our Plumber API.
Python3 with urllib
#
The urllib
package is a
collection of modules for working with URLs. It is part of the Python3
standard library. This example performs an HTTP GET request against the
Plumber API we used earlier.
# -*- coding: utf-8 -*-
import json
import os
import urllib.parse
import urllib.request
connect_server = os.getenv("CONNECT_SERVER")
connect_api_key = os.getenv("CONNECT_API_KEY")
def build_url(base, path, **kwargs):
query = urllib.parse.urlencode(kwargs)
parts = urllib.parse.urlparse(base)
parts = parts._replace(path = path, query = query)
return parts.geturl()
headers = { "Authorization": "Key %s" % connect_api_key }
request_url = build_url(connect_server, "/content/24/mean", samples = 5)
request = urllib.request.Request(request_url, headers = headers)
response = urllib.request.urlopen(request)
data = response.read()
encoding = response.info().get_content_charset("utf-8")
result = json.loads(data.decode(encoding))
The result
object is defined by parsing the JSON response data. It contains
the result computed by normalMean
in our Plumber API.
