LinkedIn v2
WARNING: DANGER WILL ROBINSON
⚠️ This project is no longer actively maintained. ⚠️
NOW BACK TO YOUR REGULARLY SCHEDULED PROGRAMMING
Ruby wrapper for v2 if the LinkedIn API. This gem is entirely based on emorikawa's excellent linkedin-oauth2 gem.
If you are using OAuth 1.0, see hexgnu/linkedin If you are using OAuth 2.0 and the v1 LinkedIn API, see emorikawa/linkedin-oauth2, on which this gem is based.
Installation
In Bundler:
gem "linkedin-v2", "~> 0.1.0"
Otherwise:
[sudo|rvm] gem install linkedin-v2
Usage
Step 1: Register your application with LinkedIn. They will give you a Client ID (aka API Key) and a Client Secret (aka Secret Key)
Step 2: Use your Client ID and Client Secret to obtain an Access Token from some user.
Step 3: Use an Access Token to query the API.
api = LinkedIn::API.new(access_token)
me = api.profile
Step 1: Register your Application
You first need to create and register an application with LinkedIn here.
You will not be able to use any part of the API without registering first.
Once you have registered you will need to take note of a few key items on your Application Details page.
-
API Key - We refer to this as your client id or
client_id
-
Secret Key - We refer to this as your client secret or
client_secret
-
Default Scope - This is the set of permissions you request from
users when they connect to your app. If you want to set this on a
request-by-request basis, you can use the
scope
option with theauth_code_url
method. -
OAuth 2.0 Redirect URLs - For security reasons, the url you enter
in this box must exactly match the
redirect_uri
you use in this gem.
You do NOT need OAuth User Token nor OAuth User Secret. That is for OAuth 1.0. This gem is for OAuth 2.0.
Step 2: Getting An Access Token
All LinkedIn API requests must be made in the context of an access token. The access token encodes what LinkedIn information your AwesomeApp® can gather on behalf of "John Doe".
There are a few different ways to get an access token from a user.
-
You can use LinkedIn's Javascript API to authenticate on the front-end and then pass the access token to the backend via this procedure.
-
If you use OmniAuth, I would recommend looking at decioferreira/omniauth-linkedin-oauth2 to help automate authentication.
-
You can do it manually using this linkedin-oauth2 gem and the steps below.
Here is how to get an access token using this linkedin-oauth2 gem:
Step 2A: Configuration
You will need to configure the following items:
- Your client id (aka API Key)
- Your client secret (aka Secret Key)
- Your redirect uri. On LinkedIn's website you must input a list of
valid redirect URIs. If you use the same one each time, you can set it
in the
LinkedIn.configure
block. If your redirect uris change depending on business logic, you can pass it into theauth_code_url
method.
# It's best practice to keep secret credentials out of source code.
# You can, of course, hardcode dev keys or directly pass them in as the
# first two arguments of LinkedIn::OAuth2.new
LinkedIn.configure do |config|
config.client_id = ENV["LINKEDIN_CLIENT_ID"]
config.client_secret = ENV["LINKEDIN_CLIENT_SECRET"]
# This must exactly match the redirect URI you set on your application's
# settings page. If your redirect_uri is dynamic, pass it into
# `auth_code_url` instead.
config.redirect_uri = "https://getawesomeapp.io/linkedin/oauth2"
end
Step 2B: Get Auth Code URL
oauth = LinkedIn::OAuth2.new
url = oauth.auth_code_url
Step 2C: User Sign In
You must now load url from Step 2B in a browser. It will pull up the
LinkedIn sign in box. Once LinkedIn user credentials are entered, the box
will close and redirect to your redirect url, passing along with it the
OAuth code as the code
GET param.
Be sure to read the extended documentation around the LinkedIn::OAuth2 module for more options you can set.
Note: The OAuth code only lasts for ~20 seconds!
Step 2D: Get Access Token
code = "THE_OAUTH_CODE_LINKEDIN_GAVE_ME"
access_token = oauth.get_access_token(code)
Now that you have an access token, you can use it to query the API.
The LinkedIn::OAuth2
inherits from intreda/oauth2's OAuth2::Client
class. See that gem's documentation for more usage examples.
Step 3: Using LinkedIn's API
Once you have an access token, you can query LinkedIn's API.
Your access token encodes the permissions you're allowed to have. See Step 2 and this LinkedIn document for how to change the permissions. See each section's documentation on LinkedIn for more information on what permissions get you access to.
