Sample wrapper around linkedin gem to support varying user credentials.

linkedin_factory.rb

# See https://gist.github.com/1151655 for a tip how to save access token and secret in an omniauth callback.

class LinkedinFactory

  API_KEY = "123"
  SECRET_KEY = "456"

  def self.authorize_user(user)
    token = user.linkedin_connection.token
    secret = user.linkedin_connection.secret

    client = LinkedIn::Client.new(API_KEY, SECRET_KEY)
    client.authorize_from_access(token, secret)
    client
  end

  # now every API call would look like this:

  def self.get_connections(user)
    client = self.authorize_user(user)
    client.connections(:fields => ["id", "first-name", "last-name"])
  end

end
