Ueberauth Xero

A Xero OAuth2 strategy for Überauth.

Installation

1. Create an application at Xero Developer Platform

2. Add :ueberauth_xero to your list of dependencies in mix.exs:

def deps do
  [
    {:ueberauth_xero, "~> 0.1.0"}
  ]
end

1. Add Xero to your Überauth configuration:

config :ueberauth, Ueberauth,
  providers: [
    xero: {Ueberauth.Strategy.Xero, []}
  ]

1. Update your provider configuration:

config :ueberauth, Ueberauth.Strategy.Xero.OAuth,
  client_id: {System, :get_env, ["XERO_CLIENT_ID"]},
  client_secret: {System, :get_env, ["XERO_CLIENT_SECRET"]}

1. Include the Überauth plug in your controller:

defmodule MyApp.AuthController do
  use MyApp.Web, :controller
  plug Ueberauth
  ...
end

1. Create the request and callback routes if you haven't already:

scope "/auth", MyApp do
  pipe_through :browser

  get "/:provider", AuthController, :request
  get "/:provider/callback", AuthController, :callback
end

1. Your controller needs to implement callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses.

Configuring scopes

           "openid email profile offline_access accounting.settings.read accounting.transactions accounting.contacts"
       ]}
