# Überauth Battle.net
> Battle.net OAuth2 strategy for Überauth.
## Installation
1. Setup your application on the [Battle.net Developer Portal](https://dev.battle.net).
1. Add `:ueberauth_bnet` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:ueberauth_bnet, "~> 0.1"}]
end
```
1. Add the strategy to your applications:
```elixir
def application do
[applications: [:ueberauth_bnet]]
end
```
1. Add Battle.net to your Überauth configuration:
```elixir
config :ueberauth, Ueberauth,
providers: [
bnet: {Ueberauth.Strategy.Bnet, []}
]
```
1. Update your provider configuration:
```elixir
config :ueberauth, Ueberauth.Strategy.Bnet.OAuth,
client_id: System.get_env("BNET_CLIENT_ID"),
client_secret: System.get_env("BNET_CLIENT_SECRET"),
region: System.get_env("BNET_REGION")
```
By default the US region is used.
1. Include the Überauth plug in your controller:
```elixir
defmodule MyApp.AuthController do
use MyApp.Web, :controller
plug Ueberauth
...
end
```
1. Create the request and callback routes if you haven't already:
```elixir
scope "/auth", MyApp do
pipe_through :browser
get "/:provider", AuthController, :request
get "/:provider/callback", AuthController, :callback
end
```
Battle.net expects a HTTPS redirect URI, extra steps might be necessary to set it up for your dev environment.
1. Your controller needs to implement callbacks to deal with `Ueberauth.Auth` and `Ueberauth.Failure` responses.
For an example implementation see the [Überauth Example](https://github.com/ueberauth/ueberauth_example) application.
## Calling
Depending on the configured url you can initial the request through:
/auth/bnet
Or with options:
/auth/bnet?scope=wow.profile%20sc2.profile
By default the requested scope is empty and the region is US. Scope can be configured either explicitly as a `scope` query value on the request path or in your configuration:
```elixir
config :ueberauth, Ueberauth,
providers: [
bnet: {Ueberauth.Strategy.Bnet, [scope: "wow.profile sc2.profiles"]}
]
```
Available scopes are: `wow.profile` and `sc2.profile`.
