# Überauth Discord
> Discord OAuth2 strategy for Überauth.
For additional documentation on Discord's OAuth implementation see [discord-oauth2-example](https://github.com/hammerandchisel/discord-oauth2-example).
## Installation
1. Setup your application at [Discord Developers](https://discordapp.com/developers/applications/me).
1. Add `:ueberauth_discord` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:ueberauth_discord, "~> 0.3"}]
end
```
1. Add the strategy to your applications:
```elixir
def application do
[applications: [:ueberauth_discord]]
end
```
1. Add Discord to your Überauth configuration:
```elixir
config :ueberauth, Ueberauth,
providers: [
discord: {Ueberauth.Strategy.Discord, []}
]
```
1. Update your provider configuration:
```elixir
config :ueberauth, Ueberauth.Strategy.Discord.OAuth,
client_id: System.get_env("DISCORD_CLIENT_ID"),
client_secret: System.get_env("DISCORD_CLIENT_SECRET")
```
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
```
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/discord
Or with options:
/auth/discord?scope=identify%20email
By default the requested scope is "identify". Scope can be configured either explicitly as a `scope` query value on the request path or in your configuration:
```elixir
config :ueberauth, Ueberauth,
providers: [
discord: {Ueberauth.Strategy.Discord, [default_scope: "identify email connections guilds"]}
]
```
