Behaviour for defining custom OAuth providers.

Example

defmodule MyApp.Auth.Discord do
  use Amur.Provider

  def strategy, do: Assent.Strategy.OAuth2

  def base_config do
    [
      base_url: "https://discord.com/api",
      authorization_endpoint: "/oauth2/authorize",
      token_endpoint: "/oauth2/token",
      user_endpoint: "/users/@me"
    ]
  end

  def normalize_user(user) do
    %{uid: user["id"], email: user["email"], name: user["username"]}
  end
end
