Überauth PagerDuty

PagerDuty OAuth2 strategy for Überauth.

Installation

  1. Setup your application at PagerDuty Developer.

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

    def deps do
      [
        {:ueberauth_pagerduty, "~> 0.1.1"}
      ]
    end
  3. Add PagerDuty to your Überauth configuration:

    config :ueberauth, Ueberauth,
      providers: [
        pagerduty: {Ueberauth.Strategy.PagerDuty, []}
      ]
  4. Update your provider configuration:

    config :ueberauth, Ueberauth.Strategy.PagerDuty.OAuth,
      client_id: System.get_env("PAGERDUTY_CLIENT_ID"),
      client_secret: System.get_env("PAGERDUTY_CLIENT_SECRET"),
      redirect_uri: System.get_env("PAGERDUTY_REDIRECT_URI")

    Or, to read the client credentials at runtime:

    config :ueberauth, Ueberauth.Strategy.PagerDuty.OAuth,
      client_id: {:system, "PAGERDUTY_CLIENT_ID"},
      client_secret: {:system, "PAGERDUTY_CLIENT_SECRET"},
      redirect_uri: {:system, "PAGERDUTY_REDIRECT_URI"}
  5. Include the Überauth plug in your router:

    defmodule MyApp.Router do
      use MyApp.Web, :router
    
      pipeline :browser do
        plug Ueberauth
        ...
       end
    end
  6. 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
  7. Your controller needs to implement callbacks to deal with Ueberauth.Auth and Ueberauth.Failure responses.

For an example implementation see the Überauth Example application.

Calling

Depending on the configured url you can initiate the request through:

/auth/pagerduty

Or with options:

/auth/pagerduty?scope=write

By default the requested scope is "write". This provides both read and write access to the PagerDuty API (via classic auth).

Scope can be configured either explicitly as a scope query value on the request path or in your configuration:

config :ueberauth, Ueberauth,
  providers: [
    pagerduty: {Ueberauth.Strategy.PagerDuty, [default_scope: "write"]}
  ]
