Überauth Meli (Mercado Libre)

Mercado Libre OAuth2 strategy for Überauth.

Installation

1. Setup your application at Mercado Libre for Developers.

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

    def deps do
      [{:ueberauth_meli, "~> 0.1"}]
    end

3. Add Meli to your Überauth configuration:

    config :ueberauth, Ueberauth,
      providers: [
        meli: {Ueberauth.Strategy.Meli, []}
      ]

4. Update your provider configuration:

   config :ueberauth, Ueberauth.Strategy.Meli.OAuth,
     client_id: System.get_env("MELI_CLIENT_ID"),
     client_secret: System.get_env("MELI_CLIENT_SECRET")

5. Include the Überauth plug in your controller:

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

Or with options:

/auth/meli?scope=read,write

By default the requested scope is "read". Scope can be configured either explicitly as a scope query value on the request path or in your configuration:

config :ueberauth, Ueberauth,
  providers: [
    meli: {Ueberauth.Strategy.Meli, [default_scope: "read,write"]}
  ]
