# Überauth Meli (Mercado Libre)
> Mercado Libre OAuth2 strategy for Überauth.
## Installation
1. Setup your application at [Mercado Libre for Developers](https://developers.mercadolivre.com.br/).
1. Add `:ueberauth_meli` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:ueberauth_meli, "~> 0.1"}]
end
```
1. Add Meli to your Überauth configuration:
```elixir
config :ueberauth, Ueberauth,
providers: [
meli: {Ueberauth.Strategy.Meli, []}
]
```
1. Update your provider configuration:
```elixir
config :ueberauth, Ueberauth.Strategy.Meli.OAuth,
client_id: System.get_env("MELI_CLIENT_ID"),
client_secret: System.get_env("MELI_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 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:
```elixir
config :ueberauth, Ueberauth,
providers: [
meli: {Ueberauth.Strategy.Meli, [default_scope: "read,write"]}
]
```
