Usage in Production

[jsayegh]

Hello,

Was this library ever meant to be used for production?
Because I'm was using this library in one of my projects, and i noticed that i didn't work in production environment.

So i dug a little bit in the source code, and i found those points :

1. I see that in this function:
   

   mangopay-elixir/lib/mango_pay.ex

   Lines 137 to 149 in d31c3f1

   	defp filter_and_send(method, url, body, headers, query, bang) do
   	cond do
   	bang ->
   	case {Mix.env, method} do
   	{:dev, _} -> HTTPoison.request!(method, url, body, headers, [params: query, timeout: 4600, recv_timeout: 5000])
   	{:test, _} -> HTTPoison.request!(method, url, body, headers, [params: query, timeout: 500000, recv_timeout: 500000])
   	end
   	true ->
   	case {Mix.env, method, query} do
   	{:dev, _, _} -> HTTPoison.request(method, url, body, headers, [params: query, timeout: 4600, recv_timeout: 5000])
   	{:test, _, _} -> HTTPoison.request(method, url, body, headers, [params: query, timeout: 500000, recv_timeout: 500000])
   	end
   	end

   
   you're not taking into consideration the prod env. This will cause an error in prod and in my case i can't create a mango user.

2. I found in this line that you're always using the sandbox url:
   

   mangopay-elixir/lib/mango_pay.ex

   Lines 24 to 29 in d31c3f1

   	@doc """
   	Returns MANGOPAY_BASE_URL
   	"""
   	def base_url do
   	"https://api.sandbox.mangopay.com"
   	end

So i was wondering if i missed something? Before i submit any pull requests.
