Xend

Simple Elixir wrapper for Facebook’s Send API

Usage

Add xend as a dependency in your mix.exs:

defp deps do
  [
    {:xend, "~> 0.6.0"}
  ]
end

Add your facebook’s page access token to your configuration for xend:

config :xend, 
  fb_page_access_token: System.get_env("FB_PAGE_ACCESS_TOKEN")  

Notification types

text/3, text/4 and attachment/3 functions receive as a last argument a notification type, which can be: "REGULAR", "SILENT_PUSH", "NO_PUSH". Refer to the Send API documentation for more information on notification types.

Xend.text("USER_ID", "Do you want ketchup with your order?", quick_replies, "REGULAR")

Sending an attachment
