Hi.
Configuration as following

config =OAuth2Ex.config(
  id:            client_id],
  secret:        client_secret],
  authorize_url: auth_url],
  token_url:     token_url],
  scope:         premissions],
  callback_url:  callback]
)

token=OAuth2Ex.Token.browse_and_retrieve!(config, receiver_port: oauth_port])
    response = OAuth2Ex.HTTP.get(token, token_url])

I guess I should set callback_url same the url of this function.
Because I run code, server wait there for something..

However, facebook give me following message :

{
   "error": {
      "message": "Invalid redirect_uri: Given URL is not allowed by the Application configuration.",
      "type": "OAuthException",
      "code": 191
   }
}

I've looked into the dropbox doc, and the implementation seems same as facebook.
So I don't know what's wrong around here.

Hi. Thanks for trying out. I haven't been able to test with Facebook API, but I think the callback url you're using should be registered in the facebook beforehand. I can see several related stackoverflow topics.
