ruby on rails - Can't verify(check) paypal account

Question

I need to verify PayPal account, when user sign_up.

I have function(source - http://curry.byteally.com/finding-verification-status-of-a-paypal-account-ruby-on-rails-paypal-adaptive-accounts-getverifiedstatus/)

I entered my credentials and changed.

I put it i my static_pages_controller(for now).

   def verify_paypal
     ...
//change:
if res.status == 200
 @xml = XmlSimple.xml_in(res.content)
 #check if the status node exists in the xml
if @xml['accountType']!=nil
account_type = @xml['accountType'][0]
if account_type.to_s() == "Business"
    render :text => "Business account!"
elseif account_type.to_s() == "Premier"
    render :text => "Premier Account!"
elseif account_type.to_s() == "Personal"
    render :text => "Personal account!"
else
    render :text => "Account type not null but not a valid PayPal account type."
end
   end

Added line in my routes.rb

  post "static_pages/verify_paypal"

In my views:

   <%= link_to "verify", static_pages_verify_paypal_path, :method => :post %>

But it constantly gives me text:

    "Gee! sorry! something went seriously wrong"

what mean, that my user isn't registered in PayPal(but it is!).

First question to this line:

    "emailAddress" => params[:paypal] 

Can I change it into

    current_user.email

Second question - Where is problem and what I'm doing wrong ?

Answer 1

The API call structure is sound.

However, when you say you entered your credentials, did you make sure that you are using the right credentials for the right environment? Live credentials, and live accounts do not exist within the sandbox and viceversa. You can't check a live account's status against the checkbox because it simply does not exists in the sandbox "universe".

That would be the first thing to look at. If you feel your environments are correct, can you post the contents of res.content to see what came back from the HTTP call?
