    text
    copied!<p>I'm using the <a href="https://github.com/nov/paypal-express" rel="nofollow">paypal-express</a> gem in my ruby on rails project. I want users to be able to purchase digital goods on my web application. I've created a controller with a new and create action. The <code>new</code> action generates a PayPal link which users visit. Users are returned from PayPal to the <code>create</code> action where I attempt to complete the order.</p> <p>Everything works fine in development when using sandbox credential, when using production credentials I receive a "10007 - permission denied" error from PayPal.</p> <p>I have triple checked the username/password/API signature i've entered for production and they are correct (The user is sent to the correct PayPal store).</p> <p>Here is my controller:</p> <pre><code>class DigitalPaymentsController &lt; ApplicationController before_filter :authenticate_user!, :only =&gt; [ :new, :create ] def new Paypal.sandbox! unless Rails.env.production? response = paypal_request.setup( payment_request, success_url, cancel_url, :no_shipping =&gt; true ) @paypal_url = response.redirect_uri end def create begin response = paypal_request.checkout!(params[:token], params[:PayerID], payment_request) if response.payment_info.first.payment_status == 'Completed' # TODO: Handle complete payments else # TODO: Handle non complete payments end rescue Paypal::Exception::APIError =&gt; e # Payment has failed, failure details are in e.message, also check params end end private def paypal_request @request ||= Paypal::Express::Request.new( :username =&gt; PAYPAL_USERNAME, :password =&gt; PAYPAL_PASSWORD, :signature =&gt; PAYPAL_SIGNATURE ) end def payment_request @payment_request ||= Paypal::Payment::Request.new( :currency_code =&gt; :USD, :amount =&gt; 15, :items =&gt; [{ :name =&gt; "Awesome Product", :description =&gt; 'Description of awesomeness', :amount =&gt; 15, :category =&gt; :Digital }] ) end end </code></pre> <p>Having a look into the paypal-express gem, it seems to call <code>DoExpressCheckoutPayment</code> on the PayPal API and pass the PayerID and the Token. The PayPal API documentation didn't list a way to resolve my error (10007).</p>
