HI,
I finally didn’t use any plugin for amazon payment, & did with Amazon
simple pay…
It offers a good ruby code, to create checkout button.

here is the code given by amazon for creating button. The Price,return
url can be dynamically changed.

        require 'base64'
        require 'openssl'
        module PayNowWidgetUtils
        def generate_signed_form(access_key, aws_secret_key, 

form_params)
form_params[‘accessKey’] = access_key
str_to_sign = “”
form_params.keys.sort.each { |k| str_to_sign +=
“#{k}#{form_params[k]}” }
digest = OpenSSL::Digest::Digest.new(‘sha1’)
hmac = OpenSSL::HMAC.digest(digest, aws_secret_key,
str_to_sign)
form_params[‘signature’] = Base64.encode64(hmac).chomp
signed_form =<<-STARTFORM

STARTFORM

             form_params.each do |key, value|
               next unless key and value
               signed_form +=<<-"FORMELEM"
                 <input type="hidden" name="#{key}" value="#{value}" 
        FORMELEM
             end

             signed_form +=<<-ENDFORM
                 <input type="image"
                        src="https://authorize.payments-sandbox.amazon.com/pba/images/amazonPaymentsButton.jpg"
        border="0" >
             </form>
        ENDFORM

        return signed_form
        end
        end

        include PayNowWidgetUtils
        ACCESS_KEY = '<your amazon aws access key>'
        SECRET_KEY = '<your amazon aws secret key>'
        print generate_signed_form(ACCESS_KEY, SECRET_KEY,
                                 'amount' => 'USD 100',
                                 'description' => 'Test Button',
                                 'referenceId' => 'txn1102',
                                 'returnUrl' => 

http://localhost:3000/success’,
‘abandonUrl’ =>
http://localhost:3000/fail’)
