Paypal recurring payments with variable amount 2 (in Spain) - ruby-on-rails

Question

some days ago, I wrote this post regarding Paypal recurring payments with variable amount Paypal recurring payments with variable amount
I marked it as fixed, however it is not.
First, I decided to develop approach 1 (by removing old profile and creating a new one). This worked. But, after that I realized, that I didn´t cover all my requirements. So finally, the right approach for me is number 2. This means, as #Andrew Angell suggested, I will develop a custom billing system that bills the customers. For that, I will create Billing Agreements and I will use the returned ids to execute Reference transactions with the amount I need and whenever I need. So far, it´s right?
According to Paypal docs, this is possible: https://developer.paypal.com/docs/classic/express-checkout/integration-guide/ECReferenceTxns/
So, I´m trying to follow the steps, so first a execute a setExpressCheckout:
# Paypal setExpressCheckout
def setExpressCheckout(billingType, returnURL, cancelURL, price, description)
#api = PayPal::SDK::Merchant::API.new
if billingType == "credit-card"
billingType = "Billing"
else
billingType = "Login"
end
#set_express_checkout = #api.build_set_express_checkout({
SetExpressCheckoutRequestDetails: {
ReturnURL: returnURL,
CancelURL: cancelURL,
LocaleCode: "US",
LandingPage: billingType,
PaymentDetails: [{
NotifyURL: returnURL,
OrderTotal: {
currencyID: "EUR",
value: price
},
ShippingTotal: {
currencyID: "EUR",
value: "0"
},
TaxTotal: {
currencyID: "EUR",
value: "0"
},
PaymentDetailsItem: [{
Name: description,
Quantity: 1,
Amount: {
currencyID: "EUR",
value: price
},
}],
PaymentAction: "Authorization" # To authorize and retain the funds, and when booking is confirmed capture them.
}],
BillingAgreementDetails: [{
BillingType: "MerchantInitiatedBillingSingleAgreement",
BillingAgreementDescription: description
}]
}
})
# Make API call & get response
#express_checkout_response = #api.set_express_checkout(#set_express_checkout)
# Access Response
if #express_checkout_response.success?
#token = #express_checkout_response.Token
puts "setExpressCheckout completed OK :)"
#paypal_url = #api.express_checkout_url(#express_checkout_response)
else
puts "setExpressCheckout KO :("
#express_checkout_response.Errors
puts "#express_checkout_response=" + #express_checkout_response.inspect
end
#express_checkout_response
end
However, I get this error:
#LongMessage="Merchant not enabled for reference transactions", #ErrorCode="11452"
It´s quite clear, just need to contact Paypal support guys and ask them to enable Reference transactions in my Paypal sandbox account. Right? I already did it and I´m just waiting.
However, what really worries me, is that I called Paypal support and they told me that this approach will not work in Spain. Although it´s in the doc, it´s only working in UK. Is this true?
If it´s true, I´m really in a trouble, because as far as I know, Paypal doesn´t not support subscriptions with variable amount.

Answer 1

Paypal technical support guy has enabled my sandbox account to reference transactions. I have developed the logic and it´s working. At least, in Sandbox and in Spain.
So, I will assume, it works.
Bad the Paypal guy on the phone that told me it wasn´t possible.
