I am currently working on a Ruby-on-Rails web-application that accepts PayPal payments through PayPal's Express Checkout and ActiveMerchant. I have done several research on ActiveMerchant's support for determining if a customer/buyer has paid using either a verified or unverified PayPal account but I got no luck on finding a helpful guide.
I find it also that ActiveMerchant is currently not well-documented so it's not that helpful at all.
Below are the relevant codes that my project is currently using. On PaymentsController#purchase, I temporarily used the #params['protection_eligibility'] and the #params['protection_eligibility_type'] methods of the ActiveMerchant::Billing::PaypalExpressResponse object that is returned by the EXPRESS_GATEWAY.purchase method call, to assess if a PayPal customer/buyer has a verified/unverified PayPal account. Later I found out that this is not a reliable basis for knowing the customer's account status.
I hope somebody can give me a wisdom on knowing whether a PayPal customer/buyer has a verified/unverified account using Ruby-on-Rails' ActiveMerchant or using other alternatives on Rails.

I used PayPal's paypal-sdk-merchant gem to do the job ActiveMerchant wasn't able to help me with (getting the status of a payer's account: verified/unverified PayPal account. I followed the installation of paypal-sdk-merchant on https://github.com/paypal/merchant-sdk-ruby
Then I set-up their samples https://github.com/paypal/merchant-sdk-ruby#samples. After setting-up the samples, go to /samples of your Rails app and you will find a lot of code generator for what ever function you need from PayPal's API. Don't forget to configure your config/paypal.yml. I configured the username, password and signature (can be obtained from your PayPal sandbox specifically your test seller account) and removed the app_id in my case.
I obtained the following code for getting a PayPal payer's account status (verified/unverified) using PayPal's samples (/samples) and placed it on a class method of a model in my app:
def self.get_paypal_payer_status(transaction_id)
require 'paypal-sdk-merchant'
api = PayPal::SDK::Merchant::API.new
get_transaction_details = api.build_get_transaction_details({
:Version => "94.0",
:TransactionID => transaction_id
})
get_transaction_details_response = api.get_transaction_details(get_transaction_details)
get_transaction_details_response.payment_transaction_details.payer_info.payer_status
end
