通过使用paypal-ruby-sdk创建Paypal定期订阅计划时，如何使卖方支付交易费用

Question

I'm using paypal-ruby-sdk to create recurring subscriptions by credit cards. When I create subscription plan, I set transaction(setup_fee) fee to zero. So paypal sandbox returns webhooks and the transaction fee is paid to PayPal according to their transaction fee rules.

But I'm not sure who pays the fee to PayPal. I want a seller to pay the fee.
The below code shows subscription plan creation I wrote:

plan = Plan.new({
  :name => self.unique_key,
  :description => self.title,
  :type => 'fixed',
  :payment_definitions => [{
    :name => self.unique_key,
    :type => 'REGULAR',
    :frequency_interval => 'MONTH',
    :frequency => '1',
    :cycles => '999',
    :amount => {
      :currency => 'USD',
      :value => (self.price / 100.0).ceil(2).to_s
    }
  },
  :merchant_preferences => {
    :setup_fee => {
      :currency => 'USD',
      :value => 0
    },
    :cancel_url => packages_url,
    :return_url => profile_url + "#subscription",
    :max_fail_attempts => '0',
    :auto_bill_amount => 'YES',
    :initial_fail_amount_action => 'CONTINUE'
  }
})

I'm not sure it will charge fee to the seller. Any help would be welcome.
Thank you.

Answer 1

The fees will be on the receiver side and not the seller side.

Thank you.
