使用PayPal重複使用的寶石升級訂閱計劃

Question

我有這種設置爲條紋，但我似乎無法弄清楚貝寶重複使用的寶石。我正在尋求允許用戶切換他們的付款計劃。如果用戶訂閱了1個月的訂閱（plan_id 1），他們應該能夠升級到年訂閱（plan_id 12）。

任何幫助，將不勝感激！

貝寶付款模式：

    end 

    def checkout_details 
     process :checkout_details 
    end 

    def checkout_url(options) 
     process(:checkout, options).checkout_url 
    end 

    def make_recurring 
     process :request_payment 
     process :create_recurring_profile, period: :monthly, frequency: 1, start_at: Time.zone.now 
    end 

    def suspend 
     process :suspend, :profile_id => @subscription.paypal_recurring_profile_token 
    end 

    def reactivate 
     process :reactivate, :profile_id => @subscription.paypal_recurring_profile_token 
    end 

    private 

    def process(action, options = {}) 
     options = options.reverse_merge(
     token: @subscription.paypal_payment_token, 
     payer_id: @subscription.paypal_customer_token,

     response = PayPal::Recurring.new(options).send(action) 
     raise response.errors.inspect if response.errors.present? 
     response 
    end

遺憾的是無法更新或變化訂閱期限爲PayPal。此訂閱將不得不取消，並建立一個新的訂閱。

API Reference爲UpdateRecurringPaymentsProfile

您將需要計算按比例分配的差異，並建立新的配置文件時，向他們收取的INITAMT，然後設置新AMT的開始日期是後，他們的任期最多可收集。
