Subscription Integration - Paypal using Nodejs and ReactJS

问题

I am trying to integrate Paypal subscriptions into a ReactJS and NodeJS website.

I have the following code on the client:

    window.paypal.Buttons({
        createSubscription: function(data, actions) {
            return actions.subscription.create({
                'plan_id': 'P-5WJ4336006859111JLWVUDTQ'
            });
        },
        onCancel: function (data) {
            this.props.handleResponse({error: "The user cancelled"});
        },
        onApprove: function(data, actions) {
            alert('You have successfully created subscription ' + data.subscriptionID);
        }
    }).render('#paypal-button');

What code do I need on the server (node) side to make this work?

Can someone please point me in the right direction?
