title: Paypal Checkout with a Product_Id
body: <p>I'm currently using the <a href="https://developer.paypal.com/docs/checkout/integrate/" rel="nofollow noreferrer">Smart Checkout Button</a> from Paypal to purchase Customer.</p>
  <p>I'm also listening for Webhook Notification.</p>
  <p>Everything is working fine, but my problem is that I have multiple products the User can buy. So I need to get an information about the product in my Webhook.</p>
  <p>Is there any way to create products in Paypal like in Stripe or to put some extra values like product id  to the Checkout, so that I know which product the user bought.</p>
  <p>I tried it with some fields like &quot;item&quot; below, but I could'nt access them inside my webhook.</p>
  <pre><code>  var button = paypal.Buttons({
      fundingSource: fundingSource,
      createOrder: function(data, actions) {
    // This function sets up the details of the transaction, including the amount and line item details.
    return actions.order.create({
      purchase_units: [{
        amount: {
          currency_code: 'EUR',
          value: '0.69'
        },
        item:&quot;product_id12345&quot;
      }]
    });
  }
    });
  </code></pre>
