The PayPal Shopping Cart – Add to Cart and View Cart Buttons
Creating Advanced PayPal Shopping Cart Buttons on the PayPal Website
6
Working with View Cart Buttons
You need to create only one View Cart button, regardless of the number of Add to Cart buttons
that you create and add to your website. View Cart buttons on your website let buyers view
their shopping carts and the items in them. From there they can proceed to checkout.
Each time you create an Add to Cart button, PayPal gives you a chance to create a View Cart
button. Paste the same HTML button code onto your webpages for as many View Cart buttons
as you need.
The HTML button code that PayPal generates for View Cart buttons does not require
protection, because the code does not contain any payment information. You can use the
generated HTML code for any View Cart buttons that you create – the code is identical.
Generating Code for Payment Buttons and Email Payment Links
When you create Add to Cart buttons with tools on the PayPal website, PayPal generates
HTML code for website payment buttons. Then, you copy and paste the HTML code onto the
pages of your website.
In addition to HTML code, PayPal generates URL code for email payment links. Use email
payment links to add Add to Cart functionality to your email messages. If your web editing
tool or your service provider does not allow you to paste HTML code onto your webpages,
you may be able to paste the URL code for email payment links onto your webpages instead.
Protecting HTML Code for Payment Buttons
When you create Add to Cart code with tools on the PayPal website, PayPal lets your protect
the HTML button code that it generates by encrypting part of it. Protecting the HTML code of
your payment buttons helps protect against malicious tampering and fraudulent payments.
IMPORTANT: Merchants with significant payment volume are required to take precautions
on securing PayPal Payments Standard buttons.
