z “Limitations of Buy Now Buttons Created Without a PayPal Account” on page 23 z “Unclaimed Payments From Buttons Created Without a PayPal Account” on page 23 z “Creating a Basic Buy Now Button Without a PayPal Account” on page 24

Limitations of Buy Now Buttons Created Without a PayPal Account

Consider the following limitations of payment buttons that you create and add to your website before you sign up for your PayPal account.

z You cannot claim the payments that people authorize during checkout. PayPal collects and

holds the payments as unclaimed until you sign up for your PayPal account.

z Buyers must have a PayPal account to pay you. Any ability to pay by credit card is

disabled.

z PayPal limits the features that you can specify with the button creation tool, such as:

– Saving your buttons in your PayPal account – Tracking inventory

N OTE: You cannot create payment buttons without a PayPal account if Javascript is disabled

in your browser.

Unclaimed Payments From Buttons Created Without a PayPal Account

For buttons that you create without a PayPal account, payments that buyers authorize are held as unclaimed by PayPal until you sign up. PayPal holds your unclaimed payments under the email address that you specify when you create the buttons. Make sure to use the same email address when you sign up for your account. Otherwise PayPal cannot transfer your unclaimed payments to your PayPal account balance.

In their PayPal accounts, buyers see unclaimed payments that they made to you from Buy Now buttons that you created without a PayPal account. Such unclaimed payments are displayed in their recent account activity and in their transaction history. Until you finish signing up for your PayPal account, buyers can cancel your unclaimed payments and recover their funds.

Co-Branding the Checkout Pages with Your Logo and Colors

The basic checkout experience displays your email address or your business name in the upper left corner of the checkout pages. You can enhance the checkout experience by setting up custom page payments in your account profile to specify logos and colors that match the style of your website. PayPal uses the logo and colors to display the checkout pages. In addition, you can specify logos and colors with advanced HTML variables that you add to the code of your button.

For more information, see:

z “Co-Branding the PayPal Checkout Pages” on page 267 z “HTML Variables for Displaying PayPal Checkout Pages” on page 358

Managing Buy Now Transactions

IMPORTANT: PayPal recommends that you turn Payment Data Transfer on when you

turn Auto Return on. With Auto Return on, PayPal redirects people to your website from an alternative PayPal payment confirmation page that does not display a View Printable Receipt link, so people cannot print PayPal payment receipts. Payment Data Transfer provides the transaction information that you need to let people print receipts from your website.

To learn more, see “Auto Return” on page 271.

z Payment Data Transfer – PayPal includes information about the completed transaction

when you use a return URL or Auto Return to send people back to your website. Use the information that Payment Data Transfer provides to display a “thank you, print your receipt” page on your website.

To learn more, see the Order Management Integration Guide

Using Email Notices to Track Buy Now Transactions

PayPal sends you email notices when:

z Payments are made. z Payments are pending. z Payments are canceled.

Generally, PayPal sends email notices to the primary email address of your account. PayPal can send email notices to an alternate email address, such as to someone in your

organization who handles order processing or accounting. Add the additional email address to your account profile. Then, use that email address as the one to receive payments when you use the button creation tool on the PayPal website. Specify the alternate email address as the value for the business HTML variable when you write the HTML code yourself.

For more information, see Step 10 in the instructions for “Step 1 – Specifying Basic Features

of Your Buy Now Button” on page 40, or Appendix A, “HTML Variables for Website Payments Standard.”

Generating Code for Payment Buttons and Email Payment Links

When you create Buy Now 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.

Website Payments Standard Integration Guide September 2008 37

Single-Item Payments – Buy Now Buttons

Creating Advanced Buy Now Buttons on the PayPal Website

In addition to HTML code, PayPal generates URL code for email payment links. Use email payment links to add Buy Now 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 Buy Now 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 Website Payments Standard buttons.

For more information, see Chapter 6, “Securing Your Website Payments Standard Buttons

Using the Button Creation Tool for Advanced Buy Now Buttons

z “The Basic Steps for Using the Tool With Buy Now Buttons” on page 38 z “Saving Buy Now Buttons in Your PayPal Account” on page 39 z “Tracking Inventory” on page 39 z “Adding Advanced Features to Buy Now Buttons With HTML Variables” on page 40 z “Step 1 – Specifying Basic Features of Your Buy Now Button” on page 40 z “Step 2 – Tracking Inventory With Your Buy Now Button” on page 44 z “Step 3 – Adding Advanced Features to Your Buy Now Button” on page 47 z “Copying and Pasting the Buy Now Code” on page 50

N OTE: If JavaScript is disabled in your browser, PayPal provides an alternative tool described

The Basic Steps for Using the Tool With Buy Now Buttons

The button creation tool for Buy Now buttons is a single webpage with three sections:

z Step 1 – Choose button type and enter payment details – This section lets you specify

the details of your Buy Now button. You can specify product options that buyers can choose, and you can specify item-specific charges for shipping and tax.

z Step 2 – Track inventory (optional) – This section lets you control whether to save your

button in your PayPal account. If you save your button, you can enter information that PayPal uses to track inventory on the item.

z Step 3 – Customize advanced features (optional) – This section lets you work with

advanced features of Buy Now buttons, including letting buyers change item quantities. If you are familiar with HTML programming and the advanced HTML variables supported by Website Payments Standard buttons, you can enter them here.

38 September 2008 Website Payments Standard Integration Guide

Single-Item Payments – Buy Now Buttons

Creating Advanced Buy Now Buttons on the PayPal Website

One section at a time is open for you to work with. To work with another section, click its step bar to expand it.

You can switch between the sections as often as you like, until you click the Create Button button at the bottom of the page. Then, PayPal generates the code for your button and displays it on the You are viewing your button code page. Copy the code and paste it onto your webpage, and your payment button is complete.

Saving Buy Now Buttons in Your PayPal Account

By default, the button creation tool saves payment buttons in your PayPal account. The tool saves your button and generates the code when you click the Create Button. You must copy and paste the generated code onto your webpages, whether or not you save your button at PayPal. The generated code is shorter for saved buttons, because PayPal keeps most of the information about your button in your account, instead of placing it in the code that you add to your website.

Saving your payment buttons in your PayPal account has these benefits:

z Your payment buttons are more secure, because the generated code that add to your website

contains no information that can be tampered with to produce fraudulent payments.

z You can edit the details and options for your payment buttons in your PayPal account,

without changing the button code that you added to your website.

N OTE: If you change product options, you must copy and paste the code newly generated

by PayPal to replace the code that you pasted previously.

z You can track inventory.

Use the Step 2 section of the button creation tool to control whether your button is saved in your PayPal account. You can have a maximum of 1,000 saved buttons in your PayPal account.

Tracking Inventory

PayPal can track inventory for items that you sell with Buy Now buttons if you save them in your PayPal account. You can track inventory for the item itself or by its product options.

Website Payments Standard Integration Guide September 2008 39

Single-Item Payments – Buy Now Buttons

Creating Advanced Buy Now Buttons on the PayPal Website

If you track inventory, PayPal helps you avoid oversold situations. PayPal sends you an alert by email when your inventory on hand falls to or below the alert level you specify. You have the option to let oversold transactions go through or to warn buyers and prevent them from buying more than your quantity on hand.

Use the Step 2 section of the button creation tool to specify the information that PayPal uses to track inventory.

Adding Advanced Features to Buy Now Buttons With HTML Variables

Some advanced features of payment buttons can be specified only with HTML variables. If you are familiar with HTML programming and the advanced HTML variables supported by Website Payments Standard payment buttons, you can enter them in the button creation tool before the button code is generated.

Use the Step 3 section of the button creation tool to enter advanced HTML variables that you want to include in your payment button.

Creating Donate Buttons Before You Create Your PayPal Account

You can create basic Donate buttons, add them to your website, and begin accepting contributions before you sign up for your PayPal account. Read the following topics to learn more about creating Donate buttons before you create your PayPal account.

z “Limitations of Donate Buttons Created Without a PayPal Account” on page 74 z “Unclaimed Payments From Buttons Created Without a PayPal Account” on page 74 z “Creating a Basic Donate Button Without a PayPal Account” on page 75

Limitations of Donate Buttons Created Without a PayPal Account

Consider the following limitations of payment buttons that you create and add to your website before you sign up for your PayPal account.

z You cannot claim the payments that people authorize during checkout. PayPal collects and

holds the payments as unclaimed until you sign up for your PayPal account.

z Donors must have a PayPal account to pay you. Any ability to pay by credit card is

disabled.

z PayPal limits the features that you can specify with the button creation tool, such as saving

your buttons in your PayPal account:

N OTE: You cannot create payment buttons without a PayPal account if Javascript is disabled

in your browser.

Unclaimed Payments From Buttons Created Without a PayPal Account

For buttons that you create without a PayPal account, payments that donors authorize are held as unclaimed by PayPal until you sign up. PayPal holds your unclaimed payments under the email address that you specify when you create the buttons. Make sure to use the same email address when you sign up for your account. Otherwise PayPal cannot transfer your unclaimed payments to your PayPal account balance.

In their PayPal accounts, donors see unclaimed payments that they made to you from Donate buttons that you created without a PayPal account. Such unclaimed payments are displayed in their recent account activity and in their transaction history. Until you finish signing up for your PayPal account, donors can cancel your unclaimed payments and recover their funds.

In addition to HTML code, PayPal generates URL code for email payment links. Use email payment links to add Donate 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 Donate 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 Website Payments Standard buttons.
