Introducing PayPal Payments Pro

You can accept credit and debit cards and PayPal payments directly on your website using 2

API-based solutions: Direct Payment and Express Checkout. You must integrate with both

Direct Payment and Express Checkout to use PayPal Payments Pro, known as Website

Payments Pro outside the U.S.

 PayPal Payments Pro Overview

 Additional Features of PayPal Payments Pro

 PayPal Payments Pro API Operations

 Website Payments Pro Regional Differences

Getting Related Information

All PayPal documentation is available on x.com, including video demos, forums and developer

resources.

 For information about administrative tasks you can perform from your PayPal account such

as adding users, setting up custom page styles, and managing multiple currency balances,

see the

Merchant Setup and Administration Guide.

 If you use the Payflow API to process transactions with PayPal as your internet merchant

account, see

Gateway Developer Guide and Reference.

PayPal Payments Pro Overview

PayPal Payments Pro includes Direct Payment, Express Checkout, and additional PayPal

solutions and tools, such as Virtual Terminal, Fraud Management Filters, and reference

transactions.

 Direct Payment enables you to accept both debit and credit cards directly from your site.

 Express Checkout enables you to accept payments from PayPal accounts in addition to

debit and credit cards.

The following diagram shows the relationship between Direct Payment and Express Checkout

to a buyer.

Introducing PayPal Payments Pro

10 April 2012 PayPal Payments Pro Integration Guide

From your shopping cart, a buyer can either checkout with Express Checkout, starting from

the Checkout with PayPal button on your Shopping Cart page, or pay directly by credit or

debit card using Direct Payment.

If a buyer pays using Express Checkout, PayPal provides a checkout experience that

streamlines checkout. Even if buyers do not pay using Express Checkout, they can still pay by

credit or debit card using Direct Payment. In this case, buyers might need to enter payment,

billing, and shipping information. In both cases, buyers stay on your website or are sent to the

page of your choice.

You must implement both an Express Checkout flow and a Direct Payment flow to use PayPal

Payments Pro. You implement the Express Checkout flow by calling PayPal’s Express

Checkout API operations, which guides a buyer through the checkout process. You implement

the Direct Payment flow using your own code, for which PayPal provides an API operation to

process the credit or debit card payment.

NOTE: Purchases through Direct Payment are not covered by the PayPal Seller Protection

Policy.

Additional Features of PayPal Payments Pro

PayPal Payments Pro consists of APIs for accepting credit card, debit card, and PayPal

payments; these payments can be immediate, authorized for later capture, and they can be

recurring payments. PayPal Payments Pro also includes standalone applications for accepting

payments.

In addition, PayPal Payments Pro includes Fraud Management Filters for automatic review

and management of risk.

Settlements and Captured Payments

Often, you accept a payment and ship goods immediately, which is refered to as sale. In

addition to immediate payments, Direct Payment and Express Checkout both allow you to

authorize payments to be captured later, which is referred to as an authorization. An

authorization is useful, for example, when you want to reserve a buyer’s funds pending the

shipment of goods; the actual payment is captured when the goods are shipped. An

authorization can be reauthorized one time if necessary; for example, when you are unable to

ship within 3 days of the authorization.

Express Checkout provides an additional option, called an order, which you use when a single

authorization is insufficient. You can create multiple authorizations and capture them as part

of the same order. This would be useful, for example, when an order is split into multiple

shipments and you need to capture a payment each time part of the order is shipped.

Recurring Payments

You can support recurring payments to manage subscriptions and other payments on a fixed

schedule. Direct Payment and Express Checkout both process recurring payments.

When you support recurring payments for a buyer, you create a recurring payments profile.

The profile contains information about the recurring payments, including details for an

optional trial period and a regular payment period. Both periods contain information about the

payment frequency and payment amounts, including shipping and tax, if applicable.

After creating a profile, PayPal automatically queues payments based on the billing start date,

billing frequency, and billing amount. Payments reoccur until the profile expires, there are too

many failed payments to continue, or you cancel the profile.

Permission to allow recurring payments is established by the buyer setting up a billing

agreement with the merchant on PayPal. For Express Checkout, the billing agreement can be

established either in advance or when the buyer first makes a purchase; in either case, it occurs

when you call Express Checkout API operations. For direct payment, it occurs when you make

an explicit call to set up the billing agreement.

Recurring payments using reference transactions is an alternative, which enables you to handle

payments for varying amounts of money on a varying schedule. A reference transaction is a

financial transaction from which subsequent transactions can be derived; for example, a buyer

can make a purchase on your site and the PayPal transaction ID, called a reference transaction

ID, can later be used to initiate another transaction.

NOTE: The use of recurring payments with direct payment may incur additional fees.

Virtual Terminal

PayPal’s Virtual Terminal is a web-based application that allows you to accept credit card

payments. It is available to merchants in the United States, Canada, France, and the United

Kingdom. Virtual Terminal provides your business with the functionality similar to a stand-

alone credit card-processing terminal. Virtual Terminal is ideal when you receive orders by

phone, fax, or by mail and want to accept credit cards. An optional card reader is available to

process face-to-face purchases; however, some restrictions apply. You can use Virtual

Terminal on any computer with an internet connection and a web browser.

For more information about Virtual Terminal, see

Virtual Terminal Users Guide.

Hosted Solution

Hosted Solution, which is available to merchants in the United Kingdom as part of PayPal

Payments Pro, is a fast and easy way to add transaction processing to your website. It is a

secure, PayPal-hosted, web-based payment solution that allows you to securely send your

buyers to PayPal’s payment page to authorize and process transactions. Buyers pay with a

debit or credit card, or their PayPal account. You do not have to capture or store credit card

information on your website, thereby helping towards achieving PCI compliance. Hosted

Solution is the choice for merchants who prefer a solution where all financial details are

handled by PayPal.

For more information about Hosted Solution for UK merchants, see

Website Payments Pro

Hosted Solution Integration Guide.

Fraud Management Filters

Fraud Management Filters (FMF) provide you filters that identify potentially fraudulent

transactions. There are 2 categories of filters:

 Basic filters screen against data such as the country of origin and the value of transactions.

PayPal provides basic filters for Business accounts and Website Payments Pro accounts.

 Advanced filters screen data such as credit card and addresses information, lists of high-

risk indicators, and additional transaction characteristics. Website Payments Pro merchants

can upgrade to use these filters.

NOTE: Using advanced filters might incur additional charges.

For more information about Fraud Management Filters, see

Fraud Management Filters

Event Notification

In most cases you can use the GetTransactionDetails API operation to determine the

information you need about a transaction. However, there may be some cases in which you

must set up IPN; for example, when you need automatic notification about actions, such as

disputes and their resolution.

IPN is a message service that PayPal uses to notify you about events, such as:

 Instant payments, including Express Checkout, Adaptive Payments, and direct credit card

payments, and authorizations, which indicate a sale whose payment has not yet been

collected

 eCheck payments and associated status, such as pending, completed, or denied, and

payments pending for other reasons, such as those being reviewed for potential fraud

 Recurring payment and subscription actions

 Chargebacks, disputes, reversals, and refunds associated with a transaction

Introducing Direct Payment

Direct Payment lets buyers who do not have a PayPal account use their credit cards without

leaving your website. PayPal processes the payment in the background.

 The Direct Payment User Experience

 User Interface Recommendations for Direct Payment Checkout

The Direct Payment User Experience

Direct Payment enables buyers to pay by credit or debit card during your checkout flow. You

have complete control over the experience; however, you must consider PCI compliance.

When buyers choose to pay with a credit or debit card, they enter their card number and other

information on your website. After they confirm their order and click Pay, you complete the

order in the background by invoking the DoDirectPayment API operation. Buyers never

leave your site. Although PayPal processes the order, buyers aren’t aware of PayPal’s

involvement; PayPal will not even appear on the buyer’s credit card statement for the

transaction.

The following diagram shows a typical Direct Payment flow:

The numbers in the diagram correspond to the following implementation steps:

1. On your checkout pages, you need to collect the following information from a buyer to be

used in the DoDirectPayment request:

– Amount of the transaction

– Credit card type

– Credit card number

– Credit card expiration date

– Credit card CSC value

– Cardholder first and last name

– Cardholder billing address

The following example shows the collection of credit card information from a US buyer

after the transaction amount has been determined:

NOTE: In some cases, the billing address and CSC value may be optional. You must also

identify debit on your PCI compliant checkout page when you reference a direct

card checkout image.

2. You must also retrieve the IP address of the buyer's browser and include this with the

request.

3. When a buyer clicks the Pay button, invoke the DoDirectPayment API operation.

4. The PayPal API server executes the request and returns a response.

– Ack code (Success, SuccessWithWarning, or Failure)

– Amount of the transaction
