Setting Up Your PayPal Payment Methods

To configure PayPal for your Magento store:

1. In the Magento Admin Panel, choose System→Configuration. Select the PayPal tab on the left. You'll see the following options:
2. In the Merchant Account panel, you can set the following values:
   • Merchant Country - Select the merchant's country, i.e. the country to which the Merchant's PayPal account is associated. The countries available for selection are listed according to the PayPal Worldwide reference. If the merchant country is not specified, its value is taken from Default Country field located under System→Configuration→General tab→Countries Options panel. The payment method selections available below will be changed to reflect only those that are valid for this country.
   • Email Associated with PayPal Merchant Account - Enter the email address that was used when registering a merchant account with PayPal. If not yet registered with PayPal, simply enter your email address. If the Email Associated with PayPal Merchant Account field is empty, the Website Payments Standard payment method will be unavailable and the Express Checkout method is only available if the API credentials are specified. Instant Payment Notifications (IPNs) from PayPal are not available if the email address for sending IPNs and the one specified in the Merchant Account configuration are different.
3. In the Select a PayPal Solution panel, select which of the following PayPal payment methods you'd like to have available in your store:
   • Express Checkout
   • Website Payments Standard
   • Website Payments Pro
   • Website Payments Pro Payflow Edition (includes its own Express Checkout)
   • Payflow Pro Gateway
   • Express Checkout with Payflow Pro Gateway
4. Depending on the payment method(s) you've selected, the corresponding payment method configuration panel will becomes available below. Each of these is described in more detail in the following sections. Enter the required information for each of your selected PayPal payment method(s).
5. After you've entered the required configuration information, click the [Save Config] button in the upper right.

The following PayPal payment methods require that your customers also have customer accounts in PayPal:

• Express Checkout
• Website Payments Standard
• Express Checkout for Payflow Pro

These PayPal payment methods do not require your customers to have a PayPal account and allow them to enter their credit card information directly on your website during the checkout process:

• Website Payments Pro
• Website Payments Pro Payflow Edition
• Payflow Pro Gateway

Express Checkout

With this payment method enabled, the [Checkout with PayPal] button becomes available on the product view pages, in the shopping cart, and in the mini shopping cart. Clicking the button allows the customer to review the shopping cart price information on the PayPal site. To use this method of payment, the customer needs to log on to his or her customer account in PayPal. The payment system uses the customer’s billing and shipping information taken from the customer’s PayPal account. The customer can then continue and will be redirected to the Magento Review Order page. After placing the order in Magento, the payment information is submitted to PayPal and the payment transaction is settled there.

If the customer does not use the express checkout button, the payment information is submitted to PayPal after an order is placed.The Express Checkout payment method can be used standalone; if the API credentials are not specified, the payment method is used in the unilateral mode. With the Express Checkout payment method enabled, make sure that the API Username, API Password, and API Signature fields are populated; otherwise, the payment method will work in the unilateral mode.

Express Checkout is automatically disabled if the Website Payments Pro Payflow Edition payment method is enabled.

The Express Checkout payment method is applied in all countries from the PayPal Worldwide reference list.

Config Options in the Express Checkout Settings Panel

• Title - Enter the name of the payment method that will be displayed to the customer in the Payment Information section of the shopping cart Checkout page. This parameter can be set up for each store view. We recommend that you use the PayPal value in the Title field for each store view.
• Sort Order - When you use several payment methods, in the Sort Order field determine the order this method will be displayed in the Payment Information section of the shopping cart Checkout page in the frontend.
• Payment Action - Choose the way payments will be authorized in the PayPal payment system and the entities that will be created in the backend as a result of the payment procedure. The following options are available:
  • Authorization - payments are only authorized at the side of the PayPal system and only an order is created in the backend of your store. The store administrator needs log to on to the merchant account on the PayPal site and capture the transaction.
  • Sale- a payment is authorized and captured at PayPal's side and as a result an order and an invoice are created in the backend of your store.
• Payment Applicable From - Choose customers of which countries can use this method of payment. Choose between the following options:
  • All Allowed Countries – customers from the default countries list can use this payment method. (The default list of countries is defined in the Allow Countries field located under System > Configuration > General > Countries Options.)
  • Specific Countries – only customers whose billing address includes one of the countries listed in the Countries Payment Applicable From field that becomes available can use this payment method. The field basically works as a filter; so that this payment method will only be listed for those customers whose billing address is one of these selected countries.
• Debug Mode - Specify whether data messages about all sent to the payment system and received from it information will be written into the system log file. The credit card related information is not written to the log file in order to prevent credit card fraud.
• Transfer Cart Line Items - Choose whether shopping cart lines, i.e. items and their prices, are transferred separately line by line or they are transferred as one whole with their price total value. If the parameter is enabled, the Transfer Shipping Options field becomes available.
• Transfer Shipping Options - Allows the customer change shipping addresses and shipping method on the PayPal web site. In the live mode, the parameter works via the HTTPS protocol only. The parameter does not work if more than ten shipping options are available.
• Shortcut on Shopping Cart - Choose whether the customer can use the express checkout button on the shopping cart page and in the mini shopping cart. Clicking the button redirects the customer to the PayPal site where the shopping cart price information can be reviewed. If the parameter is set to No, the express checkout button on the product page still remains available.
• Shortcut on Product View - Choose whether the express checkout button is available on the product view page.
• Shortcut Buttons Flavor - Choose whether a dynamic or a static PayPal Acceptance Mark image will be displayed next to the payment method in the Payment Information section of the shopping cart Checkout page. (For better image management, we recommend that you replace static images in your system with dynamic ones.)
  • Dynamic – The appearance of dynamic images is dynamically changed by PayPal. When signing up for a PayPal campaign, the appearance of the image dynamically changes during the campaign based on the parameter information that you add to the image URL. The express checkout image displayed in the following figure is a default one used by PayPal.
  • Static – The static images cannot be changed dynamically. When participating in a PayPal campaign, the image code must be manually updated to change the image displayed and restore the default image when the campaign is over.
• Enable PayPal Guest Checkout - If set to Yes, Magento customers who are not registered with PayPal have the ability to perform the payment without registering with PayPal. In this case, the customer needs to specify credit card information and billing address. After PayPal validates the credit card information, the customer can proceed to review the payment information and perform the actual payment. If the field is set to No, the customer must register with PayPal prior to proceeding to the payment.
• Billing Agreement Signup - Specify whether the customer can sign a billing agreement when there are no active billing agreements available in the customer account. The storeowner needs to apply to PayPal for enabling billing agreements feature. The Billing Agreement Signup parameter must be enabled only after PayPal confirms that billing agreements are enabled for your merchant account. Choose between the following options in the Billing Agreement Signup field:
  • Auto – the customer needs to sign a billing agreement.
  • Ask Customer – the customer can decide whether to sign a billing agreement.
  • Never – the customer cannot sign a billing agreement.

• 3D Secure Card Validation - Choose whether credit cards will be verified through the Centinel 3D Secure system. The 3D Secure functionality used for credit card verification must first be set up under System > Configuration > SALES > Payment Services > 3D Secure Credit Card Verification. In this case, credit card validation will be performed by the external Centinel® system when the PayPal Website Payments Pro payment method is selected. If the parameter is enabled, the following two fields become available:Severe 3D Secure Card Validation - Choose whether severe validation will be applied to credit cards by the Centinel system. Severe credit card validation removes the charge back liability on merchant.

Configuring API Integration to PayPal

API credentials must be specified in order to establish a connection to the PayPal API server. The Website Payments Pro Payflow Edition and Payflow Pro Gateway payment methods require the specific API credentials the merchant received when registering for a Payflow Pro merchant account.

To set up the API:

1. In the Magento Admin Panel, choose System→Configuration. Select the PayPal tab on the left. You'll see the following options:
2. In the API/Integration Setting panel, you can set the following values:
   • In the API Username, API Password, and API Signature fields, enter the API username, password, and signature provided by the PayPal payment system. API credentials can be located by clicking the API Credentials link in your PayPal merchant account.
   • Click the [Get Credentials from PayPal] button to be redirected to the PayPal site where you can get the API credentials for your merchant account. When in dev and testing phases, click the Sandbox Credentials button in your PayPal account to log on to your sandbox test account, and click the API Credentials link to acquire the necessary information.
   • Sandbox Mode - Indicate if you're in test or production mode for the PayPal payment system merchant account. The Sandbox mode helps testing the integration of Magento with the PayPal payment system. Transactions that are submitted while the account is in the Sandbox mode are not actually submitted to the credit card and electronic check processing networks, and credit card or bank accounts are not actually charged. Therefore, they do not have a valid transaction ID. Once you've finished testing the integration and website, the sandbox mode must be turned off.
   • API Uses Proxy - Indicate whether a proxy server will be used for establishing the connection between your Magento store and the PayPal payment system. This is used if the server has a firewall, and there’s no direct access to the PayPal server. You can use a third party server to relay the traffic.
     • If you select Yes, two additional fields for specifying the proxy host and port become available. In the Proxy Host and Proxy Port fields, specify the address of the proxy server and its port number to establish the connection between Magento and the PayPal payment system.

     • Header Image URL - Specify the URL for the image that will be displayed in the upper left part of the checkout page. The size of an image should not exceed 750 X 90 pixels.
