This topic describes how to install and use the PayPal payment provider, one of several payment solutions available for Episerver Commerce.

Apps folder

In Episerver Commerce 7.5, the Apps folder is located in the Episerver Commerce Manager Shared Files Folder, typically C:\EPiServer\<YourCommerceManagerSite>\eCommerceFramework\5.3\Shared.

If your Commerce Manager site is updated to the latest version via NuGet, the Apps folder should be located in the wwwroot folder, typically E:\ EPiServer \<YourCommerceManagerSite>\wwwroot\Apps.

Refer to this Apps folder as your corresponding path for the Apps folder mentioned below.

Configuring the PayPal HashKey (optional)

The communication with PayPal uses a private hash key to ensure security in the communication. This private hash key will be used to create secure hash keys, which appends to an accept URL and a cancel URL. The information about accept URL and cancel URL is sent to PayPal using HTTPS, so these keys will not be exposed.

When PayPal redirects a user to those URLs, the keys are used to verify that the request comes from PayPal only, since only PayPal knows about the keys.

You can configure this hash key in the application settings configuration section under the key “PayPalHashKey”.

Using PayPal

When you have deployed the files and configured the PayPal Payment module on your Episerver Commerce website, you should have a PayPal option in your checkout procedure.

  1. Select PayPal as payment method on the Payment Options page during check out.
  2. When you click Place Order on the order confirmation page, you are redirected to PayPal.com to approve the payment.
  3. You can see the shipping and billing addresses entered in the checkout procedure, during which you can change these addresses.
  4. When you have finalized the approval process, you are redirected to the “Your Orders” page previously configured.
        

Note: PayPal.com checks the address (billing and shipping) very carefully. If you use a US address to test, use the correct and complete one with ZIP code, State, and City, otherwise the precheck with PayPal API will fail and you cannot complete the payment.
