Enabling PayPal Express Checkout {#sa-enable-paypal-express-checkout}
=====================================================================

PayPal Express Checkout is not supported on a `Secure Acceptance` iframe integration.  
Contact `Cybersource` Customer Support to have your account configured for this feature. You must also create a PayPal business account. See [*PayPal Express Checkout Services Using Alternative Payment Services Simple Order API*](https://docs.cybersource.com/content/dam/new-documentation/documentation/en/altpay-paypal-express/developer/all/so/altpay-paypalexpress-so.pdf "").  
Add the PayPal Express Checkout payment method to your checkout page and redirect the customer to their PayPal account login. When logged in to their PayPal account they can review orders and edit shipping or payment details before completing transactions.

1. In the left navigation panel, choose Payment Configuration \> `Secure Acceptance` Settings. The `Secure Acceptance` Settings page appears.
2. Choose a profile. The General Settings page appears.
3. Click Payment Settings. The Payment Settings page appears.
4. Check Enable PayPal Express Checkout.
5. Check Allow customers to select or edit their shipping address within PayPal to allow customers to edit the shipping address details that they provided in the transaction request to `Secure Acceptance`. Customers select a new address or edit the address when they are logged in to their PayPal account.
6. When the transaction type is authorization, check one of these options:
   * Request a PayPal authorization and include the authorization response values in the response---check this option to create and authorize the PayPal order. The customer funds are not captured using this option. You must request a PayPal capture; see the PayPal guide. If the transaction type is ` sale `, ` Secure Acceptance ` authorizes and captures the customer funds.
   * Request a PayPal order setup and include the order setup response values in the response---check this option to create the PayPal order. The customer funds are not authorized or captured using this option. You must request a PayPal authorization followed by a PayPal capture request; see the PayPal guide. If the transaction type is ` sale `, ` Secure Acceptance ` authorizes and captures the customer funds.
7. Click Save.
