# Use PayPal Express

Use the **getPayPalExpressCheckoutRedirectURL** method to retrieve the `RedirectURL` by sending an order object with PAYPAL\_EXPRESS payment method.

## Workflow

1. Authentication via login API method.
2. Retrieve PayPal redirect URL. When you retrieve the PayPal redirect URL, apart from the token you will also receive 2 parameters that are encoded: `billingDetails` and `deliveryDetails`. These have to be base64\_decoded and the information should be used in the **placeOrder** API call (email, billing address etc.).
3. Place the order with PayPal Express using the token sent by PayPal.
