Overview
Integrating Shipping Module
The PayPal shipping module presents shipping details to a buyer during the PayPal flow. The merchant has several ways to determine how shipping addresses and shipping options are handled. The server-side shipping callbacks allow you to update the shipping and order amount information as buyers make changes on the PayPal review page.
Buyers can use the shipping module to specify the shipping address and shipping options on the PayPal paysheet. PayPal sends a callback to the merchant's URL with the updated shipping information (buyer’s address, state, city, country code, and zip code) using the server-side shipping callbacks. In response, the merchant can send PayPal the shipping options and updated order cost amounts.
To include Shipping Module in your integration, set the server side shipping callback URL as shown below. For more information, see the Integration code samples section, below.
