Place a New Order using the Alternative Method

The alternative method of posting Checkout API requests contains the following steps:

  1. The Merchant web page displays a Google Checkout button. The button is contained in a form that submits to the merchant's server.
  2. When the customer clicks the Google Checkout button, the merchant's server generates the <checkout-shopping-cart> XML and posts the shopping cart directly to the Google Checkout server.
  3. The Google Checkout server responds to the merchant's request with a <checkout-redirect> XML response, which contains a <redirect-url>.
  4. The Merchant returns an HTTP 302 redirect to the customer's browser.
  5. The customer's browser follows the redirect, bringing the customer to the Google Checkout order page.
