通过Google Checkout付费后如何返回我的网站？
我在我的网站点击Google Checkout按钮后进入Google Checkout付费，付完费后，我该如何返回我的网站呢？

请不吝赐教？

我用的是PHP 5.0。

1) <input type="hidden" name="checkout-flow-support.merchant-checkout-flow-support.edit-cart-url" value="http://www.example.com/edit "> 
  
by passing this field you can give link to edit your cart before checkout. 
  
2) <input type="hidden" name="checkout-flow-support.merchant-checkout-flow-support.continue-shopping-url" value="http://www.example.com/continue "> 
  
with this you can give link to your site after the transaction irrespectively of transaction result.
