and How can I get notification from GoogleCheckout after payment ?

Answer 1

From Google Checkout Support:

The API callback URL you specify tells Google Checkout where to send notifications about new orders, order state changes, and other events. If you integrate your order processing system, you must specify a callback URL.

To add or edit your API callback URL:

1. Sign in to Google Checkout.
2. Click the Settings tab. Click Integration.
3. Enter your callback URL in the 'API callback URL' box.
4. Click Save.
