Merchant ID and Key
Your Merchant ID is a unique, numeric code that Google Checkout has assigned to your business.
Your Merchant Key is a unique code that helps secure your communications with Google. Both you and Google will use this key to authenticate and verify the integrity of any messages we exchange. You'll also need your key to use your pre-integrated shopping cart or custom-built shopping cart with Google Checkout.
