Setting up a Google Checkout merchant account

To be able to use Google Checkout at your store, you will need a Google Checkout merchant account. If you have not yet signed up for one, you can do so at this page. Sign in to your merchant account to obtain your Merchant ID and Merchant Key. These values will be used by your store to encode order information before it is submitted to Google Checkout.

You will need to specify both of these values in the admin menu on the Google Checkout module configuration page (Make sure you use these values only in Live mode. For Test mode, the Merchant ID/Merchant Key pair needs to be obtained separately. See the section 'Setting up test accounts in Google Checkout Sandbox service' in this chapter). In your merchant account, your Merchant ID is located on the 'Settings' tab under 'Primary contact information' header, Merchant Key - in the 'Integration' section ('Settings' tab->'Integration') under 'Account information' header.
