The Google Checkout Sandbox is a test environment for running simulated transactions where no real money is traded. Using the sandbox environment requires using different API integration settings in your shop Payment Settings. Instead of using your Google Checkout API integration credentials, you’ll need to login to the Google Checkout Sandbox and use the integration credentials provided there.

Once logged into the sandbox environment, use the same setup process to copy your API credentials from Google Checkout to the shop Payment Settings screen:

  • Click the My Sales link at the top of the page
  • Select the Settings tab
  • Click Integration from the Profile menu on the left
  • You will need to copy your Google merchant ID, the Google merchant key and your Google Checkout account password (the one you used when creating your account) to your Google Checkout settings in shop.
