account attempt buyer digital financial google-checkout integration key links merchant page products profile required sell seller service settings

I have a merchant account with Google Checkout. I would like to use your service to sell digital products, however, when I attempt to get the required merchant Key I cannot find the integration page.When I go to settings there are 2 links: profile and financial but nothing in regards to integration.

That means that you don't have a Google Checkout Seller account, just a Google Checkout buyer account. Please see https://checkout.google.com/sell/
