Hi guys, having a bit issue over something really stupid here. My merchant key is not shown in my google checkout account. I got a response from Google's semi robotic help to say as I was a Google developer I needed to register the checkout with that account. Which I had. They tell me it is located in the 'Integration' section under 'settings'. My account, alas, has no integration section under settings.... So Im still waiting a couple of days for a response from Google as to where I should find the hidden key. Has anyone else had this problem and has an answer? Thanks
Resolved, the Google account was connected with a Google Play Store Account so the Checkout didnt issue a key because it was assumed the store would be the only route for payments.
