I noticed I was able to log into the Marketplace from within the owncloud appliance, the part where it connects to Marketplace and you can install apps.
How do I log out? I thought it was a web browser cache setting, but it appears to be hard keys into the appliance.
The “Clear cache” doesn’t seem to be related to it, I did try.
The API key is required to install and update apps from the market app. Without it, you have to access your enterprise account and download the apps from there, extract them on your server and activate them.
The purpose is to link your enterprise account to the marketplace.
