Whose keys are the keys that are already in the System Keyvault? That seems kind of weird. Are those other people’s keys, or are those my keys? If I try to export them I just get another empty.keys file. I didn’t try deleting any.
The dev.apiant.com system is shared by many people. It is used for training and development.
If you are using the Admin Console to view the system keyvault, that contains all the publicly available API keys for the system.
Do not delete or change any existing API keys from the Admin Console!
