A workspace is your Hopae Connect account — it corresponds 1:1 with your Console organization. There is no separate “create workspace” API call: signing up for Hopae Connect through the Console provisions your workspace automatically. Inside a workspace you manage one or more Apps (typically one per end-customer or per product surface), each of which can activate any combination of eID providers.
Create and manage keys in the Console under Developers → Workspace API Keys. Keys are environment-specific (sandbox, production) and begin with sk_workspace_.
