No, a single PDP instance is scoped to a ​*single environment*​. (1) There are three types of API keys in Permit.io: • ​*Environment API Keys*​ – can access a single environment. Only this type of API key can be used by the PDP container. • ​*Project API Keys*​ – can access a single project and all environments within it. • ​*Organization API Keys*​ – can act on your entire Permit workspace. The PDP container specifically requires an ​*Environment API Key*​, which means each PDP is configured for one specific environment. If you need to serve authorization checks for multiple environments or projects, you would need to run ​*separate PDP instances*​, each configured with its own Environment API Key. For multi-tenant scenarios within a single environment, tenants are handled as first-class citizens within that environment—users and resources are scoped to tenants, but the policy schema remains shared across tenants within the same environment.
