Retrieve API Key (Admin API)

 
       ID of the actor that created the object.
 
-    - `type: string`
+    - `type: "service_account" or "user"`
 
       Type of the actor that created the object.
 
+      - `"service_account"`
+
+      - `"user"`
+
   - `expires_at: string or null`
 
     RFC 3339 datetime string indicating when the API Key expires, or `null` if it never expires.

 
     Partially redacted hint for the API key.
 
-  - `principal: object or null`
+  - `principal: object or object or null`
 
-    The ID and type of the principal the API key acts as, or `null` if the key is not bound to a principal.
+    The principal the API key acts as (a User or a Service Account), or `null` if the API key is not bound to a principal.
 
-    - `id: string`
+    - `UserActor object`
 
-      ID of the principal the API key acts as: a User ID (`user_...`) when the type is `user`, or a Service Account ID (`svac_...`) when the type is `service_account`.
+      - `type: "user_actor"`
 
-    - `type: "service_account" or "user"`
+        Principal type. Always `"user_actor"` for a User.
 
-      Type of the principal the API key acts as.
+        default: user_actor
 
-      - `"service_account"`
+      - `user_id: string`
 
-      - `"user"`
+        ID of the User the API key acts as.
 
+    - `ServiceAccountActor object`
+
+      - `service_account_id: string`
+
+        ID of the Service Account the API key acts as.
+
+      - `type: "service_account_actor"`
+
+        Principal type. Always `"service_account_actor"` for a Service Account.
+
+        default: service_account_actor
+
+  - `scope: object or object`
+
+    Where the API key belongs: its Workspace (`{"type": "workspace", "workspace_id": "wrkspc_..."}`, with the Workspace's real ID even when it is the organization's default Workspace), or the organization (`{"type": "organization"}`) for a principal-bound API key that has no Workspace.
+
+    - `Organization object`
+
+      - `type: "organization"`
+
+        Scope type. Always `"organization"`: the API key has no Workspace. Only a principal-bound API key can have this scope.
+
+        default: organization
+
+    - `Workspace object`
+
+      - `type: "workspace"`
+
+        Scope type. Always `"workspace"`: the API key belongs to one Workspace.
+
+        default: workspace
+
+      - `workspace_id: string`
+
+        ID of the Workspace the API key belongs to. Unlike the deprecated top-level `workspace_id`, this is the Workspace's real ID even for the organization's default Workspace.
+
   - `status: "active" or "archived" or "expired" or "inactive"`
 
     Status of the API key.

 
   - `workspace_id: string or null`
 
-    ID of the Workspace associated with the API key, or `null` if the API key belongs to the default Workspace.
+    **Deprecated**: Use `scope` instead. `workspace_id` is `null` both for an API key in the default Workspace and for a principal-bound API key that has no Workspace.
 
+    Deprecated: use `scope` instead. ID of the Workspace associated with the API key, or `null` if the API key belongs to the default Workspace. Also `null` for a principal-bound API key that has no Workspace; `scope` tells the two apart.
