 GlobalContextEntries must be in a healthy state (i.e., there is a response received from the remote endpoint) in order for the policies which reference them to be considered healthy. A GlobalContextEntry which is in a `not ready` state will cause any/all referenced policies to also be in a similar state and therefore will not be processed. Creation of a policy referencing a GlobalContextEntry which either does not exist or is not ready will print a warning notifying users.

-## Default
-Default is an optional arbitrary JSON object that the context may take if the apiCall returns an error. Default value can also used in case of a server error.
+#### Default values for API calls
+In the case where the api server returns an error, `default` can be used to provide a fallback value for the api call context entry. The following example shows how to add default value to context entries
 
 For example, the policy below uses `default` values to validate: 
 ```yaml
-apiVersion: kyverno.io/v1
-kind: ClusterPolicy
-metadata:
-  name: default
-spec:
-  rules:
-  - name: default-apicall
-    match:

-      - resources:
-          kinds:
-          - Pod
-          operations:
-          - CREATE

     context:
-    - name: testString
+    - name: currentnamespace
       apiCall:
-        urlPath: "/api/v1/namespaces/{{ request.namespace }}/invalid"
+        urlPath: "/api/v1/namespaces/{{ request.namespace }}"

-        jmesPath: metadata.resourceVersion
-        default: 1     
-    validate:
-      deny:
-        conditions:
-          all:
