+## How to send integer or boolean parameters to API Server
+
+If you want to send an integer or boolean parameter to the API server, you will see that the data type in API function is `int *`, e.g.
+
+```c
+// list or watch objects of kind Pod
+//
+v1_pod_list_t* CoreV1API_listNamespacedPod(apiClient_t *apiClient, 
+ char *_namespace, 
+ char *pretty, 
+ int *allowWatchBookmarks, /* <-- here */
+ char *_continue, 
+ char *fieldSelector, 
+ char *labelSelector, 
+ int *limit, /* <-- here */
+ char *resourceVersion, 
+ char *resourceVersionMatch, 
+ int *sendInitialEvents, /* <-- here */
+ int *timeoutSeconds, /* <-- here */
+ int *watch); /* <-- here */
+```
+
+For example we can send `timeoutSeconds` and `watch` using the following usage:
+
+```c
+int timeoutSeconds = 30;
+int watch = 1;
+pod_list = CoreV1API_listNamespacedPod(apiClient, "default", /*namespace */
+ NULL, /* pretty */
+ NULL, /* allowWatchBookmarks */
+ NULL, /* continue */
+ NULL, /* fieldSelector */
+ NULL, /* labelSelector */
+ NULL, /* limit */
+ NULL, /* resourceVersion */
+ NULL, /* resourceVersionMatch */
+ NULL, /* sendInitialEvents */
+ &timeoutSeconds, /* timeoutSeconds */
+ &watch /* watch */
+);
+```
+
+Setting the parameter to `NULL` means not to send the parameter to the API Server, and the API Server will use the default value for this parameter.

 ## Aggregated APIs and CRD-based APIs
 
 If you want to implement a client for aggregated APIs (such as the metrics server API `apis/metrics.k8s.io` ) or CRD-based APIs, use the [generic client](./kubernetes/src/generic.c). See [example](./examples/generic/main.c).
