Browsers display this type of activity in the network details of the inspection. You can view each JSON formatted request and the corresponding response of any administrative task.

1. Log in to your Kerio product's web administration
2. Enable the developer view in your browser
3. Perform the administrative task you want to build into your application
4. Locate the JSON requests and responses in your browser's developer view
