What are you trying to accomplish and what version of Jive? Have you checked out the webohooks service?
Webhooks are fundamentally HTTP callbacks. In a nutshell, webhooks allows your system to get notified whenever some state you are interested in changes in a remote system (eg. Jive), avoiding the need to poll. It's a way to integrate systems based on the observer pattern, allowing your system to subscribe to events and get callback notifications.
External systems may register for and manage webhooks through this webservice. Jive will invoke an endpoint on the external system if the conditions for triggering the hook are met. Depending on the events field of the registered, Jive will send content or system webhook activity object notifications to the webhook endpoint.
