Event Hooks are outbound calls from Okta that trigger process flows within your own software systems. They are sent when specific events occur in your org, and they deliver information about the event. Unlike Inline Hooks, event hooks are asynchronous and do not offer a way to execute the Okta process flow. After sending the call, the Okta process flow continues without waiting for a response from the called service.
To set up an Event Hook, you need to implement a web service with an Internet-accessible endpoint. It is your responsibility to arrange hosting of your code on a system that is external to Okta. Okta defines the REST API contract for the requests it sends to your custom code, as well as for the responses your custom code can send back.
