I am using okta event web hooks to capture certain events for auditing. But there is no support for comma separated list of endpoints where the events can be delivered. Since there is a hard limit of 10 active web hooks per okta org, creating multiple web hooks for different environments (lab, integration, sandbox) of my application is quite expensive option as I am using 3 web hooks for just one application. If support for multiple urls is given, then I can achieve my purpose with a single event web hook.
Also for testing purpose if urls like http://localhost:8080 is enabled , then it will be of great help for testing from local machines.
