Webhook creating multiple events at once

I have a webhook defined in my project. The system does not allow me to review my settings, that is one problem. The webhook as setup to trigger an external CI build. I get multiple triggers. In fact I get a trigger about every 10 seconds starting when the source of the trigger’s build is pending and never stopping.

If the source of the trigger is waiting for a reply from the destination, I want to turn off this feature. The retry period is set way to short. Or can I set the retry myself. If not we need this feature to stop buildup up of needless builds.
