Webhooks and Notifications

Hey guys, I would like to ask a question about webhooks and notifications. My software will integrate with an X software, this X software has an area where it is possible to paste a webhook url so that event notifications are sent, the question I have is the following, when I create a detect workflow api data, that url that appears to me, anyone from my application can copy it and put it in software X, that notifications will be sent to all users of my software who put the url in software x? Sorry if it got VERY confusing, but we can open the discussion to other fields and give more examples. Thank you for your help!
