Jira dynamic webhooks restrictions

[Daniel Radezky]

I have a few questions about Jira dynamic webhooks restrictions. So, according to the documentation I took from here https://developer.atlassian.com/cloud/jira/platform/webhooks "A maximum of 100 webhooks per app per tenant is allowed for a Connect app. For an OAuth 2.0 app, the limit is 5 webhooks per app per user on a tenant."

First of all, what does tenant mean here? Is it a jira site?

Secondly, in the Register dynamic webhooks endpoint it's mentioned that only one URL is allowed to be registered. Where does this restriction come from? And what should I do if I need to send webhook events to multiple destinations? Why is it allowed to create more than one dynamic webhook but not more than one url to send events to?
