Description
When trying to add another webhook that uses the same Callback URL, the following error is returned:
A webhook of this type already exists with this callback.
To reproduce, add a webhook using a Callback URL. Then try adding another webhook using a different event but the same Callback URL.
Instead, it should be possible to use the same Callback URL for multiple events. It should also be possible to create webhooks for the same event with different Callback URLs.
It should only not be possible to create multiple webhooks that use BOTH the same Callback URL and the same Event.
Attached screenshot shows adding a 2nd webhook (for a different event), using the same URL.
