Dynamic variable in webhook path changes URL

The idea is:

I want the URL to remain unchanged when I add a dynamic variable to a webhook path. Right now, a UUID is added between /webhook and my path.

My use case:

I want to create a CRUD API endpoint /article. I can not define the endpoints GET /article/:id, PATCH /article/:id and DELETE /article/:id.

Path: /article => URL http://localhost:5678/webhook/article
Path: /article/:id => URL http://localhost:5678/webhook/763f02b0-1a74-46ea-8a27-a48b56c554e8/article/:id
