When a webhook for issues is triggered, it should also return the
resource URL, and the action that was performed (ie: Was it reopened,
updated, opened or closed)
The goal of suych refactoring is to get rid of observers.
Its much easier to test and code when object creation and all other
related actions done in one class instead of splited across observers,
callbacks etc.
