# Vikunja: Webhooks and link shares survive every revocation path, so a removed collaborator keeps a live feed in code.vikunja.io/api

Vikunja's API keeps webhooks and link shares active after the sharing user is removed or the share is revoked through the normal paths. A former collaborator can keep receiving task data or accessing the shared project feed.

_Summary, check and fix written by a model from the sources; labelled as such._
