# Relation Delete | Webhook Events

> Fires when an existing relation (record-level link) between two object records is removed.

The `RelationDelete` event fires whenever an existing record-level link between two objects is removed. The payload identifies both sides of the now-deleted relationship along with the governing association definition. Use this event to remove corresponding edges from external graph databases, update denormalized data, or trigger cleanup workflows when records are unlinked.
