The AssociationDelete event fires when an association type definition is permanently removed from an account. Deleting an association type also removes the ability to create new relations of that type. Supports contact-to-contact, contact-to-custom object, and custom object-to-custom object relationship types. Use this event to clean up dependent configurations in external systems or alert integrations that a relationship type they relied on no longer exists.

associationType | string | Whether the association was "USER_DEFINED" or system-defined |
