Zendesk Relationships API

The Zendesk Relationships API lets you model, create, and query links between data entities in Zendesk, spanning both standard resources (like users, organizations, and tickets) and Custom Objects. You define relationship types with explicit cardinality (one-to-one, one-to-many, or many-to-many), then create relationship records that connect specific instancesfor example, associating a customer with their devices, subscriptions, or locations, or tying tickets to assets or accounts.
