Learn how to update your Zendesk integration, if you integrated Klaviyo and Zendesk before Klaviyo introduced OAuth for Zendesk and support for multiple Zendesk brands. It is important to update to gain the benefits of the new integration, and only our new integration will be updated going forward. 

On April 23, 2025, Klaviyo released OAuth for Zendesk and support for multi-brand Zendesk accounts. Connecting Zendesk and Klaviyo via OAuth provides a more secure authentication experience. You can now sync tickets from specified Zendesk brands to Klaviyo, and create tickets in Zendesk from inbound SMS messages under a specific Zendesk brand. 

If you have more than one brand set up under a Zendesk Enterprise account, syncing one Zendesk brand per Klaviyo account makes it easy to use your ticket data and organize your SMS conversations. 

Below, we’ll detail how to remove older Zendesk profiles from Klaviyo and update your integration.
