Klaviyo to ZoomInfo integration — real-time data sync

Yes. Stacksync provides a managed, real-time integration between Klaviyo and ZoomInfo — ZoomInfo is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.

On the Klaviyo side: Flows, Templates, Catalog Items, Tags, plus custom fields where Klaviyo exposes them. On the ZoomInfo side: Company Profiles, Contact Profiles, Intent Signals, Scoops. Stacksync auto-detects both schemas and converts types between the two systems.

ZoomInfo is a read-only source, so this integration runs one-way: Stacksync reads from ZoomInfo in real time and delivers into Klaviyo. Field mapping and monitoring work the same as for two-way pairs.

Common patterns for Klaviyo and ZoomInfo: Where Klaviyo processes payments; Where Klaviyo can store CRM context: fields kept current; Where Klaviyo runs outreach. Charges, refunds, and subscription changes appear on the account in ZoomInfo, so revenue context lives with the relationship.

Klaviyo: REST API compliant with the JSON:API specification. Authentication: OAuth 2.0 for apps or private API keys. ZoomInfo: REST API organized around search and enrich endpoints. Authentication: API credentials exchanged for a short-lived JWT. Stacksync manages authentication, retries, and rate limits on both sides.

Klaviyo: Profiles accept arbitrary custom properties, and events are append-only records tied to named metrics, which together form the segmentation model external data is synced into. ZoomInfo: Intent data is delivered as company-level topic scores rather than person-level events, which shapes how it maps onto CRM records. Stacksync's field mapping accounts for these differences between Klaviyo and ZoomInfo without custom code.
