Why teams connect Klaviyo and Körber WMS
Bridge the tools people work in and the system the business runs on: real-time, two-way sync between Klaviyo and Körber WMS.
The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. Klaviyo is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.
Stacksync syncs Flows, Templates, Catalog Items, Tags in Klaviyo with Returns, Items, Inventory, Receipts / ASNs in Körber WMS bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.
Common use cases
- Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
- Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
- Mirror receiving and ASN data into procurement systems for inbound visibility
- Consolidate warehouse task and throughput data into a BI warehouse for operations reporting
Master data corrections travel
A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
Where Klaviyo faces customers and Körber WMS carries account records
Order, invoice, or account status from Körber WMS appears alongside the customer in Klaviyo, so front-line teams answer from live data.
Where Klaviyo collects payments: transactions post through
Payment events sync into Körber WMS as they occur, keeping the enterprise records current without manual entry.
What you can sync between Klaviyo and Körber WMS
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Klaviyo objects | Körber WMS objects | |
|---|---|---|
| Campaigns Email and SMS sends expose performance data for warehouse-based reporting. | Locations Bin and zone definitions scope inventory data during mapping. | |
| Flows Automation definitions and their engagement data sync outward for attribution. | Tasks Warehouse task data supports labor and throughput reporting. | |
| Templates Message templates are accessible via API for content management workflows. | Returns Return receipts flow back to commerce and ERP systems for refunds and restocking. | |
| Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. | Items Item definitions keep the WMS aligned with the ERP item master. | |
| Tags Organizational labels on campaigns, flows, and lists support reporting rollups. | Inventory On-hand quantities by location feed availability in order-taking systems. | |
| Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. | Receipts / ASNs Inbound notices and receipt confirmations sync with procurement systems. |

FAQ
Klaviyo and Körber WMS integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Klaviyo and Körber WMS: authenticate both systems, choose the objects to sync (such as Klaviyo's Campaigns and Flows), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Klaviyo: REST API compliant with the JSON:API specification. Authentication: OAuth 2.0 for apps or private API keys. Körber WMS: Varies by deployment; typically host-interface messages, file exchange, or vendor APIs via middleware. Authentication: Credentials issued per deployment. 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. Körber WMS: As is typical for large-scale WMS deployments, integration with ERP hosts is usually implemented through defined host interfaces and middleware rather than a single public SaaS API, so the integration surface varies by deployment. Stacksync's field mapping accounts for these differences between Klaviyo and Körber WMS without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Klaviyo and Körber WMS records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Klaviyo and Körber WMS connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Klaviyo–Körber WMS integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Klaviyo and Körber WMS. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
