Why teams connect Klaviyo and MarkLogic

Mirror Klaviyo's data into MarkLogic so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Klaviyo through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in MarkLogic.

Stacksync mirrors Flows, Templates, Catalog Items, Tags from Klaviyo into Document Metadata & Properties, Databases & Forests, Users & Roles, Documents in MarkLogic and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Klaviyo, so the tool and the database never disagree.

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
  • Land document data in relational warehouses by reading TDE views as SQL rows.
  • Write updates from operational systems back into the document hub to keep the canonical record current.

Read Klaviyo with a query

Records from Klaviyo are ordinary rows in MarkLogic; join them, index them, and use them in application logic without touching the vendor API.

Automate Klaviyo from your codebase

Write to the synced tables in MarkLogic and Stacksync propagates the change into Klaviyo, replacing custom integration code.

React to changes as they happen

Updates in Klaviyo arrive as row changes in MarkLogic, so triggers, jobs, and services can respond in near real time.

What you can sync between Klaviyo and MarkLogic

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 MarkLogic objects
Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. TDE Views Relational projections of documents that let syncs read document data as SQL rows.
Tags Organizational labels on campaigns, flows, and lists support reporting rollups. Document Metadata & Properties Permissions, quality, and property fragments carried with each document.
Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Databases & Forests Storage units that define the scope and placement of synced content.
Lists Static audience memberships sync in from CRMs and forms for targeting. Users & Roles Security principals that govern what an integration credential can read or write.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Documents JSON and XML documents, the primary records read from and written to the database.
Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. Collections Named groupings used to scope which documents a sync reads or updates.
