Connect nopCommerce with Klaviyo for Smarter Customer Engagement and Reliable Data Synchronization The nopStation Klaviyo Integration Suite Plugin is designed to connect nopCommerce stores with Klaviyo and synchronize customer profiles, newsletter consent, product catalogs, and ecommerce activity. It helps merchants keep important store data available in Klaviyo so they can build richer customer profiles, create targeted segments, build audiences from their own customer roles and discounts, and power marketing automations.

The plugin provides a secure, store-scoped integration with Klaviyo and supports controlled synchronization of customer, catalog, and ecommerce data. It offers independent subscriber and historical-order destination lists, consent-aware newsletter workflows, audience building from nopCommerce customer roles and discounts, historical data transfer, and background processing with retry and failure-handling capabilities.
Instead of processing synchronization directly during customer or store activities, the plugin uses a durable queue and background processing system. This allows synchronization work to be handled reliably, monitored from the nopCommerce administration area through a dedicated synchronization run grid and store dashboard, and retried when eligible operations encounter temporary failures.

Feature Overview
- Secure Klaviyo Connection Connect your nopCommerce store to Klaviyo using a secure private API key. The key is held in encrypted storage and only a fixed mask is returned after saving, so the saved value is never sent back to the browser.
- Independent Subscriber & Historical-Order Lists Refresh the available Klaviyo lists, create new lists directly from the administration area, and select the subscriber destination list and the historical-order destination list independently.
- Customer Profile Synchronization Synchronize customer profiles from nopCommerce to Klaviyo using minimized customer information. Email addresses are normalized, phone numbers can optionally be mapped to E.164 format, and namespaced nopCommerce customer and store identifiers maintain a clear, stable customer identity across stores.
- Consent-Aware Newsletter Synchronization nopCommerce newsletter events are handled automatically through durable subscribe and unsubscribe operations, and a live newsletter signup is sent with historical_import=false.
- Audience Building from Roles and Discounts Create a Klaviyo list from a selected nopCommerce customer role, or create a Klaviyo segment from supported customer-role, spent-amount, and product discount requirements.
- Product Catalog Synchronization Synchronize nopCommerce categories, products, and product variants with Klaviyo. Store-aware publication and availability handling, stable external identifiers, and content hashes keep catalog updates consistent and idempotent, so repeated runs do not create duplicate catalog records.
- Ecommerce & Onsite Event Tracking Send the store activities that matter most to Klaviyo: Active on Site, Viewed Product, Added to Cart, Started Checkout, Placed Order, Ordered Product, Fulfilled Order, Canceled Order, and Refunded Order.
- Multi-Store Support Configure the Klaviyo integration separately for each nopCommerce store. Credentials, both destination lists, synchronization events, run history, and queued work all remain store-scoped, which keeps multi-store environments cleanly isolated.
