Klaviyo currently supports only one integration of any type within a single Klaviyo account.
If you have more than one ecommerce store of the same type, you will need to create a Klaviyo account for each store. If you have more than one store, and each is supported by a different platform, it is technically possible to integrate all stores with the same Klaviyo account. However, we highly recommend against this option in order to streamline data analysis and prevent confusion amongst metrics with flows and segments. We don’t provide a way to separate stores within a single Klaviyo account.
If you are using Magento, it’s possible to integrate a Magento server that has multiple stores on it. When you do this, we will sync all profiles and order data from each store into your account. Additionally, we will sync “Magento Store Name” and “Magento Website ID” properties for each profile created so you can identify the store where a profile belongs. Then, you can configure our extension on a site-by-site level to pick which list to add subscribers to, and you can filter flows and segments, using the Magento store name to separate flows between stores.
