Depending on the connector (data source) you have set up, you will receive data of different types.

Data such as orders made in your Shopify store will be received in real-time.

However, some information needs to be synchronized periodically, and depending on the data volume, it may require more time. This is the case with lists in Klaviyo.

From the Data Sources section, hover over the data source, and you will be able to see the details of all the synchronizations that are performed for each connector. If desired, you can force a synchronization to update any data that is not fully up to date.
