Application Interface Framework (AIF) has a standardized and pre-enabled SFTP connector. You can use the SFTP connector to introduce new CSV files into CDP and add new attributes into the existing data entities such as Customer, Transaction, Transaction Item, Product, Product Category, and Event. The pre-enabled SFTP connector works seamlessly with your daily refresh cycle and eliminates the need for a separate scheduling. You can use pass-through values with a preset placeholder structure in the data model that makes the custom attributes available for immediate use.
