3554328 - How product recommendations are influenced by the sales data upload method?

At SAP Emarsys Help: Preparing your sales data file, it is mentioned that:

• Sales data uploaded through the API does influence product recommendations, while sales data uploaded through Smart Insight SFTP does not. The method itself makes a difference.

However, it is not clear how exactly the recommendations are affected by the upload method. This is important for scenarios where the purchases are not registered via web extend, for example.
