What does the `dw.expiration` setting do in Salesforce Commerce Cloud?

The dw.expiration setting in Salesforce Commerce Cloud is utilized to set expiration dates for campaigns or content. This functionality allows developers and marketers to define a specific timeframe during which promotions, discounts, or other campaign-related content are relevant and active. Once the expiration date is reached, the system ensures that the associated content is no longer displayed or applicable, effectively managing the lifecycle of marketing efforts and ensuring that users only see offers that are currently valid.

This temporal control helps businesses implement timely marketing strategies and enhance the shopping experience by preventing customers from viewing outdated promotions or offers. The ability to set expiration dates is crucial for managing dynamic content and aligning promotional activity with business goals.
