The Cart simulation endpoint now includes a new optional parameter allowedOutdatedData to give you more control over data freshness and performance trade-offs.

The allowedOutdatedData parameter is an array of strings that allows you to specify which data types can use cached or slightly outdated information during cart simulation, potentially improving response times for cart operations. The possible data that can be skipped are inventoryData, deliveryData, promotionData, paymentData, and taxData.

In order to provide more flexibility and improve performance for cart simulations, we added the allowedOutdatedData parameter. This enhancement allows developers to optimize their checkout experience by choosing when to prioritize speed over real-time data accuracy, particularly useful for high-traffic scenarios where cart simulation performance is critical.

This is an optional parameter, so no action is required. Existing implementations will continue to work without any changes.

To use this new parameter in your cart simulations, include allowedOutdatedData in your request body when calling the Cart Simulation endpoint. Refer to the Cart simulation API reference for detailed information about the parameter's accepted values and behavior.
