Use the maxFileAgeHours parameter in the Data Import API operation to
prevent files from being imported if they weren’t created or modified within a specified period.
When a developer includes this parameter in a request, Marketing Cloud Engagement checks the
modified date of the file. If the difference between the modified date and current system time
exceeds the maximum number of hours, the import doesn’t run. The system normalizes timestamps so
that different time zones don’t impact the file age calculation.
Where: This change applies to all Marketing Cloud Engagement editions with API access.
