checkRevisedItems will return a list called itemIDs inside the apiResponse - This list is all the items that need getItems again instead of needlessly pulling the response from the api into a variable and applying a dict there, apply directly to the api call switchDateRange will now output a dict containing a range ending today if no arguments are given
