Hi,
As of now, it is not possible to change the sort order, it is returning the dataset in ascending order.
I suppose what you could do is to
Get the transactions that have been modified since your last request with a page size of 1
Check the totalCount in the metaData returned
If the count is one, this is the only document that has changed and nothing else would be needed
If it is higher than one, request the last page and use that date
Then again, if the only need that you have is to check if they have had any new transactions since the last time you checked, you could always just check the endpoint everyday and update the datetime parameter, if the returned set is not empty they have posted to the journal.
