Hi PerBonomi ,
what about using an endpoint and APIv1 as an alternative approach?
You can add your IDs as a Freemarker sequence and loop over this list. For each list item you can send an APIv1 request to get the last_visit_time of the current ID.
While looping you can create/build your final response object, which contains a key/value structure with ID/last_visit_time.
Looping through big lists and sending API request for each list item is a costly operation and you'll have to check the performance of your instance etc.
