Is this what you are asking for,
This is the API that's being called through traccar when requesting reports,
Tried directly pasting this to the browser but still it shows less data than the web application.
http://52.203.222.155:8082/api/reports/route?_dc=1637041098383&deviceId=123&type=allEvents&from=2021-11-14T18%3A30%3A00.000Z&to=2021-11-15T18%3A30%3A00.000Z&daily=false&page=1&start=0&limit=25
I already see that the parameters are different, which means it's not the same report you tried earlier.
It return different data if you call it directly? That makes no sense to me. Please provide a screen recording showing both web app request, data etc and calling it directly.
I asked for screenshot of the network request that Traccar web app makes.
