¿ How to obtain data from the units?

¿How can I get this unit data, date and time, longitude, latitude, plate, model and color. I do not know whether to use item search by ID or article search by property, I was checking the manuals and I see that searches are done through parameters and IDs and flags, but I do need the search to be general and search me more than one unit on several occasions as I do in the part where it asks for the example ID;

https://hst-api.wialon.com/wialon/ajax. … _item&
    params={
        "id":34868,
        "flags":1025
    }&sid=<your_sid>

What would you put in this case or is it valid to put it like this:

params={
        "id":"",
        "flags":1025
    }&sid=<your_sid>

help me please.
