 ### Filter on JSON Array
 `int` type filters support sending the values as an array in the URL Query parameters. For example `?filters[id]=[1,2]`. This is a way to keep payloads smaller for GET requests. When URI encoded this will become `filters%5Bid%5D=%5B1,2%5D` which is much smaller the standard format of `filters%5Bid%5D%5B%5D=1&&filters%5Bid%5D%5B%5D=2`.
