How to pass user agent string for iPad through API


I have ran my test on iPad emulation through GUI but not getting correct result, it was showing iPhone emulation result (navigation bar in bottom) instead of iPad result (web page without navigation bar), also i have checked specific services in waterfall and got those services which is belongs to iPhone only so I have tried with custom user string for iPad and got the correct result so might be issue with iPad Emulation on public WPT.
Can anyone please let me know how to pass custom user string in API or what parameter I need to pass in API URL.
