Which all paraments can I use to capture city information. like I want to groupby by cities to find my orders at a city level. Any alternative to IP based city.

Hi @Ankit Navinkumar Jain 

Is the Region property being captured for most events? You can use this as a proxy if this is getting resolved accurately by MaxMind.

One alternative is to research on any other provider which gives hyperlocalized resolution of geoIP in India. If this service looks accurate enough for your use case, you can try sending an Identify API call with the resolved City,Region, IP address from your backend. You also need to change your SDK settings to stop collection of the IP address on client events since that can overwrite these fields.
