How to find total number of topics in a particular board

Hi Parshant & srujanayeruvaka ,

I used this https://community.lithium.com/restapi/vc/boards/id/[id]/topics/count

and got a number. Now i see a significant difference in the number from the number that i get from Community Admin Advanced metrics. So not sure which number to trust . There is a difference of about 500 topics. Any suggestions which one i should got for
