How to find total number of topics in a particular board

Hi Parvez_AL ,

If you are looking for count of topics, you can try this - /restapi/vc/boards/id/[id] /messages/count.

If you would like to use V2 API, you can try this sample: 

SELECT id, topics.count(*) FROM boards WHERE topics.count(*) > 1

Refer https://devdocportal.lithium.com/t5/Community-API-v2-Reference/bd-p/restv2docs?section=commv2&collection=boards for further details.

Thanks,
Srujana.
