While creating an board through api, it is by default creating a item type board but i want to create a Campaign type board, is there any way if yes then tell or how to retrieve template_id of a campaign type board
Hey @Ashutosh
Bill here from monday.com 
If you were referring to the board’s item terminology (“New Campaign” vs “New Item”), then this can be set within the platform only and can’t be done via the API.
I hope this helps.
Cheers,
Bill
