cURL showing error "Not Authorized/Not Authenticated"

Hi.
I am new here. I tried to use the CURL example of modifying a column in my board.
I copied the V2 API Token from my Admin Profile and pasted in the authorization tag.

My Code:

curl -X POST -H “Content-Type:application/json” -H “Authorization:XXXXXXX” “https://api.monday.com/v2” -d ‘{“query”:“mutation{change_column_value(item_id:323796391, board_id:321744566, column_id: “Customer”, value:”\\“Hello world\\”“){name}}”}’

I am receiving the below error message:
