Does anyone know the correct request syntax to debug_token ?

Hello all,

Going mad trying yo get the correct API syntax to issue a debug_token.

FB.request (“debug_token”,“GET”, object)

What is the correct syntax for object ?

I know i need both “input_token” and “access_token”, but have tried a number of syntax attempts but can’t get any to work.

Attempted these where input_token and access_token are strings.

    object = {fields=“input_token=” … input_token … “,access_token=” … access_token}

    object = {fields=“input_token=”" … input_token … “”,access_token="" … access_token … “”"}

    object = {fields=“input_token=” … input_token … “&access_token=” … access_token}

    object = {fields=“input_token=”" … input_token … “”&access_token="" … access_token … “”"}

Plus numerous others.

Thanks
