Get access to API communication-preferences/v3/resubscribe
I am trying to use the API at https://api.hubapi.com/communication-preferences/v3/resubscribe but when I try to use it i get a response saying "The scope needed for this API call isn't available for public use. If you have questions, contact support or post in our developer forum."
How can I get access to this private scope so we can use this API call?
