Get Call Transcript API Permission?

I am trying to use the call Transcript API and I am not able to complete the request. I get a 404 error saying "not found or cannot be accessed due to insufficient permissions". The API key is corrent and I am trying multiple different call IDs with the same result. I have maxed all the permissions in the admin portal for this api key. Is there a hidden setting to turn on or does support have to turn it on?
