APIUnavailable when using Events API

Hello,

I have the Support Suite (Professional) with Productivity Pack add-on.

all the APIs are working for me except the Events API.

I've tried both:

POST myaccount.zendesk.com/api/v2/users/{userId}/events

POST myaccount.zendesk.com/api/v2/user_profiles/events

It always returns HTTP 403

Client error: `POST https://viddyoze.zendesk.com/api/v2/users/XXXXXXXX/events` resulted in a `403 Forbidden` response: {"errors":[{"id":"999999999999-DUB","code":"APIUnavailable","title":"API is unavailable for this account"}]}
