Is the Contact ID unique between all HubSpot accounts?
I know that there is this endpoint below:
that retrieves a contact object identified by the given contactId in a specific HubSpot account (identified by the provided access token).
If I send a request to the same endpoint but changing the HubSpot account (which means a different access token) there is the possibility of retrieving another contact object (from a different account but with the same id)?
I ask that because my main concern is: The contactId is unique between ALL HubSpot accounts, or it is unique only considering a given HubSpot account?
