TASKS_PLATFORM_ONLY: the organization uses a self-serve Sessionboard product; Tasks are part of Sessionboard Platform.
SCOPE_REQUIRED: the key lacks read:tasks (reads) or write:tasks (writes). Legacy keys with no scopes can read but not write.
ORG_WIDE_TOKEN_REQUIRED: the key is restricted to particular events; Tasks need a key without an event restriction.
FORBIDDEN: the key's user can read this task but not change it (only the assignee, the creator, a follower or an admin can; only the creator or an admin can delete), or cannot use Tasks (reviewers and portal users).
