Read the current relationship
Use Read TFU Live master campaign families for the sub-account. This requirescampaigns:read and an agency administrator.
Inspect the returned relationship before changing it. A removed or rebound
campaign is reported as needing attention; it never silently joins another agent.
Set the relationship
Use Set TFU Live master campaign family withcampaigns:write and the intended campaigns. Each must belong to the
sub-account and share the same TFU Live profile. Read the saved relationship
back to verify it.
For general setup, see Build a TFU Live agent.
