Attach Audience To Campaign

PUT
/campaigns/{campaign_id}/audience

Attach (or detach) a saved list to a campaign as its audience.

This is the missing link in Daniel’s MCP flow: find list → create campaign → attach audience → launch was previously a dead-end because no REST/MCP path could set cb_campaigns.audience_list_id (the FE “Attach Audience” dialog only went through an internal route).

Idempotent — setting the same list twice is a 200, no error. Pass list_id=null to detach. The launch endpoint reads cb_campaigns.audience_list_id when enrolling contacts; without it, launch creates a sequence with zero enrollment.
