# Resume Segment Endpoint

`POST /api/agent-chat/segments/{segment_id}/resume`

Resume a paused Campaign through the shared start orchestration.

Only legal from `listening`. If targeting changed while paused, this moves
the Campaign back to discovery and enqueues Retarget before any old
outreach can resume; otherwise it resumes the prior lifecycle normally.

Refuses with 402 when the org can't afford even one more email — same
`Email Affordability Gate` the sender-worker `_precheck` and
POST `/api/app-auto-gtm/segments/{id}/launch` already share. Without
this check, resuming a debt-paused or empty-wallet campaign would
immediately stall again on the per-send precheck.
