latestOpenAPI 3.1.02026-07-267154122.0 KBResume a campaign (idempotent; ?dryRun=true)
Resumes the campaign from where its sequences left off (the same active transition as launch; resume vs fresh-launch facts are derived from prior state). Idempotent. ?dryRun=true returns { dryRun: true, campaignId, wouldResume } with no writes; a real resume returns the transition result carrying the resume facts.
Query parameters
Headers
Transport-level replay protection — any v2 POST may send it (1–255 printable ASCII characters; UUIDs recommended). The first response for a key is recorded and replayed verbatim for retries with the same key + method/path/body for 24 hours; replayed responses carry the Idempotency-Replay: true response header. Reusing a key with a different request — or retrying while the original is still in flight — returns 409 IDEMPOTENCY_ERROR. 5xx responses are never recorded (the retry re-executes).
Response
The transition result — or the dryRun report.
