POST /api/v2/buyer/campaigns/:id/reactivate Brings a PAUSED campaign back to ACTIVE. This is the only way to resume a paused campaign. Media buys return to ACTIVE (post-flight if their dates allow).
reactivate and execute are distinct endpoints. execute launches a DRAFT or COMPLETED campaign for the first time (or relaunches it). reactivate resumes a PAUSED campaign.

  • Reactivation brings every media buy back to ACTIVE (post-flight if dates allow).
  • previousStatus / newStatus — campaign status before and after the call.
  • successCount / failureCount — how many media buy cascade operations succeeded or failed. Partial failures are possible; the campaign is still marked ACTIVE even when failureCount > 0.
