Reactivate campaign

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.

Response

{
  "campaignId": "cmp_987654321",
  "campaignName": "Q2 2026 Tech Launch",
  "previousStatus": "PAUSED",
  "newStatus": "ACTIVE",
  "totalMediaBuys": 2,
  "successCount": 2,
  "failureCount": 0,
  "mediaBuyResults": [
    { "mediaBuyId": "mb_abc123", "name": "Q2 2026 Tech Launch - Example Media", "previousStatus": "PAUSED", "success": true },
    { "mediaBuyId": "mb_def456", "name": "Q2 2026 Tech Launch - Display", "previousStatus": "PAUSED", "success": true }
  ]
}

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.
