Errors

• 400 — if the content (subject/body) is missing or there are no recipients.
• 402 — if the wallet balance is too low (nothing is sent and the campaign is left as it was).
• 409 — unless the campaign is draft or scheduled, or if it changed state while starting.
• 502 — with campaign_id if the send failed; the campaign is marked failed.
• 404 — if the campaign is not in this sub-account.

Notes

Returns 200 with the updated campaign and a send summary (summary may be null) when the send finishes quickly. A large send that is still going after about 8 seconds returns 202 with { campaign_id, campaign_status: “running”, recipients, accepted: true } and continues in the background — poll Get a campaign or Get campaign stats.
