# Run a manual-audience automation

`POST /v1/automations/{automationId}/run`

Launches a MANUAL-AUDIENCE automation against the audience bound to its trigger node. `dry_run: true` previews without sending; `scheduledAt` launches later. Percentage-based `gradualSend` delivers each send step in custom hour or calendar-day batches and supports manual pause/resume/cancel. `400` when the resolved plan exceeds 50,000 recipients, 30 batches, or 30 elapsed days. Returns `202` with the `audienceRunId`.

## Other responses

- `202` — Run launched (or scheduled).
- `401` — The API key was missing, invalid, or revoked.
- `403` — The caller does not have the required `automations` permission.
- `404` — Automation not found in the API-key brand. Cross-brand ids intentionally surface as 404 (never 403) so the API does not leak cross-brand existence.
- `409` — The same `Idempotency-Key` was reused with a different request body.
- `429` — The request hit the rolling rate limit window.
- `500` — Unexpected internal error.
