# Bulk start sequences

`POST /v3/sequences/start`

<small>_Requires the `sequences:operate` scope (or a broader one that includes it)._</small>

Starts multiple sequences at once. Non-atomic — some may succeed while others fail.

## Request body

- object
  - `ids` integer[], required — List of sequence IDs to start

## Response `200`

Dictionary of failed items keyed by sequence ID. Empty object `{}` means all succeeded.

Per-item failures use the `SequenceActionError` enum. Common per-item slugs:

| Slug | Meaning |
| --- | --- |
| `notFound` | Sequence does not exist |
| `forbidden` | Caller lacks permission for this sequence |
| `archived` | Sequence is archived |
| `noContacts` | Sequence has no contacts |
| `noEmailAccounts` | Sequence has no email accounts |
| `salesAgentNotAllowed` | Operation not permitted on a sales-agent sequence |

- object

## Other responses

- `400` — Validation failure on the request body, or a business rule rejection.
- `401` — Unauthorized. The response body is empty; check the `WWW-Authenticate` header for the expected scheme.
- `403` — User lacks required feature scope to start sequences
- `429` — Too Many Requests
