# Bulk create sequence steps

`POST /v3/sequences/{id}/steps/bulk`

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

Creates multiple steps in a sequence at once. Returns a list of results for each step. Email-step variants may carry up to **3** `attachmentIds` each; inaccessible attachment IDs surface as a per-item `forbidden` result (upload first via `POST /v3/attachments`).

## Path parameters

- `id` integer, required

## Request body

- union[]
  - union
    - object — Email step with variant configuration
      - `id` integer, nullable — Unique identifier for the step
      - `parentId` integer, nullable — ID of the parent step (for branching)
      - `ifConditionPositive` boolean, nullable — Whether this step is on the positive branch of a condition
      - `type` 'email', required — Step type discriminator
      - `delayInMinutes` integer, required — Delay in minutes before executing this step

## Response `200`

Array of per-item results, one per input step (same order as request).

Possible per-item error codes:

| Error code | Meaning |
|-------|---------|
| `invalidInput` | Validation failed (e.g. more than 3 attachments on a variant) |
| `invalidStep` | Step type or configuration is invalid |
| `forbidden` | One or more attachment IDs are not accessible to the caller |
| `internalError` | Unexpected server error |
| `stepLocked` | Step cannot be modified |

- object[]
  - `id` integer, nullable — ID of the created resource, null if creation failed
  - `error` integer, nullable — Error code if creation failed
  - `errorDetails` string, nullable — Human-readable error description if creation failed

## Other responses

- `400` — Invalid sequence id, or a business-rule rejection.
- `401` — Unauthorized. The response body is empty; check the `WWW-Authenticate` header for the expected scheme.
- `403` — Caller does not have permission to modify this sequence. Per-item attachment-accessibility failures surface as `forbidden` entries in the 200 result array, not as a top-level 403.
- `409` — A step in the sequence is locked and blocks bulk creation
- `429` — Too Many Requests
