## Create Split Job

`split.create(SplitCreateParams**kwargs)  -> SplitCreateResponse`

**post** `/api/v1/split/jobs`

Create a document split job.

### Parameters

- `file_input: str`

  File ID or parse job ID

- `organization_id: Optional[str]`

- `project_id: Optional[str]`

- `configuration: Optional[Configuration]`

  Split configuration with categories and splitting strategy.

  - `categories: Iterable[SplitCategoryParam]`

    Categories to split documents into.

    - `name: str`

      Name of the category.

    - `description: Optional[str]`

      Optional description of what content belongs in this category.

  - `splitting_strategy: Optional[ConfigurationSplittingStrategy]`

    Strategy for splitting documents.

    - `allow_uncategorized: Optional[Literal["forbid", "include", "omit"]]`

      Controls handling of pages that don't match any category. 'include': pages can be grouped as 'uncategorized' and included in results. 'forbid': all pages must be assigned to a defined category. 'omit': pages can be classified as 'uncategorized' but are excluded from results.

      - `"forbid"`

      - `"include"`

      - `"omit"`

    - `custom_instructions: Optional[str]`

      Free-form guidance for where segment boundaries are placed.

    - `min_pages_per_split: Optional[int]`

      Minimum pages per segment. Shorter segments are merged into an adjacent segment; 1 disables merging.

- `configuration_id: Optional[str]`

  Saved configuration ID

- `transaction_id: Optional[str]`

  Idempotency key scoped to the project. Reusing a key returns the original job; the new request body is ignored.

  IDs of saved webhook configurations to notify for this job.

- `webhook_configurations: Optional[Iterable[WebhookConfiguration]]`

  Outbound webhook endpoints to notify on job status changes

  - `webhook_events: Optional[List[Literal["batch.cancelled", "batch.error", "batch.pending", 30 more]]]`

    Events to subscribe to (e.g. 'parse.success', 'extract.error'). If null, all events are delivered.

    - `"batch.cancelled"`

    - `"batch.error"`

    - `"batch.pending"`

    - `"batch.running"`

    - `"batch.success"`

    - `"classify.cancelled"`

    - `"classify.error"`

    - `"extract.error"`

    - `"extract.partial_success"`

    - `"extract.pending"`

    - `"extract.success"`

    - `"parse.cancelled"`

    - `"parse.error"`

    - `"parse.partial_success"`

    - `"parse.running"`

    - `"parse.success"`

    - `"sheets.cancelled"`

    - `"sheets.error"`

    - `"sheets.partial_success"`

    - `"sheets.pending"`

    - `"sheets.success"`

    - `"split.cancelled"`

    - `"split.error"`

    - `"split.pending"`

    - `"split.processing"`

    - `"split.success"`

    - `"unmapped_event"`

  - `webhook_headers: Optional[Dict[str, str]]`

    Custom HTTP headers sent with each webhook request (e.g. auth tokens)

  - `webhook_output_format: Optional[str]`

    Response format sent to the webhook: 'string' (default) or 'json'

  - `webhook_signing_secret: Optional[str]`

    Shared signing secret used to sign webhook deliveries. When set, each request includes an HMAC-SHA256 signature of the request body in the 'LC-Signature' header (value 'sha256=<hex>'). Recompute the HMAC over the raw request body with this secret to verify the delivery is authentic.

  - `webhook_url: Optional[str]`

    URL to receive webhook POST notifications
