      Job to create for each file in the source directory.

      - `ConfigurationID string`

        Saved product configuration ID matching the job type.

      - `Type BatchNewParamsConfigJobType`

        Product job type to run for each source directory file.

        - `const BatchNewParamsConfigJobTypeParseV2 BatchNewParamsConfigJobType = "parse_v2"`

        - `const BatchNewParamsConfigJobTypeExtractV2 BatchNewParamsConfigJobType = "extract_v2"`

  - `SourceDirectoryID param.Field[string]`

    Body param: Directory whose files should be processed.

  - `OrganizationID param.Field[string]`

    Query param

  - `ProjectID param.Field[string]`

    Query param

### Returns

- `type BatchNewResponse struct{…}`

  A top-level batch.

  Example:
  {
  "id": "bat-aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
  "project_id": "prj-aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
  "source_directory_id": "dir-aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
  "config": {
  "job": {
  "type": "parse_v2",
  "configuration_id": "cfg-aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"
  }
  },
  "status": "COMPLETED",
  "results": [
  {
  "source_directory_file_id": "dfl-aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
  "job_reference": {
  "type": "parse_v2",
  "id": "pjb-aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"
  },
  "error_message": null
  }
  ]
  }

  Batch-level `FAILED` means the orchestration failed and cannot provide a
  reliable per-file result set. `results` is only populated when explicitly
  requested with `expand=results` and may be `null` while a batch is still
  running or before result mappings are available.

  - `ID string`

    Unique identifier

  - `Config BatchNewResponseConfig`

    Batch configuration snapshot.

    - `Job BatchNewResponseConfigJob`

      Job to create for each file in the source directory.

      - `ConfigurationID string`

        Saved product configuration ID matching the job type.

      - `Type BatchNewResponseConfigJobType`

        Product job type to run for each source directory file.

        - `const BatchNewResponseConfigJobTypeParseV2 BatchNewResponseConfigJobType = "parse_v2"`

        - `const BatchNewResponseConfigJobTypeExtractV2 BatchNewResponseConfigJobType = "extract_v2"`

  - `ProjectID string`

    Project this batch belongs to.

  - `SourceDirectoryID string`

    Directory being processed.

  - `Status BatchNewResponseStatus`

    Current batch status.

    - `const BatchNewResponseStatusPending BatchNewResponseStatus = "PENDING"`

    - `const BatchNewResponseStatusThrottled BatchNewResponseStatus = "THROTTLED"`

    - `const BatchNewResponseStatusRunning BatchNewResponseStatus = "RUNNING"`

    - `const BatchNewResponseStatusCompleted BatchNewResponseStatus = "COMPLETED"`

    - `const BatchNewResponseStatusFailed BatchNewResponseStatus = "FAILED"`

    - `const BatchNewResponseStatusCancelled BatchNewResponseStatus = "CANCELLED"`

  - `CreatedAt Time`

    Creation datetime

  - `Results []BatchNewResponseResult`

    Expanded per-file result mappings. Null unless requested with expand=results, or until result mappings are available.

    - `SourceDirectoryFileID string`

      Source directory file processed by this batch.

    - `ErrorMessage string`

      Batch-level mapping error if the system could not create or associate a job for this source file.

    - `JobReference BatchNewResponseResultJobReference`

      Reference to a job produced by a batch.

      Example:
      {
      "type": "parse_v2",
      "id": "pjb-aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"
      }

      - `ID string`

        Job ID, such as a parse job ID.

      - `Type BatchNewResponseResultJobReferenceType`

        Type of job produced for the file.

        - `const BatchNewResponseResultJobReferenceTypeParseV2 BatchNewResponseResultJobReferenceType = "parse_v2"`

        - `const BatchNewResponseResultJobReferenceTypeExtractV2 BatchNewResponseResultJobReferenceType = "extract_v2"`

  - `UpdatedAt Time`

    Update datetime
