​
Feature Overview

For complex documents containing multiple files of multiple categories, the file splitting function supports intelligent recognition of document content to achieve automatic splitting and classification of documents.

​
Use Cases

​
1. Medical Insurance Claims Scenario

A multi-page file contains:
  • Pages 1-2: Insurance policy information
  • Pages 3-5: Medical invoices
  • Pages 6-10: Hospitalization records
Through the file splitting function, these three different types of documents can be split separately, facilitating subsequent classification and extraction processing.

​
2. Logistics Import/Export Scenario

One file contains:
  • Page 1: Export customs declaration
  • Page 2: Commercial invoice
  • Page 3: Packing List
  • Page 4: Sales contract
The file splitting function can intelligently split by document type.

​
API Parameter Configuration

​
Enable File Splitting Function

Set split_flag=true in the upload interface to enable the file splitting function: 
curl -X POST \
  -H "x-ti-app-id: <your-app-id>" \
  -H "x-ti-secret-code: <your-secret-code>" \
  -F "file=@/path/to/multi-page-document.pdf" \
  "https://docflow.textin.com/api/app-api/sip/platform/v2/file/upload?workspace_id=<your-workspace-id>&split_flag=true"

Return Result Description

​
File Splitting Result Structure

After enabling the file splitting function, the result returned by the file/fetch interface will include the child_files field, which describes the information of sub-documents after splitting: 
{
  "code": 200,
  "result": {
    "files": [
      {
        "id": "parent-file-001",
        "name": "multi-document.pdf",
        "format": "pdf",
        "child_files": [
          {
            "id": "child-001",
            "task_id": "task-001",
            "task_type": 0,  // 0 indicates sub-file generated by file splitting
            "name": "multi-document.pdf#1",
            "format": "pdf",
            "category": "invoice",
          },
          {
            "id": "child-002", 
            "task_id": "task-002",
            "task_type": 0,
            "name": "multi-document.pdf#2",
            "format": "pdf",
            "category": "contract",
