Docflow performs the complete parsing->classification->extraction workflow by default.
If business requirements only need classification results, you can add the target_process=classify parameter to the upload interface, and the workflow will terminate after completing classification, skipping the extraction process.

​
Upload Files for Classification Only

curl -X POST \
  -H "x-ti-app-id: <your-app-id>" \
  -H "x-ti-secret-code: <your-secret-code>" \
  -F "file=@/path/to/your/file.pdf" \
  "https://docflow.textin.ai/api/app-api/sip/platform/v2/file/upload?workspace_id=<your-workspace-id>&target_process=classify"

​
Query Classification Results

Use the file/fetch interface to query classification results: 
curl \
  -H "x-ti-app-id: <your-app-id>" \
  -H "x-ti-secret-code: <your-secret-code>" \
  "https://docflow.textin.ai/api/app-api/sip/platform/v2/file/fetch?workspace_id=<your-workspace-id>&file_id=<your-file-id>"

​
Recognition_status Status Description for Classification Only

When using target_process=classify for classification only, the recognition_status field will have the following status changes:

​
Status Value Description

  • 0 - Pending recognition: File just uploaded, waiting for processing
  • 3 - Classifying: Classification processing in progress
  • 10 - Classification complete: Final state for classification-only workflow, indicating classification is complete and extraction will not be performed
  • 2 - Classification failed: Error occurred during classification process

​
Difference from Complete Workflow

Complete workflow (default) status changes:
  • 0 → 3 → 4 → 1 (Pending recognition → Classifying → Extracting → Recognition successful)
Classification-only workflow status changes:
  • 0 → 3 → 10 (Pending recognition → Classifying → Classification complete)
