# Classification Only

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

<CodeGroup>
  ```bash curl icon=terminal wrap theme={null}
  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"
  ```

  ```python Python expandable icon=python lines theme={null}
  import requests
  from requests_toolbelt.multipart.encoder import MultipartEncoder
  import os

  ti_app_id = "<your-app-id>"
  ti_secret_code = "<your-secret-code>"
  workspace_id = "<your-workspace-id>"
  filepath = "/path/to/your/file.pdf"

  host = "https://docflow.textin.ai"
  url = "/api/app-api/sip/platform/v2/file/upload"

  mime_type = "application/pdf"
  if filepath.lower().endswith((".jpg", ".jpeg", ".png")):
      mime_type = "image/jpeg"

  payload = MultipartEncoder(fields={
      "file": (os.path.basename(filepath), open(filepath, "rb"), mime_type)
  })

  resp = requests.post(
      url=f"{host}{url}",
      params={
          "workspace_id": workspace_id,
          "target_process": "classify"
      },
      data=payload.to_string(),
      headers={
          "Content-Type": payload.content_type,
          "x-ti-app-id": ti_app_id,
          "x-ti-secret-code": ti_secret_code,
      },
      timeout=60,
  )

  print(resp.status_code, resp.text)
  ```
</CodeGroup>

## Query Classification Results

Use the `file/fetch` interface to query classification results:

<CodeGroup>
  ```bash curl icon=terminal wrap theme={null}
  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>"
  ```

  ```python Python expandable icon=python lines theme={null}
  import requests

  resp = requests.get(
      "https://docflow.textin.ai/api/app-api/sip/platform/v2/file/fetch",
      params={
          "workspace_id": "<your-workspace-id>",
          "file_id": "<your-file-id>",
      },
      headers={"x-ti-app-id": "<your-app-id>", "x-ti-secret-code": "<your-secret-code>"},
      timeout=60,
  )

  data = resp.json()
  for f in data.get("result", {}).get("files", []):
      print(f"File ID: {f['id']}")
      print(f"File name: {f.get('name')}")
      print(f"Classification result: {f.get('category')}")
      print(f"Recognition status: {f.get('recognition_status')}")
  ```
</CodeGroup>

## 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)

### Return Example

```json expandable theme={null}
{
  "code": 200,
  "result": {
    "files": [
      {
        "id": "202412190001",
        "name": "invoice.pdf",
        "category": "invoice",
        "recognition_status": 10,
        "data": null
      }
    ]
  }
}
```
