# Processing

When it comes to the batch processing, there are two ways to use the Deepomatic API: Python script or Deepomatic CLI. 

### Python script

Run the python script below with the following arguments:

* endpoint: it corresponds to the deployment site and has the following URL: `https://api.{site-id}.customers.deepomatic.com`. For more information on how to retrieve, please refer to the [Authentication documentation](https://docs.deepomatic.com/platform-documentation/deepomatic-engage/integrating-visual-automation-applications/api-integration/authentication). 
* filename: it corresponds to the local path of the archive with the format specified [here](https://docs.deepomatic.com/platform-documentation/deepomatic-engage/integrating-visual-automation-applications/batch-processing/format).

{% code title="Script execution" %}

```bash
python3 upload.py endpoint filename
```

{% endcode %}

{% code title="upload.py" %}

```python
import sys

import requests


CHUNK_SIZE = 262144 * 2


def upload(endpoint: str, filepath: str):
    # Setup base headers with auth token
    headers = {
        'Authorization': f'Token {os.getenv("CUSTOMER_API_KEY")}',
        'content-type': 'application/json'
    }
    # Use endpoint to get a resumable url
    try:
        response = requests.post(
            f"{endpoint}/v0.2/batches",
            headers=headers
        )
        # check for bad answers
        response.raise_for_status()
        resumable_url = response.json()["upload_url"]
    except Exception as err:
        print(err)
        sys.exit(1)

    print(f"Using resumable_url: {resumable_url}")
    # Setup chunk tracking variables
    index = 0
    offset = 0
    content_size = os.stat(filepath).st_size

    # No more auth on the resumable_url.
    # Setting content-type
    headers = {
        'content-type': 'application/octet-stream'
    }
    with open(filepath, "rb") as archive:
        while True:
            chunk = archive.read(CHUNK_SIZE)
            if not chunk:
                break
            offset = index + len(chunk)
            headers['Content-Range'] = 'bytes %s-%s/%s' % (index, offset - 1, content_size)
            index = offset
            try:
                response = requests.put(resumable_url, data=chunk, headers=headers)
                print("response: %s, Content-Range: %s" % (response, headers['Content-Range']))
                print(response.text)
                response.raise_for_status()
            except Exception as err:
                print(err)


if __name__ == "__main__":
    if "--help" in sys.argv or len(sys.argv) != 3:
        print(
            "Usage:"
            "   upload.py <endpoint> <filepath>"
        )
    upload(sys.argv[1], sys.argv[2])
```

{% endcode %}

### Deepomatic CLI

Use the following command and specify:

* either the batch id if you have already created the batch via the GUI or the upload url if this is not the case
* the archive path

{% code title="Batch processing" %}

```bash
deepo site work_order batch upload -i batch_id -u upload_url -f archive_path
```

{% endcode %}
