ເງື່ອນໄຂເບື້ອງຕົ້ນ: ຮັກສາ API Key ຂອງທ່ານໃຫ້ປອດໄພ

Before making any API calls, you need to obtain an API key from your Doctranslate developer dashboard. This key is your unique identifier and must be included in the headers of every request for authentication purposes.
ປະຕິບັດຕໍ່ key ນີ້ຄືກັບ sensitive credential; it should be stored securely, for instance, as an environment variable, and never exposed in client-side code.
Without a valid API key, all your requests to the translation endpoints will be rejected with an authentication error.

ຂັ້ນຕອນທີ 1: ການຕັ້ງຄ່າສະພາບແວດລ້ອມ Python ຂອງທ່ານ

To begin, ensure you have Python installed on your system. We will be using the popular `requests` library to handle HTTP communication with the Doctranslate API.
If you do not have it installed, you can easily add it to your environment using pip, Python’s package installer.
Simply run the command `pip install requests` in your terminal, and you’ll be ready to start writing the integration code for your project.

ຂັ້ນຕອນທີ 2: ການສ້າງຄໍາຮ້ອງຂໍການແປ

The core of the integration is submitting the PDF file for translation. This is done by sending a `POST` request to the `/v2/translate` endpoint.
The request must be a `multipart/form-data` request, as it contains both the binary file data and the translation parameters.
Key parameters include `source_lang` (‘en’), `target_lang` (‘zh-CN’ for Simplified Chinese), and of course, the file itself. For a seamless experience that ຮັກສາຮູບແບບແລະຕາຕະລາງຂອງທ່ານໃຫ້ສົມບູນແບບ, our API is specifically designed to handle complex formatting with ease.

Below is a Python code example demonstrating how to construct and send this request. It opens the PDF file in binary mode, sets up the necessary headers with your API key, and defines the data payload for the API call.
The response from this initial request will not contain the translated file directly but rather a `document_id` that you will use to track the translation’s progress.
This asynchronous approach is essential for handling translations that may take some time, ensuring your application remains responsive.

import requests
import time
import os

# Your API key from the Doctranslate developer dashboard
API_KEY = os.getenv("DOCTRANSLATE_API_KEY", "your_api_key_here")

# API endpoints
TRANSLATE_URL = "https://developer.doctranslate.io/v2/translate"
STATUS_URL = "https://developer.doctranslate.io/v2/status"

# Path to the source document
file_path = "path/to/your/document.pdf"

def submit_translation_request(file_path):
    """Submits the PDF for translation."""
    headers = {
        "Authorization": f"Bearer {API_KEY}"
    }
    
    files = {
        "file": (os.path.basename(file_path), open(file_path, "rb"), "application/pdf")
    }
    
    data = {
        "source_lang": "en",
        "target_lang": "zh-CN", # Use 'zh-TW' for Traditional Chinese
        "tone": "Serious" # Optional: specify the tone
    }
    
    print("Submitting document for translation...")
    response = requests.post(TRANSLATE_URL, headers=headers, files=files, data=data)
    
    if response.status_code == 200:
        document_id = response.json().get("document_id")
        print(f"Successfully submitted. Document ID: {document_id}")
        return document_id
    else:
        print(f"Error submitting document: {response.status_code} - {response.text}")
        return None

# Example usage:
document_id = submit_translation_request(file_path)

ຂັ້ນຕອນທີ 3: ການສອບຖາມຫາສະຖານະສຳເລັດ
After you have successfully submitted your document and received a `document_id`, you must periodically check the translation status. This is done by making `GET` requests to the `/v2/status` endpoint, including the `document_id` as a query parameter.
The API will respond with the current status of the job, which can be ‘processing’, ‘completed’, or ‘failed’.
It is best practice to implement a polling mechanism with a reasonable delay, such as every 5-10 seconds, to avoid overwhelming the API with requests.
Once the status returned in the JSON response changes to ‘completed’, the translated document is ready for download. The response for a completed job will also contain a `download_url` field.
This URL is a temporary, secure link that you can use to retrieve the final translated PDF file.
If the status is ‘failed’, the response will include an error message to help you diagnose the issue with the translation job.
def check_translation_status(document_id):
    """Polls the API to check the status of the translation."""
    headers = {
        "Authorization": f"Bearer {API_KEY}"
    }
    params = {
        "document_id": document_id
    }
    
    while True:
        print("Checking translation status...")
        response = requests.get(STATUS_URL, headers=headers, params=params)
        
        if response.status_code == 200:
            data = response.json()
            status = data.get("status")
            
            if status == "completed":
                print("Translation completed!")
                download_url = data.get("download_url")
                return download_url
            elif status == "failed":
                print(f"Translation failed: {data.get('error')}")
                return None
            else:
                # Wait before polling again
                print("Translation is still in progress...")
                time.sleep(10)
        else:
            print(f"Error checking status: {response.status_code} - {response.text}")
            return None

# Example usage:
if document_id:
    download_url = check_translation_status(document_id)

ຂັ້ນຕອນທີ 4: ການດາວໂຫລດ PDF ທີ່ແປແລ້ວຂອງທ່ານ
The final step is to download the translated file using the `download_url` obtained from the status check. This involves making a simple `GET` request to the provided URL.
The response will contain the binary data of the translated PDF file, which you can then save to your local filesystem.
Remember that this URL is typically time-sensitive for security reasons, so you should use it promptly once it becomes available to you.
def download_translated_file(download_url, output_path):
    """Downloads the translated file from the provided URL."""
    print(f"Downloading translated file from {download_url}")
    response = requests.get(download_url)
    
    if response.status_code == 200:
        with open(output_path, "wb") as f:
            f.write(response.content)
        print(f"File successfully saved to {output_path}")
    else:
        print(f"Error downloading file: {response.status_code} - {response.text}")

# Example usage:
if download_url:
    output_file_path = "path/to/your/translated_document_zh.pdf"
    download_translated_file(download_url, output_file_path)

Languages vary in density, and Chinese is known for its conciseness. A sentence translated from English to Chinese will often occupy less physical space, a phenomenon known as text contraction.
