How to Integrate a French Document Translation API (Step-by-Step)

Create Pre-signed Upload URL

Before uploading your French document, you must request a secure, temporary URL. This ensures that your data is handled with enterprise-grade security. For scanned documents, remember to set the OCR parameter.

Success: You receive a file_id and a unique upload_url.

Submit the Translation Task

Once the file is uploaded, trigger the translation engine. This is where you specify that the source is French. Integrating the best AI translation API alternative to DeepL allows for superior context handling.

Common Mistake: Using the wrong ISO code. Always use "fr" for French.

Python Implementation Example

Automate the entire workflow using this Python script. It handles the submission and polling logic required for the fastest file translation API performance.

import requests
import time

# Submit translation for a French document
response = requests.post(
    f"{BASE_URL}/translate/document",
    json={
        "file_id": int(file_id),
        "source_language": "fr",
        "target_language": "en",
        "trans_mode": "master"
    },
    headers=headers
)

# Poll status until completed
while True:
    status_resp = requests.post(
        f"{BASE_URL}/translate/status",
        json={"file_id": file_id},
        headers=headers
    )
    result = status_resp.json()["data"]
    if result["status_name"] == "completed":
        print(f"Download URL: {result['download_url']}")
        break
    time.sleep(5)
