Here is a simple integration script.

import requests

api_url = "https://api.doctranslate.io/v3/translate"
headers = {"Authorization": "Bearer YOUR_API_KEY"}
data = {

response = requests.post(api_url, headers=headers, json=data)
print(response.json())
JavaScript is perfect for web apps. 
 Use the fetch API for requests. 
 Handle the response with modern promises.
const translateDoc = async () => {
  const response = await fetch('https://api.doctranslate.io/v3/translate', {
    method: 'POST',
    headers: { 'Authorization': 'Bearer YOUR_KEY' },
    body: JSON.stringify({ source: 'en', target: 'es' })
  });
  const result = await response.json();
  console.log(result);
};
