👨‍💻 Node.JS Code for solve DataDome with proxy

Here's a Node.JS sample script to accomplish the task:

const axios = require('axios');


const CLIENT_KEY = "your capsolver.com api key";  // Replace with your CAPSOLVER API Key

const headers = {

    });
    return res.data;
  } catch (error) {

  }
}

    }

  const taskData = await createTask(taskPayload);
  return await getTaskResult(taskData.taskId);
}

function sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
}
async function main() {
  try {

    //Obtain these values for create the geoCaptcha URL. Sometimes datadome provide the url directly and other times the values. 
    //In this case, they return the values, so we need to make the geo captcha url
    let initialCid = "initial cid value"
    let cid = "value cid "

    let proxy = "your proxy"
    let geoCaptchaURL = `https://geo.captcha-delivery.com/captcha/?initialCid=${initialCid}&cid=${cid}&referer=${encodeURIComponent(referer)}&hash=${hash}&t=${t}&s=${s}&e=${e}`;
    // Be sure to obtain always a different geo captcha url, can't be the same 
    let solution = await solveDatadome(geoCaptchaURL,userAgent, proxy )
    console.log(solution)
    }
catch (error) {
    console.error(`Error: ${error}`);
  }
}

main();

⚠️ Change these variables

• PROXY: Change to your proxy
