How to get websiteKey (captchaAppId)

Turn on the Developer Tools, go to the Network tab, activate the captcha and look at the requests. Some of them will contain the parameter value you need. In this case websiteKey=aid

How to get captchaUrl

Open Developer Tools, go to the Network tab, trigger the captcha, and inspect the network requests. Among them, you will find TCaptcha.js or TCaptcha-global.js, where you can find a link like this:

How to Find All Required Parameters for Task Creation

Automatically

A convenient way to automate the search for all necessary parameters. Some parameters are regenerated every time the page loads, so you'll need to extract them through a browser — either regular or headless (e.g., using Playwright). Since the values of dynamic parameters are short-lived, the captcha must be solved immediately after retrieving them.

Important!

The code snippets provided are basic examples for familiarization with extracting the required parameters. The exact implementation will depend on your captcha page, its structure, and the HTML elements/selectors it uses.

JavaScript

Show code (Node.js)

import { chromium } from "playwright";

(async () => {
  const browser = await chromium.launch({ headless: false });
  const page = await browser.newPage();

  // Intercept requests
  page.on("request", (request) => {
    const url = request.url();
    if (
      url.startsWith("https://sg.captcha.qcloud.com/cap_union_prehandle?aid=")
    ) {
      const parsedUrl = new URL(url);
      const aid = parsedUrl.searchParams.get("aid");
      console.log("Extracted aid:", aid);
    }
  });

  await page.goto("https://www.example.com/", { waitUntil: "load" });

  await page.waitForTimeout(5000);

  await browser.close();
})();

Python

Show code

import asyncio
from playwright.async_api import async_playwright

async def main():
    async with async_playwright() as p:
        browser = await p.chromium.launch(headless=False)
        page = await browser.new_page()

        # Intercept requests
        page.on("request", lambda request: handle_request(request))

        await page.goto("https://www.example.com/", wait_until="load")

        await asyncio.sleep(5)

        await browser.close()

def handle_request(request):
    url = request.url
    if url.startswith("https://sg.captcha.qcloud.com/cap_union_prehandle?aid="):
        parsed_url = request.url.split('?')[1]
        params = dict(param.split('=') for param in parsed_url.split('&') if '=' in param)
        aid = params.get('aid')
        print("Extracted aid:", aid)

asyncio.run(main())

C#

Show code

using System;
using System.Threading.Tasks;
using Microsoft.Playwright;

class Program
{
    public static async Task Main()
    {
        using var playwright = await Playwright.CreateAsync();
        await using var browser = await playwright.Chromium.LaunchAsync(new BrowserTypeLaunchOptions {
           Headless = false });
        var page = await browser.NewPageAsync();

        // Intercept requests
        page.Request += (_, request) =>
        {
            var url = request.Url;
            if (url.StartsWith("https://sg.captcha.qcloud.com/cap_union_prehandle?aid="))
            {
                var uri = new Uri(url);
                var queryParams = System.Web.HttpUtility.ParseQueryString(uri.Query);
                var aid = queryParams.Get("aid");
                Console.WriteLine("Extracted aid: " + aid);
            }
        };

        await page.GotoAsync("https://www.example.com/", new PageGotoOptions {
         WaitUntil = WaitUntilState.Load });

        await Task.Delay(5000);

        await browser.CloseAsync();
