How to Automatically Bypass AWS WAF CAPTCHA with CapSolver

#ai #aws #awschallenge #captcha

When working on large-scale scraping, monitoring, or automation projects, AWS WAF CAPTCHA is one of the toughest barriers you’ll face. It’s designed to keep bots out — but often blocks legitimate automated systems too.

In this guide, we’ll explore what AWS WAF CAPTCHA is, why it’s so challenging, and how to solve it automatically using CapSolver, both through a browser extension and a direct API integration.

What is AWS WAF CAPTCHA?

AWS WAF (Web Application Firewall) CAPTCHA helps websites prevent malicious activity by requiring suspicious users to complete a challenge before accessing content.

These challenges usually come in two main forms:

  1. Image recognition tasks — similar to reCAPTCHA, users must identify specific objects in a grid.
  2. Token-based validation — the browser must obtain a valid token (aws-waf-token) tied to the session.

Both are meant to verify humans — and both can block useful automated systems like scrapers or data collection bots.

Using CapSolver Browser Extension

If you prefer a no-code or low-code approach, the CapSolver browser extension is the simplest way to get started.
It automatically detects and solves AWS WAF CAPTCHAs in your browser, ideal for debugging or smaller automation workflows.

You can grab it here: CapSolver Extension

🧩 How to Set It Up

  1. Install the Extension
    Download it from Chrome Web Store, Firefox Add-ons, or GitHub.

  2. Add Your API Key
    Open the extension folder → locate config.js → insert your CapSolver API key.
    This authenticates the extension with your account.

  3. Enable AWS WAF CAPTCHA Solving
    In config.js, ensure this flag is enabled:

   enabledForAwsCaptcha: true
Enter fullscreen mode Exit fullscreen mode

  1. Detect Parameters Automatically Open Developer Tools → find the “Capsolver Captcha Detector” tab. When a CAPTCHA appears, you’ll see the extracted parameters like awsKey, awsIv, and awsContext.

Integrating CapSolver with Puppeteer or Selenium

CapSolver also works directly with your automation scripts.
Here’s how to load the extension in Puppeteer (Node.js):

const puppeteer = require("puppeteer");

(async () => {
  const pathToExtension = "/path/to/capsolver_extension";
  const browser = await puppeteer.launch({
    headless: false,
    args: [
      `--disable-extensions-except=${pathToExtension}`,
      `--load-extension=${pathToExtension}`
    ],
  });
  const page = await browser.newPage();
  await page.goto("https://your-target-website.com");
})();
Enter fullscreen mode Exit fullscreen mode

Or in Selenium (Python):

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_extension("./capsolver_extension.zip")
driver = webdriver.Chrome(options=options)
driver.get("https://your-target-website.com")
Enter fullscreen mode Exit fullscreen mode

Both setups will automatically trigger the extension to solve AWS WAF CAPTCHAs when they appear.

Solving AWS WAF CAPTCHA via API

For large-scale or backend automation, CapSolver’s API integration is more flexible and scalable.
It supports both image-based and token-based AWS CAPTCHA tasks.

1. Image-Based CAPTCHA (AwsWafClassification)

Send a request like this:

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "AwsWafClassification",
    "websiteURL": "https://your-target-website.com",
    "images": ["/9j/4AAQSkZJRgAB..."],
    "question": "aws:grid:chair"
  }
}
Enter fullscreen mode Exit fullscreen mode

The response includes the correct image positions or IDs to click.

2. Token-Based CAPTCHA (AntiAwsWafTask / ProxyLess) 

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "AntiAwsWafTaskProxyLess",
    "websiteURL": "https://your-target-website.com",
    "awsKey": "...",
    "awsIv": "...",
    "awsContext": "..."
  }
}
Enter fullscreen mode Exit fullscreen mode

You’ll get a task ID; poll getTaskResult until you receive the solved token (aws-waf-token) in the cookie field.
