How to Solve AWS e in n8n with CapSolver

AWS WAF (Web Application Firewall) is Amazon's enterprise-grade bot protection system used by some of the largest websites on the internet. Unlike traditional CAPTCHAs that show image puzzles or checkboxes, AWS WAF uses invisible challenges and token-based verification โ€” making it particularly challenging for automation tools to handle.

What if you could solve AWS WAF challenges automatically inside your n8n workflows โ€” whether you're building a reusable solver API, scraping a captcha-protected site, or automating a login form โ€” all without writing a single line of traditional code?

In this guide, you'll learn how to combine n8n (a visual workflow automation tool) with CapSolver (an AI-powered captcha solving service) to solve AWS WAF challenges on demand โ€” either as a standalone API endpoint or as a step inside any automation workflow.

What you'll build:

Solver API โ€” a reusable endpoint your other tools can call:

  • An AWS WAF solver API

Direct-use workflows โ€” CapSolver embedded as a step inside larger automations:

  • A price & product scraper that solves AWS WAF, fetches protected pages, and alerts on price changes
  • An account login automation that solves AWS WAF before submitting credentials

What is AWS WAF?

AWS WAF (Web Application Firewall) is Amazon Web Services' bot mitigation and web security service. It protects websites from common web exploits, bot traffic, and automated abuse. Many high-traffic sites โ€” especially e-commerce platforms, financial services, and enterprise applications โ€” use AWS WAF to gate access behind invisible CAPTCHA challenges.

How AWS WAF differs from reCAPTCHA and Turnstile:

  • Cookie-based authentication โ€” Instead of returning a token you submit in a form field, AWS WAF returns an aws-waf-token cookie that must be sent with subsequent requests via the Cookie HTTP header.
  • Multiple optional parameters โ€” AWS WAF may expose awsKey, awsIv, awsContext, awsChallengeJS, and other parameters depending on the site's configuration. These are optional and only needed for specific implementations.
  • Invisible challenge โ€” AWS WAF challenges typically run entirely in the background using JavaScript, with no visible widget for the user to interact with.

Not the same as CloudFront. AWS WAF is the firewall layer that sits in front of web applications. CloudFront is Amazon's CDN. A site can use CloudFront without AWS WAF, or AWS WAF without CloudFront โ€” they are separate services, though commonly used together.

Prerequisites

Before getting started, make sure you have the following:

  1. An n8n instance โ€” Either self-hosted or n8n Cloud
  2. A CapSolver account โ€” Sign up here and get your API key
  3. The CapSolver n8n node โ€” Already available as an official node in n8n (no installation needed)

Important: Make sure you have sufficient balance in your CapSolver account. AWS WAF solving tasks consume credits based on usage.

Setting Up CapSolver in n8n

CapSolver is available as an official integration in n8n โ€” no community node installation required. You can find it directly in the node panel when building your workflows.

Since it's an official integration, you need to create a credential in n8n so that the CapSolver node can authenticate with your account.

Step 1: Open the Credentials Page

Go to your n8n instance and navigate to Settings -> Credentials. You'll see all your configured credentials here.

Step 2: Create the CapSolver Credential

  1. Click Create credential (top right)
  2. Search for "CapSolver" and select CapSolver API
  3. Enter your API Key โ€” copy it directly from the CapSolver Dashboard
  4. Leave Allowed HTTP Request Domains set to All (default)
  5. Click Save

n8n will automatically test the connection. You should see a green "Connection tested successfully" banner confirming your API key is valid.

CapSolver credential configuration with successful connection test

Important: Every CapSolver node in your workflows will reference this credential. You only need to create it once โ€” all your solver workflows will share the same credential.

Now you're ready to build your AWS WAF solver workflow!

How to Identify AWS WAF Parameters

Before you can solve an AWS WAF challenge, you need to confirm the target site is using AWS WAF and gather any optional parameters. The easiest way is using the CapSolver Browser Extension combined with manual inspection.

Step 1: Look for AWS WAF Indicators

Navigate to your target website and open DevTools (F12). Look for these telltale signs:

  • Cookies โ€” Check for an aws-waf-token cookie in the Application tab
  • Network requests โ€” Look for requests to captcha.awswaf.com or URLs containing challenge.js

Step 2: Gather Optional Parameters (If Needed)

Most AWS WAF solves only require the websiteURL. However, some sites expose additional parameters that can improve solve accuracy:

Parameter Where to Find Description
awsKey Page source / JS variables The key value returned by the captcha page
awsIv Page source / JS variables The iv value returned by the captcha page
awsContext Page source / JS variables The context value returned by the captcha page
awsChallengeJS Network tab The challenge.js URL (e.g., https://captcha.awswaf.com/.../challenge.js)
awsApiJs Network tab The jsapi.js URL
awsProblemUrl Network tab The problem endpoint URL
awsApiKey Network tab The api_key value from the problem endpoint
awsExistingToken Cookies A previous aws-waf-token if refreshing

Tip: For most sites, you only need websiteURL. Start with just that parameter and add optional ones only if the token isn't being accepted.

For a detailed guide on identifying captcha parameters, check out the official CapSolver documentation.

Workflow: AWS WAF Solver API

This workflow creates a POST API endpoint that accepts AWS WAF parameters and returns a solved cookie token.

AWS WAF solver workflow in n8n

How It Works

The workflow consists of four nodes:

  1. Webhook โ€” Receives incoming POST requests with AWS WAF parameters
  2. AWS WAF โ€” Sends the challenge to CapSolver and waits for a solution
  3. CapSolver Error? โ€” IF node that branches on whether solving failed ($json.error is not empty)
  4. Respond to Webhook โ€” Returns the solution on success, or {"error": "..."} on failure

Node Configuration

1. Webhook Node

Setting Value
HTTP Method POST
Path solver-aws-waf
Respond Response Node

This creates an endpoint at: https://your-n8n-instance.com/webhook/solver-aws-waf

2. CapSolver AWS WAF Node

Parameter Value Description
Operation AWS WAF Must be set to AWS WAF
Type AntiAwsWafTaskProxyLess No proxy needed (default). Use AntiAwsWafTask with a proxy for stricter sites
Website URL {{ $json.body.websiteURL }} The URL of the page with the AWS WAF challenge
awsKey (Optional) The key value returned by the captcha page
awsIv (Optional) The iv value returned by the captcha page
awsContext (Optional) The context value returned by the captcha page
awsChallengeJS (Optional) The challenge.js link
awsApiJs (Optional) The jsapi.js link

Key difference from Turnstile/reCAPTCHA: AWS WAF does not require a websiteKey. Only websiteURL is mandatory. Also select your CapSolver credentials in this node.

3. CapSolver Error? Node (IF)

Setting Value
Condition ={{ $json.error }} is not empty
True branch Routes to the Error Respond to Webhook node
False branch Routes to the Success Respond to Webhook node

This makes the error path explicit on the canvas. The CapSolver node continues on error (onError: continueRegularOutput), so failures arrive here as { "error": "..." } rather than crashing the workflow.

4. Respond to Webhook Nodes

Success branch (false output of CapSolver Error?):

Setting Value
Respond With JSON
Response Body ={{ JSON.stringify($json.data) }}

Error branch (true output of CapSolver Error?):

Setting Value
Respond With JSON
Response Body ={{ JSON.stringify({ error: $json.error }) }}

Error messages follow one of two formats depending on where the failure occurred:

Failure point Format
Task creation rejected (wrong key, no balance, invalid data, etc.) {"error": "Failed to create task: Request failed with status code 400"}
Task created but captcha could not be solved {"error": "Solve failed: <reason>"}
Solve timed out after 120 s {"error": "Get task result timeout: unable to solve within 120000 seconds"}

Note: Task creation failures (wrong API key, zero balance, invalid task data) all surface as the same HTTP 400 message โ€” the n8n node catches the HTTP exception before reading CapSolver's error body.

Common error examples:

json Copy 
{"error": "Failed to create task: Request failed with status code 400"}
{"error": "Solve failed: Invalid parameters"}
{"error": "Get task result timeout: unable to solve within 120000 seconds"}

Test It

Send a POST request to your webhook endpoint:

bash Copy 
curl -X POST https://your-n8n-instance.com/webhook/solver-aws-waf \
  -H "Content-Type: application/json" \
  -d '{
    "websiteURL": "https://example.com/protected-page"
  }'

You can also include optional parameters:

bash Copy 
curl -X POST https://your-n8n-instance.com/webhook/solver-aws-waf \
  -H "Content-Type: application/json" \
  -d '{
    "websiteURL": "https://example.com/protected-page",
    "awsKey": "AQIDAHjc...",
    "awsIv": "CgAHAQABAA...",
    "awsContext": "gxPZ0w9O..."
  }'

Expected Response:

json Copy 
{
  "taskId": "abc123...",
  "solution": {
    "cookie": "aws-waf-token=76b8ee9e-fa6a-4c36-b8e9-0c1d97EXAMPLE..."
  },
  "status": "ready"
}

Important: The solution returns a cookie field (not token or gRecaptchaResponse like other captcha types). The value is a full cookie string like aws-waf-token=LONG_VALUE that you send via the Cookie HTTP header.

API Parameter Reference

The AWS WAF solver API endpoint accepts the following parameters:

Parameter Required Description
websiteURL Yes The URL of the page with the AWS WAF challenge
awsKey No The key value returned by the captcha page
awsIv No The iv value returned by the captcha page
awsContext No The context value returned by the captcha page
awsChallengeJS No The challenge.js link from the captcha page
awsApiJs No The jsapi.js link from the captcha page
awsProblemUrl No The problem endpoint URL
awsApiKey No The api_key value of the problem endpoint
awsExistingToken No A previous aws-waf-token used for last verification

Tip: You can identify the websiteURL by inspecting the page URL. Use DevTools to check for aws-waf-token cookies and network requests to captcha.awswaf.com.

Compared to reCAPTCHA and Turnstile, AWS WAF is simpler in one way โ€” you only need one required parameter (websiteURL), with no site key needed. However, it has more optional parameters for fine-tuning.

Workflow: Submitting an AWS WAF Token to a Website

The API workflow above shows how to get a solved AWS WAF cookie. But what do you actually do with it?

In real-world automation, solving the challenge is only half the job. You need to submit the cookie to the target website โ€” exactly as a browser would โ€” to unlock the data or action behind the AWS WAF protection.

Here's the general pattern:

  1. Solve the challenge -> Get the cookie from CapSolver (solution.cookie)
  2. Submit the cookie -> Send it to the target website via the Cookie HTTP header
  3. Verify the response -> Check if the website accepted the cookie
  4. Process the result -> Extract the data you need

Example: Solving & Submitting AWS WAF

Example: https://example.com/ โ€” An AWS WAF-protected website

Workflow Flow

Copy 
Manual Trigger -> CapSolver AWS WAF -> HTTP GET Request (with Cookie header) -> IF (check success) -> Valid / Invalid

How It Works

  1. Manual Trigger โ€” Starts the workflow manually (click "Execute workflow"). You can replace this with any trigger โ€” Webhook, Schedule, App Event, etc.
  2. CapSolver AWS WAF โ€” Solves the AWS WAF challenge:
    • Operation: AWS WAF
    • Website URL: https://example.com/protected-page
    • Type: AntiAwsWafTaskProxyLess
  3. HTTP Request โ€” Sends a request to the protected page with the solved cookie:
    • The cookie is sent in the Cookie header: ={{ $json.data.solution.cookie }}
    • This is what a browser does โ€” it stores the aws-waf-token cookie and sends it with every subsequent request
  4. IF Node โ€” Checks if the response indicates success (e.g., status code < 400, expected content present)
  5. Valid / Invalid โ€” Routes to appropriate handling. On the Valid branch, use the HTML node to extract specific elements (e.g., product data, account info)

Key difference from Turnstile/reCAPTCHA: AWS WAF tokens are submitted as cookies, not form fields. The solved value goes in the Cookie HTTP header, not in a g-recaptcha-response or cf-turnstile-response field. This means you can use GET requests (not just POST) to access protected pages.

Workflow: Use-Case Examples

The solver API and submission example above show the core pattern: solve the AWS WAF challenge, submit the cookie, process the result. The following workflows extend this pattern to production-ready use cases โ€” each with dual triggers (schedule + webhook), persistent state tracking, and structured output.

Workflow Purpose
AWS WAF Scraping โ€” Price & Product Details โ€” CapSolver + Schedule + Webhook Scrapes price and product name every 6 hours, compares against previous values stored in staticData, alerts on changes
AWS WAF Account Login โ€” CapSolver + Schedule + Webhook Logs into your own account on an AWS WAF-protected site by solving first, then POSTing credentials with the cookie

Example 1: Scraping

This workflow scrapes a product page every 6 hours (schedule) or on demand (webhook), extracts the price using the HTML node, and compares it against the previously stored value.

Schedule path:

Copy 
Every 6 Hours -> Solve AWS WAF -> Fetch Product Page -> Extract Data
  -> Compare Data -> Data Changed? -> Build Alert / No Change

Key behaviors:

  • The cookie is sent as a Cookie header (this is the correct way to submit AWS WAF tokens โ€” not as a form field)
  • The HTML node extracts price and product name via CSS selectors (.product-price, h1)
  • $workflow.staticData.lastPrice persists the previous price across executions
  • Price comparison detects both drops (severity: deal) and increases (severity: info)

Example 2: Account Login

This workflow automates login to an AWS WAF-protected site. A Set Login Config node centralizes all parameters โ€” [Schedule] for the schedule path. Edit the config node to configure your target site.

Schedule path:

Copy 
Every 24 Hours -> Set Login Config -> Solve Captcha -> Submit Login
  -> Login Successful? -> Mark Login Success / Mark Login Failed

Error handling: If CapSolver fails, the execution stops and is marked as failed in n8n. Check Executions to see the error, or configure n8n's Error Workflow to get notified automatically.

Key behaviors:

  • Uses AntiAwsWafTaskProxyLess โ€” no proxy needed for most sites
  • No websiteKey or tokenFieldName โ€” AWS WAF only needs websiteURL, and the token is submitted as a Cookie header (not a form field)
  • Form fields for username/password are submitted normally via form-urlencoded POST โ€” only the AWS WAF cookie is added as a header
  • The Login Successful? check evaluates both statusCode < 400 and the presence of a configurable successMarker in the response body
  • Webhook path reads parameters from the request body for on-demand execution
  • Webhook path returns the result as JSON via Respond to Webhook

Conclusion

You've learned how to build AWS WAF-solving APIs and production-ready scraping workflows using n8n and CapSolver โ€” no traditional coding required.

In this guide, we covered:

  • API solver endpoints for AWS WAF using webhook-based workflows
  • Use-case examples โ€” scraping and account login โ€” showing how to submit solved cookies and process protected data
  • How to identify AWS WAF parameters using DevTools
  • Best practices for cookie-based token handling, error management, and production use

The key takeaway: AWS WAF tokens work differently from reCAPTCHA and Turnstile โ€” they are submitted as cookies via the Cookie HTTP header, not as form fields. Only websiteURL is required (no site key needed), and the solution returns solution.cookie instead of solution.token.

Tip: These workflows use Schedule + Webhook triggers, but you can swap the trigger node to any n8n trigger โ€” manual, app event, form submission, etc. After fetching data, use n8n's built-in nodes to save results to Google Sheets, databases, cloud storage, or send alerts via Telegram/Slack/Email.

Frequently Asked Questions

What is AWS WAF?

AWS WAF (Web Application Firewall) is Amazon's web security service that protects websites from bots, scrapers, and other automated threats. It can present invisible CAPTCHA challenges that require an aws-waf-token cookie to bypass. Many enterprise and e-commerce sites use it.

How much does it cost to solve an AWS WAF challenge?

Pricing varies by task complexity. Check the CapSolver pricing page for current AWS WAF rates.

How long does it take to solve an AWS WAF challenge?

Most AWS WAF challenges are solved in 5-30 seconds depending on the site's configuration and the parameters provided. Providing optional parameters like awsKey, awsIv, and awsContext can improve solve speed and reliability.

Can I use these workflows with n8n Cloud?

Yes! These workflows work with both self-hosted n8n and n8n Cloud. The CapSolver node is already available as an official integration โ€” just add your API credentials.
