How to Solve reCAPTCHA v2/v3 Using CapSolver and n8n

Lucas Mitchell

Automation Engineer

If you've ever tried to automate web interactions, you've almost certainly run into reCAPTCHA — Google's challenge system that blocks bots from accessing websites. Whether you're building scrapers, testing web applications, or automating repetitive tasks, reCAPTCHA can bring your entire workflow to a halt.

What if you could solve reCAPTCHA automatically inside your n8n workflows — whether you're building a reusable solver API, scraping a captcha-protected site, or automating a login form — 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 reCAPTCHA v2, v2 Invisible, and v3 challenges on demand — either as a standalone API endpoint or as a step inside any automation workflow.

What you'll build:

Solver API — a reusable endpoint your other tools can call:

A reCAPTCHA solver API (works for v2, v2 Invisible, and v3 — just change the Operation in the CapSolver node)

Direct-use workflows — CapSolver embedded as a step inside larger automations:

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

What is reCAPTCHA?

reCAPTCHA is Google's bot detection system used by millions of websites. There are three main versions you'll encounter:

reCAPTCHA v2 — Checkbox ("I'm not a robot") + image challenges
reCAPTCHA v2 Invisible — No visible checkbox, triggers automatically in the background
reCAPTCHA v3 — Completely invisible, assigns a score (0.0–1.0) based on behavior

Understanding which version a website uses is critical — each one requires slightly different parameters when solving.

Prerequisites

Before getting started, make sure you have the following:

An n8n instance — Either self-hosted or n8n Cloud
A CapSolver account — Sign up here and get your API key
The CapSolver n8n node — Already available as an official node in n8n (no installation needed)
CapSolver browser extension (optional but recommended) — For identifying captcha parameters on target websites

Important: Make sure you have sufficient balance in your CapSolver account. reCAPTCHA solving tasks consume credits based on the captcha type.

Setting Up CapSolver in n8n

CapSolver is available as an official integration in n8n — 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

Click Create credential (top right)
Search for "CapSolver" and select CapSolver API
Enter your API Key — copy it directly from the CapSolver Dashboard
Leave Allowed HTTP Request Domains set to All (default)
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 — all your solver workflows will share the same credential.

Now you're ready to build your reCAPTCHA solver workflow!

How to Identify reCAPTCHA Parameters

Before you can solve a reCAPTCHA, you need to know its parameters — specifically the websiteURL and websiteKey (also called the site key). The easiest way to find these is using the CapSolver Browser Extension.

Step 1: Install the CapSolver Extension

Download and install the CapSolver extension from the Chrome Web Store or Firefox Add-ons.

Step 2: Open the CAPTCHA Detector

Navigate to the target website
Press F12 to open Developer Tools
Find the "CapSolver Captcha Detector" tab in DevTools

Step 3: Trigger the CAPTCHA

With the detector panel open, interact with the page to trigger the reCAPTCHA. The extension will automatically detect and display all relevant parameters:

Website URL — The page URL hosting the CAPTCHA
Website Key (Site Key) — The public key identifier for the captcha
pageAction — The specific action being verified (v3)
isInvisible — Whether it's an invisible reCAPTCHA
isEnterprise — Whether it uses reCAPTCHA Enterprise
apiDomain — The API endpoint being used (e.g., recaptcha.net)

Detected reCAPTCHA parameters in CapSolver extension

Tip: The extension generates a JSON output showing exactly how to format these parameters for your solving request. This saves you from having to manually inspect the page source.

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

Workflow: reCAPTCHA Solver API

This workflow creates a POST endpoint that accepts reCAPTCHA parameters and returns a solved token. The same 4-node structure works for all reCAPTCHA types — just change the Operation in the CapSolver node.

How It Works

Webhook — Receives POST requests with captcha parameters
CapSolver — Solves the challenge using the configured Operation
CapSolver Error? — IF node that branches on whether solving failed ($json.error is not empty)
Respond to Webhook — Returns the solution on success, or {"error": "..."} on failure

Choosing Your reCAPTCHA Type

Type	Operation to select	Extra parameter
v2 Standard	`reCAPTCHA v2`	—
v2 Invisible	`reCAPTCHA v2`	Set Is Invisible to `true` in the node
v3	`reCAPTCHA v3`	Add pageAction — must match the target site's configured action (e.g., `login`, `submit`)

The workflow below uses reCAPTCHA v2 as the default. Open the CapSolver node and change the Operation dropdown to switch types. No other structural changes are needed.

Node Configuration

1. Webhook Node

Setting	Value
HTTP Method	`POST`
Path	`solver-recaptcha`
Respond	`Response Node`

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

2. CapSolver Node

Parameter	Value	Description
Operation	`reCAPTCHA v2`	Change this to `reCAPTCHA v3` for v3; for v2 Invisible, keep `reCAPTCHA v2` and set `Is Invisible` to `true`
Website URL	`={{ $json.body.websiteURL }}`	The URL of the page with the captcha
Website Key	`={{ $json.body.websiteKey }}`	The reCAPTCHA site key
Page Action	`={{ $json.body.pageAction \|\| '' }}`	Required for v3 — must match the site's configured action
Is Invisible	`={{ $json.body.isInvisible \|\| false }}`	Set to `true` for v2 Invisible
API Domain	`={{ $json.body.apiDomain \|\| '' }}`	Optional — custom API domain (e.g., `recaptcha.net`)
Enterprise Payload	`={{ $json.body.enterprisePayload \|\| '' }}`	Optional — additional payload for reCAPTCHA Enterprise
Is Session	`={{ $json.body.isSession \|\| false }}`	Optional — enable session-based solving
Task Type	`={{ $json.body.taskType \|\| 'ReCaptchaV2TaskProxyLess' }}`	CapSolver task type — see reference below. Defaults to `ReCaptchaV2TaskProxyLess`
Proxy	`={{ $json.body.proxy \|\| '' }}`	Only used when the selected Task Type requires a proxy (non-`ProxyLess` types). Leave empty or omit for `ProxyLess` task types. Format: `ip:port:user:pass`

Also select your CapSolver credentials in the node.

reCAPTCHA Task Type Reference:

Task Type	Proxy Required	Notes
`ReCaptchaV2TaskProxyLess`	No	v2 default
`ReCaptchaV2Task`	Yes	v2 with proxy
`ReCaptchaV2EnterpriseTaskProxyLess`	No	Enterprise v2, no proxy
`ReCaptchaV2EnterpriseTask`	Yes	Enterprise v2, requires proxy
`ReCaptchaV3TaskProxyLess`	No	v3 default
`ReCaptchaV3Task`	Yes	v3 with proxy
`ReCaptchaV3EnterpriseTaskProxyLess`	No	Enterprise v3, no proxy
`ReCaptchaV3EnterpriseTask`	Yes	Enterprise v3, requires proxy

Proxy: Only applicable for non-ProxyLess task types (e.g., ReCaptchaV2Task, ReCaptchaV3EnterpriseTask). When using a ProxyLess task type, the proxy field is ignored — CapSolver uses its own infrastructure. When using a non-ProxyLess type, you must supply a proxy.

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. You can attach additional nodes to the true branch (logging, alerts, retries) without touching the success path.

4. Respond to Webhook Nodes

Success branch (false output of CapSolver Error?):

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

Test It

Send a POST request to your webhook endpoint:

bash Copy

curl -X POST https://your-n8n-instance.com/webhook/solver-recaptcha \
  -H "Content-Type: application/json" \
  -d '{
    "websiteURL": "https://example.com/login",
    "websiteKey": "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-",
    "taskType": "ReCaptchaV2TaskProxyLess"
  }'

Task type must match the node's Operation. Each deployed workflow is configured for a specific reCAPTCHA version via the Operation field in the CapSolver node (reCAPTCHA v2 or reCAPTCHA v3). Only task types for that version are valid — sending a v3 task type to a v2 workflow (or vice versa) will not work. Note: v2 Invisible uses the same reCAPTCHA v2 operation as standard v2 — the difference is the isInvisible parameter, not the operation.

For reCAPTCHA v3, also add "pageAction": "login" (or whatever action the site uses) to the request body, and use a v3 task type (e.g., "taskType": "ReCaptchaV3TaskProxyLess").

Expected Response:

json Copy

{
  "taskId": "abc123...",
  "solution": {
    "gRecaptchaResponse": "03AGdBq24PBCb..."
  },
  "status": "ready"
}

Import This Workflow

Copy the JSON below and import it into n8n via Menu → Import from JSON. Then change the Operation in the CapSolver node to your target reCAPTCHA type.

Workflow: Submitting Tokens to Websites

So far, the API workflows above show how to get a solved captcha token. But what do you actually do with it?

In real-world automation, solving the captcha is only half the job. You need to submit the token to the target website — exactly as a browser would — to unlock the data or action behind the captcha.

Here's the general pattern:

Solve the captcha → Get the gRecaptchaResponse token from CapSolver
Submit the token → Send it to the target website via an HTTP Request (usually as a g-recaptcha-response form field or URL parameter)
Verify the response → Check if the website accepted the token and returned the expected data
Process the result → Extract the data you need

Example: Solving & Submitting reCAPTCHA v2

Example: example.com

Workflow Flow

Copy

Manual Trigger → CapSolver reCAPTCHA v2 → HTTP POST Request → IF (check success) → Valid / Invalid

How It Works

Manual Trigger — Starts the workflow manually (click "Execute workflow"). You can replace this with any trigger — Webhook, Schedule, App Event, etc.
CapSolver reCAPTCHA v2 — Solves the captcha for the demo page:
- Website URL: https://example.com
- Website Key: YOUR_SITE_KEY
HTTP POST Request — Submits the solved token to the same URL as a form POST:
- The token is sent in the g-recaptcha-response form field
- This is exactly what a browser does when you click "Submit" after solving the captcha
IF Node — Checks if the response HTML contains "recaptcha-success", meaning the captcha was accepted
Valid / Invalid — The IF node routes to the Valid branch on success (where you extract the data you need, e.g., with the HTML node for product listings, form results, etc.) or the Invalid branch on failure (where you handle the error)

Key concept: Every website handles token submission differently. In this demo, the token goes in a g-recaptcha-response form field via POST — but other sites may expect it as a URL parameter, in a JSON body, or through a completely different endpoint. Always inspect the site's actual form submission (using DevTools Network tab) to see exactly how the token needs to be sent.

Adapting for other reCAPTCHA types: This same pattern works for v2 Invisible and v3. For v2 Invisible, set isInvisible: true in the CapSolver node. For v3, change the Operation to reCAPTCHA v3 and add the pageAction parameter. The HTTP Request submission step will differ per site — always inspect the actual form submission in DevTools.

Workflow: Use-Case Examples

The solver API and scraping examples above show the core pattern: solve the captcha, submit the token, process the result. The following workflows extend this pattern to production-ready use cases — each with dual triggers (schedule + webhook), persistent state tracking, and structured output.

Workflow	Purpose
`reCAPTCHA Scraping — Price & Product Details — CapSolver + Schedule + Webhook`	Scrapes price and product name every 6 hours, compares against previous values stored in `staticData`, alerts on changes
`reCAPTCHA Account Login — CapSolver + Schedule + Webhook`	Logs into your own account on a captcha-protected site by solving first, then POSTing credentials with the token

Example 1: Scraping — Price & Product Details

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 reCAPTCHA v3 → Fetch Product Page → Extract Data
  → Compare Data → Data Changed? → Build Alert / No Change

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 reCAPTCHA v3 with a pageAction parameter (configurable)
The token is sent as an x-recaptcha-token header (adapt to your site's expected format)
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)
Task type is ReCaptchaV3TaskProxyLess (hardcoded) — edit the Solve reCAPTCHA v3 node directly to change the task type or proxy

This workflow automates login to a captcha-protected site. A Set Login Config node centralizes all parameters — [Schedule] for the schedule path and [Webhook] for the on-demand webhook path. Edit the appropriate config node to configure each path.

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:

Defaults to reCAPTCHA v2 (ReCaptchaV2TaskProxyLess) — change taskType in Set Login Config [Schedule] or Set Login Config [Webhook] for the respective path; change the Operation in the Solve Captcha node if switching between v2 and v3
Form fields are hardcoded as email, password, and g-recaptcha-response — edit the Submit Login node directly to match your target site's field names
The Login Successful? check evaluates both statusCode < 400 and the presence of a configurable successMarker in the response body
Webhook path uses Set Login Config [Webhook] with the same hardcoded placeholder values — edit that node to configure the webhook on-demand path
Webhook path returns the result as JSON via Respond to Webhook

Conclusion

You've learned how to build reCAPTCHA-solving APIs and production-ready scraping workflows using n8n and CapSolver — no traditional coding required.

In this guide, we covered:

API solver endpoints for reCAPTCHA v2, v2 Invisible, and v3 using webhook-based workflows
Use-case examples — scraping and account login — showing how to submit solved tokens and process protected data
How to identify captcha parameters using the CapSolver browser extension
Best practices for token handling, error management, and production use

The key takeaway: solving the captcha is only half the job — you also need to submit the token to the target website to unlock the protected data.

Tip: These workflows use Schedule + Webhook triggers, but you can swap the trigger node to any n8n trigger — 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

How much does it cost to solve a reCAPTCHA?

Pricing varies by captcha type. reCAPTCHA v2 typically costs around $1-3 per 1,000 solves. Check the CapSolver pricing page for current rates.

How long does it take to solve a reCAPTCHA?

Most reCAPTCHA v2 challenges are solved in 5-20 seconds. reCAPTCHA v3 is typically faster since there's no image challenge involved.

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 — just add your API credentials.

How do I find the reCAPTCHA site key for a website?

The easiest method is using the CapSolver browser extension — open DevTools, go to the "CapSolver Captcha Detector" tab, and trigger the captcha. The extension will display all parameters automatically. Alternatively, you can search the page source for data-sitekey or render= in the reCAPTCHA script URL.

What's the difference between reCAPTCHA v2 and v2 Invisible?

Both use the same underlying technology, but v2 shows a visible checkbox ("I'm not a robot") while v2 Invisible runs in the background without any visible widget. When solving, the only difference is setting isInvisible: true.

CapSolver returned a token but the website still rejected it — why?

Several things can cause this. First, tokens expire quickly — make sure you're submitting the token immediately. Second, verify you're sending the token to the right place: inspect the actual network request the browser makes when you submit the form (DevTools → Network tab) and confirm the field name, request method, and endpoint all match what you've configured in n8n. Third, some sites require additional parameters like enterprisePayload or specific cookies and headers — use the CapSolver extension to check if any of these apply. If the token is still rejected, contact CapSolver support for site-specific help.

How to Solve reCAPTCHA v2/v3 Using CapSolver and n8n

Lucas Mitchell

Automation Engineer

What you'll build:

Solver API — a reusable endpoint your other tools can call:

A reCAPTCHA solver API (works for v2, v2 Invisible, and v3 — just change the Operation in the CapSolver node)

Direct-use workflows — CapSolver embedded as a step inside larger automations:

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

What is reCAPTCHA?

reCAPTCHA is Google's bot detection system used by millions of websites. There are three main versions you'll encounter:

Understanding which version a website uses is critical — each one requires slightly different parameters when solving.

Prerequisites

Before getting started, make sure you have the following:

An n8n instance — Either self-hosted or n8n Cloud
A CapSolver account — Sign up here and get your API key
The CapSolver n8n node — Already available as an official node in n8n (no installation needed)
CapSolver browser extension (optional but recommended) — For identifying captcha parameters on target websites

Important: Make sure you have sufficient balance in your CapSolver account. reCAPTCHA solving tasks consume credits based on the captcha type.

Setting Up CapSolver in n8n

CapSolver is available as an official integration in n8n — 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

Click Create credential (top right)
Search for "CapSolver" and select CapSolver API
Enter your API Key — copy it directly from the CapSolver Dashboard
Leave Allowed HTTP Request Domains set to All (default)
Click Save

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

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

Now you're ready to build your reCAPTCHA solver workflow!

How to Identify reCAPTCHA Parameters

Step 1: Install the CapSolver Extension

Download and install the CapSolver extension from the Chrome Web Store or Firefox Add-ons.

Step 2: Open the CAPTCHA Detector

Navigate to the target website
Press F12 to open Developer Tools
Find the "CapSolver Captcha Detector" tab in DevTools

Step 3: Trigger the CAPTCHA

With the detector panel open, interact with the page to trigger the reCAPTCHA. The extension will automatically detect and display all relevant parameters:

Website URL — The page URL hosting the CAPTCHA
Website Key (Site Key) — The public key identifier for the captcha
pageAction — The specific action being verified (v3)
isInvisible — Whether it's an invisible reCAPTCHA
isEnterprise — Whether it uses reCAPTCHA Enterprise
apiDomain — The API endpoint being used (e.g., recaptcha.net)

Tip: The extension generates a JSON output showing exactly how to format these parameters for your solving request. This saves you from having to manually inspect the page source.

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

Workflow: reCAPTCHA Solver API

How It Works

Webhook — Receives POST requests with captcha parameters
CapSolver — Solves the challenge using the configured Operation
CapSolver Error? — IF node that branches on whether solving failed ($json.error is not empty)
Respond to Webhook — Returns the solution on success, or {"error": "..."} on failure

Choosing Your reCAPTCHA Type

Type	Operation to select	Extra parameter
v2 Standard	`reCAPTCHA v2`	—
v2 Invisible	`reCAPTCHA v2`	Set Is Invisible to `true` in the node
v3	`reCAPTCHA v3`	Add pageAction — must match the target site's configured action (e.g., `login`, `submit`)

The workflow below uses reCAPTCHA v2 as the default. Open the CapSolver node and change the Operation dropdown to switch types. No other structural changes are needed.

Node Configuration

1. Webhook Node

Setting	Value
HTTP Method	`POST`
Path	`solver-recaptcha`
Respond	`Response Node`

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

2. CapSolver Node

Parameter	Value	Description
Operation	`reCAPTCHA v2`	Change this to `reCAPTCHA v3` for v3; for v2 Invisible, keep `reCAPTCHA v2` and set `Is Invisible` to `true`
Website URL	`={{ $json.body.websiteURL }}`	The URL of the page with the captcha
Website Key	`={{ $json.body.websiteKey }}`	The reCAPTCHA site key
Page Action	`={{ $json.body.pageAction \|\| '' }}`	Required for v3 — must match the site's configured action
Is Invisible	`={{ $json.body.isInvisible \|\| false }}`	Set to `true` for v2 Invisible
API Domain	`={{ $json.body.apiDomain \|\| '' }}`	Optional — custom API domain (e.g., `recaptcha.net`)
Enterprise Payload	`={{ $json.body.enterprisePayload \|\| '' }}`	Optional — additional payload for reCAPTCHA Enterprise
Is Session	`={{ $json.body.isSession \|\| false }}`	Optional — enable session-based solving
Task Type	`={{ $json.body.taskType \|\| 'ReCaptchaV2TaskProxyLess' }}`	CapSolver task type — see reference below. Defaults to `ReCaptchaV2TaskProxyLess`
Proxy	`={{ $json.body.proxy \|\| '' }}`	Only used when the selected Task Type requires a proxy (non-`ProxyLess` types). Leave empty or omit for `ProxyLess` task types. Format: `ip:port:user:pass`

Also select your CapSolver credentials in the node.

reCAPTCHA Task Type Reference:

Task Type	Proxy Required	Notes
`ReCaptchaV2TaskProxyLess`	No	v2 default
`ReCaptchaV2Task`	Yes	v2 with proxy
`ReCaptchaV2EnterpriseTaskProxyLess`	No	Enterprise v2, no proxy
`ReCaptchaV2EnterpriseTask`	Yes	Enterprise v2, requires proxy
`ReCaptchaV3TaskProxyLess`	No	v3 default
`ReCaptchaV3Task`	Yes	v3 with proxy
`ReCaptchaV3EnterpriseTaskProxyLess`	No	Enterprise v3, no proxy
`ReCaptchaV3EnterpriseTask`	Yes	Enterprise v3, requires proxy

Proxy: Only applicable for non-ProxyLess task types (e.g., ReCaptchaV2Task, ReCaptchaV3EnterpriseTask). When using a ProxyLess task type, the proxy field is ignored — CapSolver uses its own infrastructure. When using a non-ProxyLess type, you must supply a proxy.

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

4. Respond to Webhook Nodes

Success branch (false output of CapSolver Error?):

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

Test It

Send a POST request to your webhook endpoint:

bash Copy

curl -X POST https://your-n8n-instance.com/webhook/solver-recaptcha \
  -H "Content-Type: application/json" \
  -d '{
    "websiteURL": "https://example.com/login",
    "websiteKey": "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-",
    "taskType": "ReCaptchaV2TaskProxyLess"
  }'

Task type must match the node's Operation. Each deployed workflow is configured for a specific reCAPTCHA version via the Operation field in the CapSolver node (reCAPTCHA v2 or reCAPTCHA v3). Only task types for that version are valid — sending a v3 task type to a v2 workflow (or vice versa) will not work. Note: v2 Invisible uses the same reCAPTCHA v2 operation as standard v2 — the difference is the isInvisible parameter, not the operation.

For reCAPTCHA v3, also add "pageAction": "login" (or whatever action the site uses) to the request body, and use a v3 task type (e.g., "taskType": "ReCaptchaV3TaskProxyLess").

Expected Response:

json Copy

{
  "taskId": "abc123...",
  "solution": {
    "gRecaptchaResponse": "03AGdBq24PBCb..."
  },
  "status": "ready"
}

Import This Workflow

Copy the JSON below and import it into n8n via Menu → Import from JSON. Then change the Operation in the CapSolver node to your target reCAPTCHA type.

Workflow: Submitting Tokens to Websites

So far, the API workflows above show how to get a solved captcha token. But what do you actually do with it?

Here's the general pattern:

Solve the captcha → Get the gRecaptchaResponse token from CapSolver
Submit the token → Send it to the target website via an HTTP Request (usually as a g-recaptcha-response form field or URL parameter)
Verify the response → Check if the website accepted the token and returned the expected data
Process the result → Extract the data you need

Example: Solving & Submitting reCAPTCHA v2

Example: example.com

Workflow Flow

Copy

Manual Trigger → CapSolver reCAPTCHA v2 → HTTP POST Request → IF (check success) → Valid / Invalid

How It Works

Manual Trigger — Starts the workflow manually (click "Execute workflow"). You can replace this with any trigger — Webhook, Schedule, App Event, etc.
CapSolver reCAPTCHA v2 — Solves the captcha for the demo page:
- Website URL: https://example.com
- Website Key: YOUR_SITE_KEY
HTTP POST Request — Submits the solved token to the same URL as a form POST:
- The token is sent in the g-recaptcha-response form field
- This is exactly what a browser does when you click "Submit" after solving the captcha
IF Node — Checks if the response HTML contains "recaptcha-success", meaning the captcha was accepted
Valid / Invalid — The IF node routes to the Valid branch on success (where you extract the data you need, e.g., with the HTML node for product listings, form results, etc.) or the Invalid branch on failure (where you handle the error)

Key concept: Every website handles token submission differently. In this demo, the token goes in a g-recaptcha-response form field via POST — but other sites may expect it as a URL parameter, in a JSON body, or through a completely different endpoint. Always inspect the site's actual form submission (using DevTools Network tab) to see exactly how the token needs to be sent.

Adapting for other reCAPTCHA types: This same pattern works for v2 Invisible and v3. For v2 Invisible, set isInvisible: true in the CapSolver node. For v3, change the Operation to reCAPTCHA v3 and add the pageAction parameter. The HTTP Request submission step will differ per site — always inspect the actual form submission in DevTools.

Workflow: Use-Case Examples

Workflow	Purpose
`reCAPTCHA Scraping — Price & Product Details — CapSolver + Schedule + Webhook`	Scrapes price and product name every 6 hours, compares against previous values stored in `staticData`, alerts on changes
`reCAPTCHA Account Login — CapSolver + Schedule + Webhook`	Logs into your own account on a captcha-protected site by solving first, then POSTing credentials with the token

Example 1: Scraping — Price & Product Details

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 reCAPTCHA v3 → Fetch Product Page → Extract Data
  → Compare Data → Data Changed? → Build Alert / No Change

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 reCAPTCHA v3 with a pageAction parameter (configurable)
The token is sent as an x-recaptcha-token header (adapt to your site's expected format)
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)
Task type is ReCaptchaV3TaskProxyLess (hardcoded) — edit the Solve reCAPTCHA v3 node directly to change the task type or proxy

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:

Defaults to reCAPTCHA v2 (ReCaptchaV2TaskProxyLess) — change taskType in Set Login Config [Schedule] or Set Login Config [Webhook] for the respective path; change the Operation in the Solve Captcha node if switching between v2 and v3
Form fields are hardcoded as email, password, and g-recaptcha-response — edit the Submit Login node directly to match your target site's field names
The Login Successful? check evaluates both statusCode < 400 and the presence of a configurable successMarker in the response body
Webhook path uses Set Login Config [Webhook] with the same hardcoded placeholder values — edit that node to configure the webhook on-demand path
Webhook path returns the result as JSON via Respond to Webhook

Conclusion

You've learned how to build reCAPTCHA-solving APIs and production-ready scraping workflows using n8n and CapSolver — no traditional coding required.

In this guide, we covered:

API solver endpoints for reCAPTCHA v2, v2 Invisible, and v3 using webhook-based workflows
Use-case examples — scraping and account login — showing how to submit solved tokens and process protected data
How to identify captcha parameters using the CapSolver browser extension
Best practices for token handling, error management, and production use

The key takeaway: solving the captcha is only half the job — you also need to submit the token to the target website to unlock the protected data.

Tip: These workflows use Schedule + Webhook triggers, but you can swap the trigger node to any n8n trigger — 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

How much does it cost to solve a reCAPTCHA?

Pricing varies by captcha type. reCAPTCHA v2 typically costs around $1-3 per 1,000 solves. Check the CapSolver pricing page for current rates.

How long does it take to solve a reCAPTCHA?

Most reCAPTCHA v2 challenges are solved in 5-20 seconds. reCAPTCHA v3 is typically faster since there's no image challenge involved.

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 — just add your API credentials.

How do I find the reCAPTCHA site key for a website?

What's the difference between reCAPTCHA v2 and v2 Invisible?

CapSolver returned a token but the website still rejected it — why?
