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.

But what if you could build your own reCAPTCHA-solving API — one that receives a captcha challenge and returns a valid solution, 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 create powerful API endpoints that solve reCAPTCHA v2, v2 Invisible, and v3 challenges on demand.

What you'll build:

A reCAPTCHA v2 solver API
A reCAPTCHA v2 Invisible solver API
A reCAPTCHA v3 solver API
Real-world scraping examples that solve captchas, submit tokens to websites, and verify the results

What is reCAPTCHA?

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

Feature	reCAPTCHA v2	reCAPTCHA v2 Invisible	reCAPTCHA v3
User interaction	Checkbox ("I'm not a robot") + image challenges	No visible checkbox — triggers automatically	No interaction at all
How it works	User must click and possibly solve image puzzles	Runs in the background, only shows challenges if suspicious	Assigns a score (0.0 to 1.0) based on behavior
Visibility	Always visible on the page	Hidden until triggered	Completely invisible
Common use case	Login forms, sign-ups	Form submissions, checkout pages	Continuous monitoring, scoring user actions
Site key visible?	Yes	Yes	Yes

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 solver workflows!

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 1: reCAPTCHA v2 Solver API

This workflow creates a POST API endpoint that accepts reCAPTCHA v2 parameters and returns a solved token.

How It Works

The workflow consists of three nodes:

Webhook — Receives incoming POST requests with captcha parameters
CapSolver reCAPTCHA v2 — Sends the challenge to CapSolver and waits for a solution
Respond to Webhook — Returns the solution as a JSON response

Node Configuration

1. Webhook Node

Setting	Value
HTTP Method	`POST`
Path	`solver-recaptcha-v2`
Response Mode	`Response Node`

This creates an endpoint at: https://your-n8n-instance.com/webhook/solver-recaptcha-v2

2. CapSolver reCAPTCHA v2 Node

Parameter	Value	Description
Type	`ReCaptchaV2TaskProxyLess`	Select in n8n based on the target site (see available types below)
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 \|\| '' }}`	(Optional) The action parameter
Enterprise Payload	`{{ $json.body.enterprisePayload \|\| '' }}`	(Optional) For Enterprise reCAPTCHA
Is Invisible	`{{ $json.body.isInvisible \|\| false }}`	(Optional) Set to `true` for invisible
Is Session	`{{ $json.body.isSession \|\| false }}`	(Optional) Session-based solving
API Domain	`{{ $json.body.apiDomain \|\| '' }}`	(Optional) Custom API domain

Available types for reCAPTCHA v2 (select in n8n dashboard):

Type	When to use
`ReCaptchaV2TaskProxyLess`	Standard reCAPTCHA v2 — works for most sites (no proxy needed)
`ReCaptchaV2EnterpriseTask`	reCAPTCHA Enterprise — requires a proxy (`ip:port:user:pass`)
`ReCaptchaV2EnterpriseTaskProxyLess`	reCAPTCHA Enterprise without proxy

Select the correct type directly in the n8n node configuration. If you choose a type that requires a proxy (e.g., ReCaptchaV2EnterpriseTask), a proxy field will appear — enter your proxy in ip:port:user:pass format. Use the CapSolver extension to detect if the site uses Enterprise reCAPTCHA. Also select your CapSolver credentials in this node.

3. Respond to Webhook Node

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

This returns the full CapSolver response, including the gRecaptchaResponse token.

Test It

Send a POST request to your webhook endpoint:

bash Copy

curl -X POST https://your-n8n-instance.com/webhook/solver-recaptcha-v2 \
  -H "Content-Type: application/json" \
  -d '{
    "websiteURL": "https://example.com/login",
    "websiteKey": "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-"
  }'

Expected Response:

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

Workflow 2: reCAPTCHA v2 Invisible Solver API

reCAPTCHA v2 Invisible works just like standard v2, except the captcha runs in the background without showing a checkbox. The key difference in your solver configuration is setting isInvisible: true.

reCAPTCHA v2 Invisible solver workflow in n8n

How It Works

The workflow has the same three-node structure:

Webhook — Receives POST requests at /solve-recaptcha-v2-invisible
CapSolver reCAPTCHA v2 Invisible — Solves with isInvisible flag enabled
Respond to Webhook — Returns a clean JSON response with the solution token

Node Configuration

1. Webhook Node

Setting	Value
HTTP Method	`POST`
Path	`solve-recaptcha-v2-invisible`
Response Mode	`Response Node`

2. CapSolver reCAPTCHA v2 Invisible Node

Parameter	Value	Description
Type	`ReCaptchaV2TaskProxyLess`	Select in n8n based on the target site (see available types below)
Website URL	`{{ $json.body.websiteURL }}`	The URL of the page with the captcha
Website Key	`{{ $json.body.websiteKey }}`	The reCAPTCHA site key
Is Invisible	`true` (hardcoded)	Always `true` for this endpoint
Page Action	`{{ $json.body.pageAction \|\| '' }}`	(Optional) The action parameter
Enterprise Payload	`{{ $json.body.enterprisePayload \|\| '' }}`	(Optional) For Enterprise reCAPTCHA
Is Session	`{{ $json.body.isSession \|\| false }}`	(Optional) Session-based solving
API Domain	`{{ $json.body.apiDomain \|\| '' }}`	(Optional) Custom API domain

Available types for reCAPTCHA v2 Invisible (select in n8n dashboard):

Type	When to use
`ReCaptchaV2TaskProxyLess`	Standard invisible reCAPTCHA — works for most sites (no proxy needed)
`ReCaptchaV2EnterpriseTask`	Invisible Enterprise reCAPTCHA — requires a proxy (`ip:port:user:pass`)
`ReCaptchaV2EnterpriseTaskProxyLess`	Invisible Enterprise reCAPTCHA without proxy

Key difference: Unlike the v2 workflow, isInvisible is hardcoded to true here since this endpoint is specifically for invisible captchas. Select the correct type directly in the n8n node — if you choose a type that requires a proxy, a proxy field will appear where you enter it in ip:port:user:pass format.

3. Respond to Webhook Node

This node returns a cleaner, structured response:

  success: true,
  solution: $json.data.solution.gRecaptchaResponse,
  taskId: $json.data.taskId
}) }}

Workflow 3: reCAPTCHA v3 Solver API

reCAPTCHA v3 is different from v2 because it doesn't present any challenge to the user. Instead, it assigns a score between 0.0 (likely a bot) and 1.0 (likely a human) based on user behavior. Websites set their own threshold — for example, a score above 0.5 might be required to proceed.

When solving reCAPTCHA v3, the key additional parameter is the pageAction — a string that identifies what action the user is performing (e.g., login, submit, homepage). This must match the action configured on the target website.

How It Works

The workflow has the same three-node structure as v2:

Webhook — Receives POST requests at /solve-recaptcha-v3
CapSolver reCAPTCHA v3 — Solves with operation set to reCAPTCHA v3
Respond to Webhook — Returns the full CapSolver response as JSON

Node Configuration

1. Webhook Node

Setting	Value
HTTP Method	`POST`
Path	`solve-recaptcha-v3`
Response Mode	`Response Node`

2. CapSolver reCAPTCHA v3 Node

Parameter	Value	Description
Operation	`reCAPTCHA v3`	Must be explicitly set — different from v2
Type	`ReCaptchaV3TaskProxyLess`	Select in n8n based on the target site (see available types below)
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 — must match the site's action
Enterprise Payload	`{{ $json.body.enterprisePayload \|\| '' }}`	(Optional) For Enterprise reCAPTCHA
Is Session	`{{ $json.body.isSession \|\| false }}`	(Optional) Session-based solving
API Domain	`{{ $json.body.apiDomain \|\| '' }}`	(Optional) Custom API domain

Available types for reCAPTCHA v3 (select in n8n dashboard):

Type	When to use
`ReCaptchaV3TaskProxyLess`	Standard reCAPTCHA v3 — works for most sites (no proxy needed)
`ReCaptchaV3EnterpriseTask`	reCAPTCHA v3 Enterprise — requires a proxy (`ip:port:user:pass`)
`ReCaptchaV3EnterpriseTaskProxyLess`	reCAPTCHA v3 Enterprise without proxy

Important: The operation field must be set to reCAPTCHA v3 in the CapSolver node. If you leave it on the default (v2), the solving will fail or return an unusable token. Also, pageAction is required for v3 — unlike v2 where it's optional. Select the correct type directly in the n8n node — if you choose a type that requires a proxy, a proxy field will appear where you enter it in ip:port:user:pass format.

API Parameter Reference

All three API solver endpoints accept the same set of optional parameters through the CapSolver node. Here's a consolidated view:

Parameter	v2	v2 Invisible	v3	Description
`websiteURL`	Required	Required	Required	The URL of the page hosting the captcha
`websiteKey`	Required	Required	Required	The reCAPTCHA site key
`pageAction`	Optional	Optional	Required	The action name configured on the site (e.g., `login`, `submit`)
`enterprisePayload`	Optional	Optional	Optional	Additional payload for reCAPTCHA Enterprise
`isInvisible`	Optional	`true` (hardcoded)	—	Whether the captcha is invisible
`isSession`	Optional	Optional	Optional	Enable session-based solving
`apiDomain`	Optional	Optional	Optional	Custom API domain (e.g., `recaptcha.net`)

Tip: You can identify all of these parameters automatically using the CapSolver Browser Extension. The extension's CAPTCHA Detector tab shows exactly which parameters the target site requires.

Real-World Examples: 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

The following examples demonstrate this full cycle using Google's official reCAPTCHA demo sites.

Example 1: Solving & Submitting reCAPTCHA v2

Example: Google reCAPTCHA v2 Demo

Workflow Flow

Copy

Manual Trigger → CapSolver reCAPTCHA v2 → HTTP POST Request → IF (check success) → Edit Fields (extract data)

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:

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
Edit Fields — Extracts the data you need from the response. In a real scenario, this is where you'd parse the HTML using the HTML node to pull out specific elements (e.g., user data, product listings, form results) and map them to your output fields

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.

Example 2: Solving & Submitting reCAPTCHA v2 Invisible

Example: reCAPTCHA v2 Invisible Demo

reCAPTCHA v2 Invisible scraping workflow in n8n

Workflow Flow

Copy

Manual Trigger → CapSolver reCAPTCHA v2 Invisible → HTTP POST Request → IF (check "Success!") → Edit Fields (extract data)

How It Works

Manual Trigger — Starts the workflow. You can replace this with a Webhook, Schedule, or any other trigger to automate the process.
CapSolver reCAPTCHA v2 Invisible — Solves the invisible captcha:
- Website URL: https://recaptcha-demo.appspot.com/recaptcha-v2-invisible.php
- Website Key: 6LcmDCcUAAAAAL5QmnMvDFnfPTP4iCUYRk2MwC0-
- Is Invisible: true
HTTP POST Request — Submits the token along with the form's other fields:
- ex-a: foo (example form field)
- ex-b: bar (example form field)
- g-recaptcha-response: the solved token
IF Node — Checks if the response contains "Success!"
Edit Fields — Extracts the data from the response. After the site accepts your token, the HTML response contains the protected content — use the HTML node to parse specific elements or Edit Fields to map the data you need

Key concept: Real forms often have additional fields beyond just the captcha token. You need to include all required form fields in your HTTP Request — not just g-recaptcha-response. Inspect the form to find what fields are expected.

Example 3: Solving & Submitting reCAPTCHA v3

Example: reCAPTCHA v3 Demo — Request Scores

Workflow Flow

Copy

Manual Trigger → CapSolver reCAPTCHA v3 → HTTP GET Request (verify) → IF (check success) → Edit Fields (extract data)

How It Works

Manual Trigger — Starts the workflow. Swap this for a Webhook, Schedule, or any trigger that fits your use case.
CapSolver reCAPTCHA v3 — Solves the v3 captcha:
- Operation: reCAPTCHA v3 (must be explicitly selected)
- Website URL: https://recaptcha-demo.appspot.com/recaptcha-v3-request-scores.php
- Website Key: 6LdKlZEpAAAAAAOQjzC2v_d36tWxCl6dWsozdSy9
- Page Action: examples/v3scores
HTTP GET Request — Submits the token to the verification endpoint:
- URL: https://recaptcha-demo.appspot.com/recaptcha-v3-verify.php?action=examples/v3scores&token={{ $json.data.solution.gRecaptchaResponse }}
- The token is passed as a URL query parameter instead of a form field
IF Node — Checks if the JSON response has success: true
Edit Fields — Extracts the data from the JSON response. For v3, this includes the score, action, challenge_ts, and hostname — all useful fields to capture for your records or downstream processing

Key differences with v3:

The CapSolver node operation must be set to reCAPTCHA v3

You must provide the pageAction parameter (e.g., examples/v3scores)

The token is often submitted via URL parameters (GET) rather than form POST

The verification response is typically JSON with a success boolean and a score

Applying This Pattern to Any Website

These examples use demo sites, but the pattern works for any reCAPTCHA-protected website. To adapt it:

Identify the captcha parameters using the CapSolver extension (website URL, site key, type, pageAction)
Inspect the form submission — Use your browser's DevTools Network tab to see what request the form sends when submitted (URL, method, headers, body fields)
Replicate the request in n8n — Configure the HTTP Request node to match the form submission exactly, inserting the solved token in the g-recaptcha-response field
Add validation — Use an IF node to check the response and confirm the data was unlocked
Extract the data — Once the site accepts the token, parse the response to extract the data you need. Use the HTML node for HTML responses or Edit Fields for JSON responses

Note: These examples use Manual Trigger for simplicity, but you can replace it with any trigger node — Webhook (to build an API), Schedule (to run every hour), App Event (to react to Telegram messages), or any other. See Ways to Trigger Your Workflows for all options.

Ways to Trigger Your Workflows

The examples in this guide use Manual Trigger (for scraping workflows) and Webhook (for API workflows), but n8n offers many more ways to start a workflow. You can swap the trigger node to match your use case:

Trigger	Description	Best for
Trigger manually	Click "Execute workflow" in n8n	Testing and one-off runs
On a schedule	Runs every day, hour, or custom interval (cron)	Recurring scraping jobs (e.g., check a site every hour)
On webhook call	Runs on receiving an HTTP request	Building APIs that other services can call
On app event	Runs when something happens in Telegram, Notion, Airtable, etc.	Reacting to events (e.g., new Telegram message triggers a solve)
On form submission	Generates a web form in n8n and passes responses to the workflow	Letting users submit captcha parameters through a form
When executed by another workflow	Called by the Execute Workflow node from a different workflow	Modular architecture — keep your solver as a reusable sub-workflow
On chat message	Runs when a user sends a chat message (AI nodes)	Chatbot integrations that need to solve captchas on demand
Other ways	Workflow errors, file changes, etc.	Advanced automation triggers

For example, to run your scraping workflow every hour, simply replace the Manual Trigger with a Schedule Trigger node and set the interval to 1 hour. The rest of the workflow stays exactly the same.

Storing and Exporting Scraped Data

Once your workflow solves a captcha and retrieves data from the target website, you'll want to store or export that data. n8n provides built-in data transformation and output nodes for this.

Data Transformation

Before saving, you can transform the scraped data using n8n's built-in nodes:

Node	Description
Merge	Combine data from multiple sources (e.g., merge results from v2 and v3 scrapers)
Summarize	Sum, count, max, etc. across items
Convert to File	Convert JSON data to CSV, Excel, or other binary formats
Extract from File	Convert binary data to JSON
HTML	Parse and extract data from HTML responses
XML	Convert between JSON and XML
Rename Keys	Rename fields to match your desired output format
Sort	Reorder items before exporting

Output Destinations

After the IF node validates the response, you can add any of these nodes to save the data:

Destination	How
Google Sheets	Append rows to a spreadsheet — great for tracking results over time
Excel / CSV file	Use the Convert to File node to generate `.xlsx` or `.csv`, then save with the Write Binary File node or upload to Google Drive
Database (MySQL, PostgreSQL, MongoDB)	Insert directly into a database table for structured storage
Airtable / Notion	Send data to your project management tools
Google Drive / S3	Upload files to cloud storage
Telegram / Slack / Email	Send notifications with the scraped data
Local JSON file	Write results to a `.json` file on disk

Example: Adding Google Sheets output to the v2 scraping workflow

Copy

Manual Trigger → CapSolver v2 → HTTP POST → IF (check success) → Google Sheets (append row)

Simply add a Google Sheets node after the IF node's "true" output. Map the fields you want to save (e.g., status, token, timestamp) and each successful scrape automatically adds a row to your spreadsheet.

Tip: You can combine multiple outputs — for example, save to Google Sheets and send a Telegram notification at the same time by connecting both nodes to the IF node's "true" output.

Troubleshooting

"ERROR_KEY_DOES_NOT_EXIST" or Invalid API Key


Symptom	CapSolver node fails with an API key error
Cause	Your API key is incorrect or not configured
Fix	Double-check your API key in Settings → Credentials.

"ERROR_ZERO_BALANCE"


Symptom	Task creation fails with a balance error
Cause	Your CapSolver account has no credits
Fix	Top up your balance at the CapSolver Dashboard

Wrong or Expired Token


Symptom	The returned `gRecaptchaResponse` token is rejected by the target website
Cause	reCAPTCHA tokens expire after ~120 seconds
Fix	Use the token immediately after receiving it.

Token Not Accepted by the Website


Symptom	CapSolver returns a token successfully, but the target website still rejects it
Cause	Some websites have additional anti-bot protections beyond reCAPTCHA, or require specific parameters (Enterprise, cookies, headers) that weren't included
Fix	Double-check that you're submitting the token exactly as the site expects (correct field name, method, and endpoint). Make sure all required parameters are set (check with the CapSolver extension). If the token is still not accepted, contact the CapSolver support team for assistance — they can help diagnose site-specific issues

reCAPTCHA Enterprise Not Solving


Symptom	Standard solving doesn't work on some sites
Cause	The site uses reCAPTCHA Enterprise, which requires additional parameters
Fix	Use the CapSolver extension to check if `isEnterprise` is `true`. If so, include the `enterprisePayload` parameter in your request

Timeout or Slow Response


Symptom	The webhook takes too long or times out
Cause	Captcha solving can take 10-30 seconds depending on complexity and load
Fix	Increase the webhook timeout in n8n settings. Consider adding retry logic for production use cases

Best Practices

Use tokens immediately — reCAPTCHA tokens expire quickly (~120 seconds). Send the token to the target website as soon as you receive it from your solver API.
Verify parameters with the extension — Always use the CapSolver browser extension to confirm the correct websiteKey, captcha type, and additional parameters before configuring your workflow.
Keep your API key secure — Never expose your CapSolver API key in client-side code. These n8n workflows keep your key server-side, which is the recommended approach.
Monitor your balance — Set up balance alerts in the CapSolver dashboard to avoid unexpected workflow failures due to insufficient credits.
Add error handling — For production workflows, add an IF node after the CapSolver node to check for errors and handle them gracefully (e.g., retry, notify, or log the failure).

Conclusion

You've learned how to build reCAPTCHA-solving APIs and complete 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
Real-world scraping examples showing how to submit solved tokens to target websites and verify the results
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. The scraping examples show you exactly how to do this for each reCAPTCHA type.

Frequently Asked Questions

What captcha types does CapSolver support in n8n?

CapSolver's n8n node supports reCAPTCHA v2, reCAPTCHA v2 Invisible, reCAPTCHA v3, and more. Check the n8n CapSolver integration page for the full list.

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.

Can I solve reCAPTCHA Enterprise with these workflows?

Yes. Use the CapSolver extension to detect if a site uses Enterprise reCAPTCHA. If it does, include the enterprisePayload parameter in your API request to the v2 solver workflow.
