Flow Steps

1. Access to the workspace is granted by following the instructions outlined in the "How to Set Up" section.

2. The 'Inject' node is used to initialize the flow.

3. To begin, create a variable named 'website_url' to store your specified website URL. You will utilize this variable when opening the website using the 'Open Link' node.

msg.website_url = "https://www.google.com/recaptcha/api2/demo"; //The website_url variable use to aceess website.
return msg; 

4. You should utilize the 'Open Browser' node to open your preferred web browser. Select the desired browser type from the 'Browser' options.

5. To open a specified URL that you've created under the 'Function' node, you should use the 'Open Link' node and populate the input options of 'URL' type with the 'msg' object.

6. To create a session using the 'Cap Monster' package and the 'Create Session' node, you need to acquire a Cap Monster API Key. You can generate this API Key by visiting the website https://capmonster.cloud/en/ .

7. You can access the 'API KEY' from the flows by initially creating a 'Vault' and then adding an 'API KEY' item.

• Click on 'Vaults'.

• Set your workspace password and then click on 'Open'.

• Create a 'Vault' and save the 'Vault Secret Key'.

• Create Item and set your ‘API KEY’ this item.

8. To fill in the 'Website URL' and 'Website Key' fields in the 'Solve Recaptcha v2' Node, follow these steps:

Go to the website where you want to solve the reCAPTCHA.

Open your web browser's developer tools by pressing 'F12' or by right-clicking on the webpage and selecting "Inspect" or "Inspect Element."

In the developer tools panel that opens, switch to the "Elements" tab.

Use the search function by pressing 'Ctrl + F' (or 'Cmd + F' on Mac) to open the search bar.

In the search bar, type 'sitekey' and press 'Enter' to search for this keyword within the webpage's HTML code.

Locate the 'sitekey' value in the HTML code; it typically appears as an attribute within a reCAPTCHA-related element, like this: data-sitekey="your-sitekey-value-here."

Copy the 'sitekey' contents, which represent your 'Website Key,' and paste it into the appropriate field in the 'Solve Recaptcha v2' Node.

By following these steps, you can extract the 'Website Key' from the website's HTML source code and use it in the 'Solve Recaptcha v2' Node.

You should verify whether the captcha-solving process has completed successfully or is still in progress by using the 'Get Result' node from the 'Cap Monster' package.

Example of a response from the 'Get Result' node:

9. If the value of the status is 'processing' or if there is a different error, proceed with the 'Sleep' node, wait until the specified time has elapsed, and then proceed to the 'Get Result' node to check the response.

10. Check the response of the 'Get Result' node by using the 'Switch Node.' If the status value in the response is 'Processing,' you should recheck. If the response contains a solution, it indicates that the captcha has been successfully solved.

11. If the response has the value 'solution,' you should set the 'gRecaptchaResponse' value to 'textarea.value' using the 'Run Script' node.

var textarea = document.querySelector("#g-recaptcha-response");
textarea.value = msg.response.solution.gRecaptchaResponse;

12. Next, click the 'Submit' button and then use the 'Close Browser' node to close the browser.

13. Stop the flow with the 'Stop' node.
