Under the captcha itself, a field will appear where you need to enter the token. This can be done with the action Setting the value .

After successfully recognition the captcha, the response containing the token will be placed in the variable to be sent to the server. It must be substituted into the request, most often it is the g-recaptcha-response argument.

• In the source code of the DOM page

• In traffic window on page load

The token is sent in the browser by substituting it. The tab method is only suitable when the request to Google will occur after the form has been submitted

Consider the example of a site https://lessons.zennolab.com/captchas/recaptcha/v3.php?level=beta

During the loading of the site, there was no request for the captcha, which means that the method of recognition in the tab suits us.

We receive the token. Next, using the C # C# snippet, we send it to the site:

var sitekey =  project.Variables["имя_переменной_sitekey"].Value;
var newToken = project.Variables["имя_переменной_token"].Value;
var replaceRegex = @"(?<=\[""rresp"","")[^""]+";
instance.ChangeResponse("https://www.google.com/recaptcha/api2/reload\\?k="+sitekey,
  new List<string> {replaceRegex}, new List<string> {newToken}, false);

The use of SiteKey in the snippet is optional. But keep in mind that without using SiteKey, requests from all captchas, including ReCaptcha2, will be intercepted.

If this is not a problem, you can use this version of the snippet:

var newToken = project.Variables["имя_переменной_token"].Value;
var replaceRegex = @"(?<=\[""rresp"","")[^""]+";
instance.ChangeResponse("https://www.google.com/recaptcha/api2/reload\\?k=",
  new List<string> {replaceRegex}, new List<string> {newToken}, false);

We send the form on the site.

In the traffic window, you can make sure that the substitution of the token for the required one has occurred

If in the traffic window we see that the request is being executed along with the loading of the site page, then the procedure differs from recognition in the Tab

First, we set up the cube for solving the captcha and get the token

We receive the token. Next, using the C # C# snippet, we send it to the site:

var sitekey =  project.Variables["имя_переменной_sitekey"].Value;
var newToken = project.Variables["имя_переменной_token"].Value;
var replaceRegex = @"(?<=\[""rresp"","")[^""]+";
instance.ChangeResponse("https://www.google.com/recaptcha/api2/reload\\?k="+sitekey,
  new List<string> {replaceRegex}, new List<string> {newToken}, false);

The use of SiteKey in the snippet is optional. But keep in mind that without using SiteKey, requests from all captchas, including ReCaptcha2, will be intercepted.

If this is not a problem, you can use this version of the snippet:

var newToken = project.Variables["имя_переменной_token"].Value;
var replaceRegex = @"(?<=\[""rresp"","")[^""]+";
instance.ChangeResponse("https://www.google.com/recaptcha/api2/reload\\?k=",
  new List<string> {replaceRegex}, new List<string> {newToken}, false);

Only after that we load the page with ReCaptcha v3 and perform the necessary actions
