Other Versions: reCaptcha V2 Invisible, reCaptcha V3, and reCaptcha V3 Enterprise 🤩

For these versions, the most effective method for identification involves using Charles Proxy. We'll explain what to check both with and without using Charles.

If you want to use Charles method, do the setup of Charles. If you don't want, just ignore this part.

Setting Up Charles 🛠

1. Download and install Charles Proxy.

2. Open Charles and navigate to Proxy > SSL Proxying to enable SSL Proxying.
   

3. Add the following hosts and ports in the Include panel:

   • Host: www.recaptcha.net, Port: 443
   • Host: google.com, Port: 443

Identifying reCaptcha V2 Invisible 🌟

Key Points:

• A challenge box will not always appear and is triggered only by suspicious activity.
  
• The captcha is loaded from the domain google.com or recaptcha.net.
• The "I'm not a robot" button is absent. Instead, an icon will be displayed in the corner.

Using Charles for Detection

1. If you have already Charles configured, open charles and go to the site with reCaptcha.
2. A request from google.com or recaptcha.net will appear, click and search for recaptcha. After you find, click the reload request.
   
   In Charles, inspect protobuf position 6 for a value labeled 'fi'. There must be a number 6 and also in this number the value fi to be v2 invisible. This is the most efficient way to confirm reCaptcha V2 Invisible.
   

Identifying reCaptcha V3 and V3 Enterprise 🍀

Key Points:

• The challenge box will not appear.
• The captcha is loaded from the domain google.com or recaptcha.net.
• An icon appears in the corner instead of the "I'm not a robot" button.

Using Charles for Detection

1. If you have already Charles configured, open charles and go to the site with reCaptcha.
2. A request from google.com or recaptcha.net will appear, click and search for recaptcha. After you find, click the reload request.
   
   Inspect protobuf position 8 for a value indicating the pageAction. There must be a number 8 and also with a string value that will be the pageAction that we need to submit to capsolver. This is the most efficient way to confirm it's reCaptcha V3 or V3 Enterprise.
