Identify pageAction, reCaptcha Enterprise, anchor, reload, the type of the reCaptcha, data-s parameter and more!

Understanding Additional Parameters

reCaptcha v2:

  • reCaptcha versions: These can vary and include:

    • reCaptcha v2 Normal: The standard version where users solve a puzzle to verify they're not a bot.
    • reCaptcha v2 Enterprise: An advanced, paid version with more features and customization options, designed for businesses requiring higher security.
    • reCaptcha v2 Invisible: A version that operates in the background, typically requiring no user interaction. It uses a risk analysis engine to differentiate between users and bots.

  • pageAction: This is a parameter found in some site anchor endpoints. It represents the 'action' value and is used in reCaptcha v3 for risk analysis.

  • enterprise payload: This refers to the 's-data' in reCaptcha, which is a set of data sent to reCaptcha Enterprise for analysis. The exact contents depend on the specific requirements of reCaptcha Enterprise.

  • Anchor: This is additional data obtained from the Capsolver extension. In the context of reCaptcha, it could refer to the part of the page where the reCaptcha widget is anchored.

  • Reload: This is also additional data obtained from the Capsolver extension. It could refer to the action of reloading the reCaptcha widget, for instance, if the user wants a new challenge.

  • ApiDomain: This is the domain address from which to load reCAPTCHA Enterprise. Examples include 'http://www.google.com/' and 'http://www.recaptcha.net/'. This parameter should only be used if its purpose is understood. Don't use a parameter if you don't know why it's needed.

These parameters are not always present and their presence depends on the site key.
