πŸ“‹ Frequently Asked Questions

How to Distinguish Between ReCaptcha v2 and v3?

Unlike other platforms, we only differentiate between regular and enterprise versions:

v3 Characteristics:

  • Ends at the reload interface
  • size parameter is typically invisible
  • Requires action parameter
  • Finding method: Open F12, search for grecaptcha.execute, find the action value in the function parameter object

v2 Characteristics:

  • After the reload interface, still needs to request the userverify interface
  • size is usually normal
  • No action parameter needed

How to Differentiate Between Regular and Enterprise Versions?

  • Regular Version: anchor interface route is /recaptcha/api2/anchor
  • Enterprise Version: anchor interface route is /recaptcha/enterprise/anchor

Why Can't Enterprise Versions with s Values (like Steam) Use the Token?

This is related to proxy quality. Recommendations:

  1. Try using your local IP first
  2. Switch to high-quality proxies
  3. If still unusable, contact customer service
