Support for the "isEnterprise" parameter for reCAPTCHA v3 has been added in the CapMonster Cloud API 

isEnterprise — fast and convenient solution

The CapMonster Cloud API now supports the isEnterprise parameter for reCAPTCHA v3 tasks (RecaptchaV3TaskProxyless). This parameter allows solving reCAPTCHA v3 Enterprise using the same task type without creating a separate configuration (a separate task RecaptchaV3EnterpriseTask is still available as before).

If the Enterprise version is used on the site, a standard request for reCAPTCHA v3 may not work correctly or may return an error. By specifying isEnterprise: true, you inform the API to apply logic specifically adapted for the Enterprise variant. This ensures proper captcha handling and improves the stability of obtaining a valid token.

Thus, the parameter simplifies integration, makes configuration more universal, and allows using the same task type for both the standard and Enterprise versions of reCAPTCHA v3.
