Hello Google Support Team,
I am encountering the following error while implementing Firebase reCAPTCHA with the Identity Toolkit API for Phone Authentication:
{
"error": {
"code": 400,
"message": "CAPTCHA_CHECK_FAILED : Recaptcha verification failed - SITE_MISMATCH",
"errors": [
{
"message": "CAPTCHA_CHECK_FAILED : Recaptcha verification failed - SITE_MISMATCH",
"domain": "global",
"reason": "invalid"
}
]
}
}
I have already tried using the sendVerificationCode method from the Identity Toolkit API on both the server and client sides, but I continue to encounter the same issue.
Could you please assist me in understanding the cause of the SITE_MISMATCH error and how to resolve it? Any guidance on what needs to be configured to avoid this error would be greatly appreciated.
Thank you in advance for your help!
Best regards,
Muhammad Nadeem
