Recently, we've updated the CAPTCHA security measure on our Hosted payment pages (HPPs) to a newer version. The new CAPTCHA does not have a challenge but instead tries to determine if the user is a human based on their interaction with the page. It's based on a scoring system to detect non-human activity to block fraudulent activity. Some users are experiencing CAPTCHA errors at the time of sale. This is indicating those users are failing that CAPTCHA. If you are encountering issues, we would advise users to manually enter their data and not allow web browsers to auto-fill data when making the payment. If you've already failed a CAPTCHA please clear your cache and cookies and try again with the above method. Or try using a different web browser to try again while being careful to not allow auto-fill. Please also be careful to not include repeating words or words like 'test' or 'testing'.
