Recently, my IPN calls have been failing and instead being redirected to a "Security Challenge" page with a "I am not a robot" reCaptcha control on.
Since the IPN code is automated, we are unable to clear the reCaptcha.
Has anyone else experienced this and found out how to bypass it? My IPN code seems fine and works 50% of the time. If I capture the IPN request and try and verify it again it works.
