When trying to load Zendesk or place an API request why do I see a security check request with a reCAPTCHA challenge?
(Example for web)
To ensure a high bar of security for everyone using Zendesk, we use a DDoS protection and abuse prevention system. Due to this, there might be times when you try to load a Zendesk page or place an API request that you are prompted to complete a CAPTCHA challenge in order to proceed with the process. This will prevent bots from accessing the site, but real humans can complete the CAPTCHA to proceed.
If you continue to see the CAPTCHA challenge, please consider checking your IP address reputation in an IP Address Inspector. In case your IP appears in bad host lists the best course of action is for you to contact your service provider to ask to assign you a new reputable IP.
