To prevent denial of service attacks and server instability our web servers will block any further requests after receiving a large number of requests from a single location by returning a HTTP 403 Error. Furthermore any outstanding jobs will be deleted. This block will then be removed shortly afterwards. To prevent this from occurring try to reduce the rate of requests that are sent to the GrabzIt service.
This error occurs when more than requests than allowed for your package are made from a single IP address or Application Key to the GrabzIt service within a minute. Try to use the
Save method rather than the
SaveTo method to create screenshots as this is more efficient in terms of the number of requests made.
Another solution is to upgrade your account. Free packages are limited to 60 requests per minute. While the Entry, Professional and any Custom packages are limited to 120 requests per minute. The Business and Enterprise packages have a rate limit of 150 and 180 requests per minute respectively.
