The Rezgo API automatically monitors usage and will notify you should your API show unusual activity. If you receive an API warning message, check your web stats or analytics to see if you can find any unusual spikes in traffic. If you are using a content delivery network (CDN) like CloudFlare or you do daily PCI scans from a service like McAfee, make sure to exclude your Rezgo pages. If you continue to receive API warnings from Rezgo, this may be an indication that something is triggering excessive usage on your site. If you do not rectify the problem, your API usage may be restricted.
