API Key Security
Your arpReach API allows you to control and access numerous functions within arpReach. To prevent abuse by third parties we strongly recommend you restrict access to your API keys using the facilities outlined here.
When creating an API key you have the optional ability to restrict the usage access of each API key to one or more specific IP addresses. When this facility is enabled that key and the API functions may only be used from the IP addresses specified.
You can (and should) install and use an SSL certificate with your domain name to further improve the security of your API keys.
