# IP Whitelisting

IP Whitelisting is an added security measure, which allows clients to specify which IPs they want to permit to make API requests of their data. Should another IP make a request, the request will not be successful.

To whitelist an IP, simply select `Update` on your active token and then either add the permissioned IP addresses to the list of valid IPs. You can add your current IP using the `Add my IP` option. Users are not limited to how many IPs they can whitelist. Alternatively, IPs can be added when the token is first created.<br>

When finished, select `Save`. \

The list of a token's permitted IP addresses can be edited while the token remains active.&#x20;
