To secure your integration, we strongly recommend that you use both of these options. This will protect your integration code from fraudulent and unauthorized uses.
This setting allows you to specify the daily maximum number of lookups that can be performed by an individual user (identified by an IP address). This will help limit unauthorized uses of your validation services.
To set the limit, click Enable to set look up limit and enter a numeric value.
Once an individual user hits the limit, they will get the ‘Too many validations’ error and will be disabled from making validations for the rest of the day.
We strongly recommend that you specify at least one domain or sub-domain for each integration. This ensures that the integration code we provide to you is not accessible to any other websites.
To specify the permitted domain(s), simply enter the permitted URL(s). For example, www.mywebsite.com.
