WHMCS API IP Access Restriction

WHMCS, short for Web Host Manager Complete Solution offers an API that allows us to integrate and interact with WHMCS services programmatically.

In fact, we can improve security with WHMCS as it restricts access to the API based on IP addresses. In other words, we can specify which IP addresses or IP ranges are allowed to make API requests to our WHMCS installation.

Let’s take a look at how to set up IP access restrictions for the WHMCS API:

1. First, we have to open a web browser and navigate to the admin area of our WHMCS installation.
2. Then, head to Setup and click API Configuration.
3. Next, we have to go to the API Configuration page and locate the “API Access Control” section. Then, make sure the “Enable API IP Access Restriction” option is enabled.
4. Now, we have to enter the IP addresses allowed to access the WHMCS API in the Allowed IP Addresses field.

   Additionally, we can enter different IP addresses by separating them with a comma. We can also enter IP ranges.
5. Finally, it is time to click Save Changes for the changes to come into effect.

At the end of the day, we can ensure that only authorized systems with the specified IP addresses or ranges can access the WHMCS API. This goes a long way in protecting the WHMCS installation from unauthorized API access attempts.
