Sold License Verifier
Purpose
Sold License Verifier gives WHMCS admins a safe way to let users check whether a software licence is valid for a domain.
The standard WHMCS Software Licensing setup is powerful, but public verification can be too weak if it only checks a domain. This addon checks the actual licence key together with the authorised domain, service status and licensing status, so the result is much harder to guess or abuse.
It is for WHMCS admins who sell software licences through the WHMCS Software Licensing module and want a simple, read-only public licence checker.

This addon has an admin area and a client-area public checker page. The public page is designed to work inside the active WHMCS client-area theme. The optional menu item uses the WHMCS Primary Navbar. Some custom or heavily changed WHMCS themes may need a manual navigation item instead.
Requirements
Template support:
No template edits are required for the public checker page itself. The page uses the active WHMCS client-area theme. If the automatic Primary Navbar menu item does not appear in a custom theme, add a manual navigation link to the checker page.

PHP version:
7.4, 8.1, 8.2, 8.3 or 8.4

External access:
The addon checks local WHMCS Software Licensing data for licence verification. Normal outbound access may be required for the addon’s own WHMCS-addons.eu licence validation.
