Hi @randon_noob
Sorry for the delay, just saw this. That's an extra I started work on however it's only in very early stages. It was the beginning of a proof-of-concept for a job that never eventuated. Unfortunately not even close to being used in production.
From memory the only things built were:
- tickets integration into a MODX CMP where real-time tickets were pulled through from WHMCS via a custom API getlist processor.
- on the web context I think I had a snippet that would handle domain searches and display the results pulled from WHMCS.
Honestly though, WHMCS is very usable without MODX integration. You can install WHMCS in a subdomain or a subfolder and just send people through to your WHMCS front-end from your MODX site for any logged-in interactions. You can adjust the CSS of the WHMCS pages to match the style of your MODX site. For example, if you have a "login" button or "buy now" link on your MODX site, just link it through to the appropriate page on the WHMCS site. Easy!
In terms of managing it, just use the separate WHMCS admin section.
Hope that helps
