WHMCS Client Area for WordPress by WHMpress 4.1-revision-9
WCAP will bring WHMCS Client Area functionality to WordPress through WHMCS API, this is the part that users will access after logging into to their WHMCS. It also offers ordering and cart. It does not iframe existing WHMCS pages into WordPress, but it uses API to transfer only data, and then re-make all pages within WordPress. This approach gives a real authentic WP experience.
