A: SharpAPI is, well, an API—complete with open data formats, documentation, and a wide range of SDK libraries. You can connect it to anything you want, but as an API, it requires some engagement from a developer to integrate SharpAPI's workflows into an existing app.

As far as I understand, FluentCMR is a WordPress plugin, and WHMCS also runs on the LAMP stack. You can integrate SharpAPI into both via our PHP Client SDK: https://github.com/sharpapi/sharpapi-php-client
