Connecting API to WordPress Project Management plugin - CQPIM WordPress Project Management Plugin

Hi, I wanted to ask if it would be possible to link the Free Agent API to
this WordPress plugin: CQPIM WordPress Project Management Plugin?

We are looking at using this Project Management WordPress plugin as it
offers a great deal of functionality for managing projects and clients. The
Plugin has the facility to create and send Invoices but I want to find a
way of linking this plugin to Free Agent to allow seamless communication
from project to invoice to Free Agent.

I look forward to hearing if there are any possibilities.

All the Best.
