How to connect WHMCS Integrator with Appointments+

I installed WHMCS Integration and appointments+ on my website. I don't sell hosting but services for clients and I use the WHMCS to bill my customers. How can I get both of them to work together so that when I create my Account section for WHMCS Integrator it will also pull the data for the appointments+ and display on the same page. I see that the WHMCS Integrator only creates a user inside WHMCS and not inside of wordpress.
