Not working for me...

So I followed all installation instructions and so far I don't understand if it's working or not. Loged in as Admin in my WHMCS, I have activated access to WHMCS Provisioning, and have added the remote site ID, however, nothing has changed in the admin area nor the wp area, nor the clientarea. . . what am I not doing or still need to do and can you help streamline this?
