Config or tweak my website operation/setting

I'm currently are using a joomla CMS, CB(Community Builder) & Idevaffiliate. This project requires you to write PHP code and/or cofigured my CB in order to POST data from obtained during registration in my Joomla website to autocreate & autologin user in Idevaffiliate. I'm looking for those familiar with CB & Joomla. I have Professional Membership from CB, that means you have the access to all plugins necessary to complete this task. Process flow: i) A user register through my CB registration page ii) Once the user is registered & payment has been performed, I want their registration data to be sent to my Idev to autocreate Idev account based on their subscription level (same username, password and few other additional predefined fields that compliment to Idev fields) ii) Create A Centralized Auto-Login Function - i want you to point me or config my Joomla to auto-log customers into their affiliate accounts by creating or adding a PHP session provided by Idevaffiliate I want you to solve problem in the 2nd & 3rd process flow. I want the user be able to auto login to my Idev affiliate website after login through my main website
