Joomla / Community Builder / onAfterUserRegistration call web service

I have Joomla running with Community Builder. When a member is created(I think the CB onAfterUserRegistration event) using data from the community builder registration form I would like to: o) Call a create business webservice o) Save the business id in a CB field o) Call a create user webservice o) Save the user id in the CB field o) If there are any exceptions send me an email with all the details. Pretty simple I think for someone familiar with CB.
