title: How would I reference a user account on bigcommerce so that they don't need 2 logins?
body: <p>I have shop.domain.com, and in www.domain.com i have some social stuff going on with a blog, etc. I want users to be able to post comments on the blog, and use the social features without having to maintain 2 separate logins. </p>
  
  <p>Can/should I use the webhook to capture their info when they register and send it my way?</p>
