When a user signs up to my website, I create a HTTP request to add the user’s name & email to my Mautic Contacts.  
  
  
  
I want to do 2 things:

1. Merge the (previously Anonymous) user with the new Contact, so all activities/points of the Anonymous user are now the Contact’s.  
2. Track the website user as the Contact  
  
  
  
Every user on my website has a User ID. This ID is saved in a custom field in Mautic (Unique Identifier). Is it possible to use this ID to track the proper user?  
  
Right now I’m doing

Code:

mt('send', 'pageview', {email: 'user email', fingerprint:'md5 hash of user id'});

, but the tracked user is still Anonymous, even though the email defined in mt('send') belongs to a Contact.
