Hello, I'm very new to Drupal and need some guidance on how to post the Registration data to a 3rd party tool, in this case - Lyris.

Lyris provides an opt-in form to quickly create a new record in their mailing list.

I've activated the Profile Module to add some additional fields to the User Object during Registration.

When a user successfully registers on my site, I'd like to take some of the fields and submit them to Lyris using the Lyris opt-in form.

I've done this with php and javascript on an older site, but I'm struggling with how to achieve the same results within the Drupal framework. I would think that I could add the Lyris opt-in form as a hidden, second form in my User Registration Template. After validation, I could call a javascript function which assigns the Drupal Registration values to my hidden Lyris form fields, and then submits the form.

Any thoughts on how to achieve the desired effect? (Creation of a new Drupal user and insertion of a new Lyris record with a single click)

Thanks, and apologies if this question has been asked...I've searched for many hours looking for a solution.
