I run the analytics account for our company. One of our subsidiaries has their own analytics account for which I have admin access.

User "Anne" clicks on a link on Site A and is taken to a dynamic form on Site B. (The form is ASP.net and has a ".aspx" extension).

Anne fills out the form, presses "Submit", the page refreshes (but the URL stays the same!) and they are given a "Reference ID". (They are then called via phone but that is beyond the scope of this question). People who receive the "Reference ID" are considered converted.

There are many others links to site B aside from Site A.

Site A and Site B are different Analytics accounts.

I have already modified the link on Site A with all the "utm=medium" stuff.

I can ask the owners of Site B to make some minor code modifications.

Both sites use the old version of the tracking code.

Question:
I want to be able to retrieve a list of the "Reference ID"s that resulted from people who got to the page from site A.
