From LinkedIn Lead Generation -> FORM -> CRM

We have an integration between Eloqua and our CRM where when a form is submitted, the contact data is posted to the CRM and a lead is generated.

However, we also have events where the registrations are in LinkedIn and don't use Eloqua forms at all. Using the LinkedIn Campaign Manager app in Eloqua I can get the contacts into an Eloqua campaign, then I get stuck. Can anyone point me to how I can push those contacts through the 'post to server' processing step of a form?

Many thanks, Vicky
