Create a new form in Eloqua. Include any fields that you will use in Lead Liaison. You will need your form HTML, which includes your Form name, and Site ID to generate your endpoint. You can find your form HTML by opening the form, clicking the gear in the top-right, and selcting View Form HTML.
The Eloqua Endpoint URL usually looks like this: https://s*SITE ID*.t.eloqua.com/e/f2?elqformname=*FORM NAME*&elqSiteID=*SITE ID*
Next, create your event in Lead Liaison. Make sure to map custom fields in your Event form to system fields in Lead Liaison. Now you should have an identical form in Lead Liaison to your form in Eloqua.
