Eloqua External Form Prepopulation

Hello everyone,

for the past few days I'm having a battle with prepopulating an Eloqua form in an external website. Documentation I followed is simple and user friendly, but somehow the form is still not being prepopulated.

My website is whitelisted in Eloqua and tracking test is flawless.

These were my steps in creating an external form prepopulation:

1. Embedding a form in an External Website  (https://docs.oracle.com/cloud/latest/marketingcs_gs/OMCAA/Help/Forms/Tasks/EmbeddingFormInWebPage.htm)

2. Creating an Email with a link to my website

3. Creating a Web Data Lookup

         

    Also, I have tried with the Restricted checkbox off, but it still wasn't prepopulated.
