Then we follow the link and get to the registration form with partially filled fields.  
For example  
“phone” ,  
“custom\_questions”  
Tell me how you can either skip this form or how to autocomplete fully passed fields.

```auto

Hey @vvarakin,

In the UI, can you make sure that these options are checked off in your webinar’s registration settings? This will need to be verified in the UI. To do so, go to the webinar, scroll down to registration settings, click edit, and then go to the “questions” column to check off the desired options.

Let me know if this helps,  
Will
