I’m prepopulatimg user information with custom url.

I’m prepopulatimg user information with custom url. Works great.
What I’m trying to do is add a couple invisible ID in background so when they finish form, the returning websocket will include those ID and so I can match response to a specific row ID in my database .
I’ve done this by having a page at the end with these variables I need returned and hiding that page. This is super clunky and prone to errors/typos…. Is there a better way? If I upload say 10 variables in URL, it would be so helpful to get ALL the original url parameters back regardless if they have been used.
Hope that is clear.

Hi James,

Thanks for reaching out to Jotform Support. If you can share the form link and a sample of your prepopulated URL, that we'll give us a better idea of what's happening and how to help. If you're trying to get the URL link into your form, you may try looking into the Get Form Page URL widget.

After we hear back from you, we’ll have a better idea of what’s going on and how to help.
