Hi all!

I’ve found that HubSpot forms are capable of capturing things like UTM parameters and GCLID via hidden fields; with all the changes with Apple iOS and how it’s effecting Facebook and Google ads, has anyone been able to capture other needed fields (such as IP address, useragent, FBCLID, FBPLID, etc.) in order to successfully set-up both Facebook’s Conversion API and Google Measurements?

Thanks in advance!

Hi @LauraHW,

I wanted to tag a few subject matter experts here: [@Mike\_Eastwood](https://community.hubspot.com/t5/user/viewprofilepage/user-id/9259), @NicoleSengers, @StefaniUAT, [@Alejandro\_](https://community.hubspot.com/t5/user/viewprofilepage/user-id/115716) do you have any tips regarding hidden fields in forms you could share?

Thank you!

Hello @LauraHW,

There are 12 default properties provided by HubSpot to identify the source of contact deeply. In this link, you find the explanation for all the default properties by HubSpot:

> **[HubSpot's default contact properties](https://knowledge.hubspot.com/properties/hubspots-default-contact-properties)**
>
> Learn more about the definitions of HubSpot's default contact properties.

And these 12 properties are automatically captured by HubSpot and your UTM’s are captured in “Original source drill-down 1” & “Original source drill-down 2” properties.

And yes you can create your UTM’s in HubSpot itself, refer to this link - [UTM Codes: How to Create UTM Tracking URLs on Google Analytics](https://blog.hubspot.com/marketing/what-are-utm-tracking-codes-ht)

Now coming to your query you asked for a hidden field, yes there is a feature in HubSpot but the fields you asked for are automatically filled by HubSpot, so your question looks a little contradictory to me. 🤔

Regards,

Hi Himanshu, that link was helpful, thanks!

It’s still, however, hasn’t answered all of my questions - I see specifically that HubSpot now doesn’t capture IP address; and I still need to capture the other parameters not mentioned in the article (useragent, fbp) too.

Really, the long game is that with the changes with iOS, I’m looking for a CRM that can capture what’s needed to sucessfully set up Facebook Conversion API and Google Measurement Protocol. I’d love to hear from anyone who has been able to do it with Hubspot!

Thanks again!
