Form Source Attribution

I have a number of sign-up/newsletter forms in various locations all feeding a single CRM base. I’d like to create attribution that allows me to see in the base where the contact originally came from (e.g. website, LinkedIn, Partner site).

I’d like to do this in a way that means the person filling out the form doesn’t see the attribution being applied. (So I can’t use ‘/?prefill_’ ).

Thank you in advance!

Hey Graham. I don’t know if there is an elegant answer, but you could always disguise the attribution with a non-sense field name and non-sense field value, which you translate later.

Let us know if you figure out a clever way!
