Hello. I am adding a TrustedForm code in my web form so I can authenticate the IP and referring url of lead or opt-in source.
I need to add xxTrustedFormCertUrl that has the certificate url. This will allow me to validate the referring url of every lead. Using this to ensure referring url source as accurate and not declared in the form (and can be manipulated).

Hope you can help me make this work as I need to put my opt-in form on multiple sites.
