I have a custom HTML email that has a "View in browser" option. When that link is clicked they are taken to a Visualforce page hosted on a force.com site. I'm able to pass the contact.id and the contact.email parameters to that site URL, but then on the visualforce page there is a link to click to "Unsubscribe" to our emails and that link is associated with a flow on a different force.com site.
I need to pass the Contact.Id and Contact.Email that is showing up in the initial force.com site URL to the Unsubscribe URL.
I'm not sure how to do that. I'm thinking an Apex Class, but wasn't exactly sure....
Any help would be appreciated!
