Hi. I have a curly question which may be easy to answer. we integrated IS and Amember 3, so far so-so. After a free new member signs up on our own hosted webform, IS sends an http post to Amember and creates a new record. Works a treat. Amember then creates the thank you page with the upsell - we host the page so we can control the php based taguchi testing on it. If they buy the upsell they click a link which should be in the format ?inf_contact_key so tags can be applied before the next page is shown. Conversely if they pass on the offer they click another ?inf_contact_key link, tags are applied and then they are on the next page. My question is how to pass the values back from Amember to the thanks page, and construct those ?inf_contact_key links ... Any guidelines would be appreciated. Thanks from Rick
