I’m having a hard time getting forms to be prefilled after sending a double optin email. I’ve got a fresh Mautic 6.0.3 installation in which I’m trying to get the double optin mail working. **Main goal** When a client receives his double optin email I want to have a form embedded asking to give us more information. This information needs to be stored within his own profile (not a new record). - I’ve created an email - I’ve created an (optin) form - When a record is created a custom field ‘uid’ is automatically filled with an unique ID - I’ve created a campaign - The campaign sents the email - The email has a link to a page on my website (thankyou.php?uid={contactfield=uid}) - The page on my website (thankyou.php) has the mtc.js (tracking) script included - The page on my website embeds the form with the given javascript code So far everything works, but: the form will not prefill the clients information. When the form is submitted a new record is being created and I would like that the clients record gets updated with the values given. **What to do?** I cannot get the form to be prefilled when the page is visited after clicking on a link in the email. Can anybody assist and help me out?
