We have a link in our footer that goes to a page with an embedded Formstack form. I understand how to pre-populate the form by editing the URL, but I'm unsure how to get the respective fields from Magento.
If the user is logged in to Magento, I would like to use their First Name, Last Name, and email address to pre-populate the respective fields in the formstack form.
In the end I need something like this
?firstname=John&lastname=Doe&[email protected]
with the actual customer data. How can I retrieve this data within a CMS page?
