Hello,
I have a multi-step signup form, the first form is not from Klaviyo but it sends post data containing a field “first_name” to the page that generates the Klaviyo popup to subscribe to SMS.
I would like to nor have to ask the customer for their first name again and have it saved in Klaviyo. I know there is the possibility to use hidden fields but it isn’t exactly clear how to get and store the “first_name” field from the POST data?
Hope that makes sense!
