Does anyone know if it’s possible to store an input field on our website (shopify) into the user’s Klaviyo profile as a custom field?
For example say on our shopify product page (not a klaviyo sign up form) there’s a input field called ‘foo’ where the user enters free form text. We want to take the value of the input field ‘foo’ and save it as a custom property in the user’s Klaviyo profile with every key press as the user is inputting values into the foo input field (ideally with a straight javascript call to Klaviyo on the product page without the use of any custom built apps).
