I would like to integrate a survey into the "after purchase" page in Shopify.
I have already created this survey as a sign-up form and added this script under --> Settings --> Checkout --> "After purchase" page under Additional scripts. Unfortunately, nothing is displayed to me during the test purchase.
The goal is to assign tags to customers based on this survey. Example: The customer buys a birthday present and 360 days later the customer receives an email (target: repeat buyer).
