We know there are many pop-up apps but most of them don’t support multi-languages.
So, we plan to develop the pop-up by ourselves. But we don’t know how to send the email data to Shopify > Customers, when customers enter their email address and click the button “Submit”
Does anyone know how to send the data? Or does Shopify provide the API to send the data?
Note that front end liquid theme forms cannot modify existing customers properties such as tags, where a customer is not the same thing as a contact. To do something like requires an app to consume the form submission and communicate with the backend.
