In our shopify shop we are developing some functionality related to customer account. Related data is stored on third party server. We are receiving that data with AJAX requests. The only way we are verifying customer now is his email. So for specific email we are giving specific data. As you understand, it is not very secure, since anyone who nows email and urls might retrieve that data. So I would like to get assistance of this beautiful community on how we can authorize requests to 3rd party servers from shopify account.
