I have an application that is an online shopping cart. You can see a sample of the application at https://1securecart.com/order.asp?userid=2051. The application is designed to be used by many users with a UserId. You can see that in the sample code. Here's an example of how it should work from another project of mine https://www.facebook.com/takeoutmenuz/app_1491153464434386 The application is designed to be responsive. I need an App to integrate my application with Facebook. The App must be installable on other Facebook pages to integrate with my shopping cart. Let me know if you have any questions and put the word yellow in the first sentence of your response.
