This application is an ecommerce application which create ecommerce website for customers.

Now, problem is that i want to develop an module for the base website in which the products from all the tanent’s website will be visible

For example:-

Base website – https://base.com/shoping

Will show all the products from all tanent’s websites-

https://customer1.base.com,
https://customer2.base.com,
etc.

Please suggest me the best way to achieve this.
