Dear Mohammed,

I have done this ayear and a half ago or so, without using any Marketplace Modules, so I couldn’t tell you about thos. But basically I made a shoppingcart-module that had non-persistable entities that mirrored my product and that were being filled in with the required values of my non-persistable shopping cart attributes (amounts, total price etc). Then, only when the shopping cart gets payed for, I actually change the inventory numbers of the BackOffice persistable entities and change anything in the dB.

So the main idea of the seperate module with non-persistable entities is that you want no changes made to your dB as long as the shopping cart hasn’t been payted for and emptied again: this info should only exist in the session, which is why the non-persistables are perfect for this.

Best of luck!

Would also love to see some starter project with shopping cart functions.

Here are some options:

• see what Andy made in 2017: https://github.com/andylushman/E-Commerce-Store, update widget ‘Mobile Features’ and you’re good to go. Got a product page and a good part of the cart- and order-functionalities.
• ask Mendix to fork their shop: https://mendixshop.mendixcloud.com/index3.html.
• contact https://forum.mendix.com/link/space/studio%20pro/questions/115737, ask for a copy/fork.
• https://www.mendix.com/solutions/omnichannel-integration-layer/ “Brick-and-Mortar e-Commerce“, but no code or project there, just a picture.
• ask Robin Bozhurin about https://github.com/rbozhurin/Mendix (which is empty, but he at least intended to build a shop in Mendix)

Searched github.com/mendix, nothing.
