How does the Shop app receive notifications from a WooCommerce-based store?

[robmiracle]

I'm helping a client set up a WooCommerce-based site using Printify to process the products. In an order that we placed to test everything, I got an unexpected shipment notification in the Shop app on my iPhone. The name of the shop is picking up my domain name as who the product is from and not the name of the shop's website site.

Printify says they have no connections to Shopify and only connecting with the WooCommerce shop. I don't see anywhere that the Shop app should be getting any information as we've not set up any integration.

Does anyone have any information on how the Shop app gets notifications from a WooCommerce-based shop?

Thanks
