Before enabling the Shopify interface customers and products should be mapped to QTRACA.
Mapping Customers
A customer in QTRACA can be mapped to a customer in Shopify by adding the Customer ID to the external reference of the customer.

The Customer ID can be found in the Url when you view a customer in Shopify.

Note: Customers will automatically be created in QTRACA if they do not exist. There is no need to manually setup customers prior to a sale when using the Shopify integration.
Mapping Products
A product in QTRACA can be mapped to a product in Shopify by adding the SKU (Stock Keeping Unit) to the external reference.
The SKU can be found in the inventory section of the product view in Shopify.
Note: If you do not enter an external reference in QTRACA the integration will try and find a product where the code in QTRACA matches the title in Shopify.
