Winstore expects to be always provided by a customerID, independent of which application is connected apart from the integration. Since normally webshops do not provide a CustomerID by default, this is not configured by default. Hence an adjustment in the default mapping is required in order for the orders to work correctly.
- Select the SalesOrder flow.
- Navigate to the default data mappings.
- Scroll down until you find the debtor identification. And make sure both sides are filled out with the customer information. Winstore should be filled by default, but the secondary application is usually empty. Below an example of how this should be filled in. Note: field name can differ for different applications. The example is from Shopware.
