Where can I enter the article IDs for Lieferando?

In the Lieferando Partner Dashboard, the restaurant has the option to assign External IDs to the individual menu items (see the following image). The ID entered here will be passed on to the cash register system. Depending on the integration, the assignment to the POS items is made based on this ID or the name of the item. The procedure must be coordinated with the responsible POS vendor.
The restaurant or sales partner can also send an excel file to the responsible support agent containing the menu item name and menu item ID to assign the IDs.
