Merge product data

This is used to synchronise master product data from your environment into Flex. If a product doesn't exist, it is created, and if it does exist it is updated. You can also deactivate products by setting the deactivation_date.

Note, this endpoint should be used to synchronise master product data - if you have differing local product codes at an outlet level, use the product codes mapping endpoint to synchronise the mappings to your master data.
