The GetFulfillmentIdentifierForMSKU operation gets the Fulfillment Network SKU (FNSKU) for each supplied merchant item—creating one if needed. This operation is idempotent in that you can call it multiple times without any adverse effects. This operation is required whenever you need to register items for Amazon fulfillment that require labeling. This operation is necessary to register items for Amazon fulfillment in order to send them to Amazon, but doesn't mark any offer for this item as Amazon fulfilled.
A response does not imply that the item has an offer for which it can be fulfilled; only that the Amazon Fulfillment Network can track it. An inactive item can have a quantity in the fulfillment center, but will never be fulfilled.
Use this operation instead of GetFulfillmentIdentifier if an offer already exists for the SKU.
