This endpoint applies to dropoffs powered by AfterShip QR Code: When a shopper drops some return items at the location, the merchant's sytem should scan the QR code, extract the rma_number, dropoff_id, and then call this endpoint to mark the items as dropped.
For 3rd party droppoff service providers to call this endpoint on behalf of merchant: please note that you need to extract the organization_id
and use an API Key of that specific organization.
This dropoff ID can be found in the QR code generated at AfterShip Returns.
