This path parameter specifies the unique eBay-assigned ID of the shipment associated with the shipping label you want to download. The shipmentId value is generated and returned by a call to createFromShippingQuote.
Note: Identifiers, such as order IDs or user IDs, and personal data in these samples might be anonymized or may no longer be active on eBay. If necessary, substitute current, relevant eBay data in your requests.
Sample 1: Download a shipping label
When you create a shipment with createFromShippingLabel, a pre-paid shipping label is created that you can use to ship the package via the selected shipping carrier. Use this method to download the printing label for your shipment. Note that you can also download the label using the URL returned in the response body of your createFromShippingLabel call.
Supply the shippingQuoteId as a path parameter in your request.
