Problem Adding Return Tracking number for label already sent with Post Order API
I am trying to add a tracking number and carrier information for orders that have been approved with "APPROVE_WITHOUT_EBAY_LABEL" the buyer has already been sent the label with the original package, or via postal mail or email. On the eBay site we can select "Confirm You already sent a label" and add the carrier and tracking number and have it taken care of. Using the post order API "add_shipping_label" and setting the "forwardShippingLabelProvided" to "true" we always get an error asking for "fileId" we do not get an error asking for "labelId" even though the documentation says this is required. Neither of these values are available or exist as the buyer already has the label and the label file is not being uploaded to eBay. I am trying to mimic the same functionality that is available on the view return details page. Please help with how to avoid the fileId error.
