I am whitelisted for the Logistics API and can generate USPS & Fedex labels, but calling https://api.ebay.com/sell/logistics/v1_beta/shipping_quote returns no options for printing Ebay Standard Envelope labels. (FWIW I also don't get the option for UPS labels, but that doesn't really matter to me.)
All of my items are in collectibles categories that allow Ebay Standard Envelope for shipping, and even passing in a valid orderid doesn't give me the option. I do have the option in the Ebay shipping UI, but that doesn't work for my workstream.
I emailed regular ebay merchant support about this a few days ago and haven't gotten a response. Any one else trying to do this at this time?
