Hi Cathy,
We currently support Ebay, Amazon, and Etsy. Since the new payment service isn’t yet in the APIs, you wouldn’t be able to use our Payment Presets to manage these listings.
Every time you Submitted, Revised or Relisted one, you would have to add that service via Seller Hub.
If you’re using Business Policies and have that payment service in your Payment Policy created in Seller Hub, you could use SixBit, as we only send eBay the Payment Policy ID to use for your listing, and not the actual details.
