Definitely a scam, and I'm very sorry you were targeted. Scammers have been hitting new Sellers as well as seasoned ones. "Verification" and QR Codes is one of the scams, as well as posing as Etsy Staff/Support, etc. When you receive a LEGIT Message from Etsy Support/Staff, etc., it will appear in the "From Etsy" Folder (in Messages). If it isn't there, Mark the Message as Spam (so you don't get dinged for S Seller). *"From Etsy" Folder was not on the App until recently (a highlighted blurb on the Message). The thing is, should you not see this first (and be familiar with it), you could receive a scammer's Message beforehand. Also, the App does not allow you to Mark the Message as Spam (you must use a browser instead, or use the Buyer App).
Also for future, many scammers are posing as "Buyers", stating they need your email for an Order. They don't, Etsy already has it. When you receive a LEGIT Order, it will appear in "Orders & Shipping" (Left Column of Shop Dashboard); if it isn't there, you have no Order. Mark the scammer's Message as Spam (so you don't get dinged for S Seller). And never click on links or engage with them.
Etsy should be able to nail these FAKE accounts who are impersonating Etsy Staff/Support, etc. It's happening way too often. Here is the Announcement about the "From Etsy" Folder (currently this is in past Announcements).
