Transaction authorization code needed


#1

My attempt to make a purchase online ended in such an e-mail:

That charge was assigned an “authorization” or “approval” code. We need you to contact your credit card provider/bank and give us that authorization/approval code in order to confirm that you are the cardholder. We already know what the authorization code is; we simply need you to verify that code with us before we can accept your credit card as a form of payment.

The authorization/approval code might show up on your online statement, but this could take quite a few days. Many credit card provider/banks can easily give this authorization code to you over the phone. We find that calling your bank is the quickest way to get your order confirmed and on its way to you.

I have downloaded the statement using the app, but it does not have the code mentioned in the quote above. How could I obtain it?
This issue looks similar to Statement Code?.

I guess in your case what you need is a card with a 3D secure verification system. This is actually not provided by Revolut

Having seen 3D Security in action, I do not think it is the case.
I assume seller request some kind of transaction ID which I am not able to see.
