Good quesiton. Generally it won't, but you can not exclude the possibility. The decision is still ultimately hold by the issuer bank, they can require 3DS even if it is succeeded before

You would need to make sure you can handle such cases

OK, thank you. If 3DS is needed, then the intent gets state requires_action, right?

[quasi schooner]

Yep

[cosmic oar]

In which case can requires_confirmation still occure, if the payment intent was created with {confirm: true}?

[quasi schooner]

if it is straight declined with, for example do_no_honor

ie. if the bank flagged this customer as fraud, they can decide to decline every transactions without further authentication challenger

Or simply if they have some thing wrong in their system

In that case, propose your customer to key in a different card, to recover one of your sale

[cosmic oar]

OK, thank you very much! Then in both cases should happening at this point, I can handle the payment in our system as failed. You helped me very much! Thank you!
