POST
When a card transaction triggers 3D Secure, a challenge is created for the customer to approve. Fetch pending challenges with GET /v1/customers/{customerId}/accounts/{accountId}/cards/3ds (optionally ?authId=...), show the transaction details, then confirm here with the authId and an action of approve or reject.
Instead of polling, receive challenges in real time over WebSockets — the pushed event’s data.id is the same authId you confirm with here.
