Implementers using Google Pay API V2 need to update their `PaymentDataRequest` object. This involves adding `merchantName`, `countryCode`, and `totalPrice`. Upon receiving a response, merchants might get an authenticated payload or a `PAN`, the latter requiring 3D Secure 2.0. Merchants should leverage PSPs or in-house risk management tools, using `assuranceDetailsRequired` and `cardHolderAuthenticated` to handle transactions requiring step-up authentication.\n"]]
