Description

#1575
After an updateIntent flow completes, the SDK returns a new sdkAuthorization. All subsequent confirm calls must use this updated token. Inside the iframe, usePaymentIntent reads sdkAuthorization from the Recoil keys atom at render time and closes over it in the returned intent function. Each payment method component memoizes its submitCallback via React.useCallback — if sdkAuthorization is not in the dependency array, the callback captures a stale intent with the old token even after the Recoil atom is updated.

Root cause: sdkAuthorization was missing from the useCallback dependency array in all payment method submitCallback hooks. This caused the confirm API call to be made with the pre-updateIntent authorization token, resulting in an auth failure.

Fix: Added sdkAuthorization (from the keys Recoil atom) to the useCallback dependency array in all affected payment method components. For components that did not already destructure sdkAuthorization from keys, the destructuring was updated accordingly.

How did you test it?

Tested manually using the Hyperswitch React Demo App:

1. Loaded the payment form with EPS selected (required fields pre-filled, no user input needed)
2. Clicked "update use elements + confirm" — which calls elements.updateIntent(...) then hyper.confirmPayment(...)
3. Before fix: confirm API call used the old sdkAuthorization, resulting in an auth error
4. After fix: confirm API call correctly used the new sdkAuthorization returned by updateIntent, payment proceeded successfully
   Also verified the same flow with Trustly (no required fields) and other bank redirect / bank debit / bank transfer payment methods continued to work correctly.
