    App Store Server Notifications V2 is Apple's webhook surface for in-app
    purchase and subscription lifecycle events. Apple POSTs a JWS-signed payload
    to the production and sandbox URLs registered in App Store Connect every
    time a transaction or subscription state changes. The signed payload wraps
    the responseBodyV2DecodedPayload, which contains the notificationType, an
    optional subtype, the JWSTransaction, and (for subscription events) the
    JWSRenewalInfo. Providers verify the JWS with Apple's certificate chain and
    then react to the notification.
