Key actions include creating and resizing the Google Pay button using `createButton` with `buttonSizeMode`. It demonstrates authorizing payments before processing by registering `onPaymentAuthorized()`, calling `loadPaymentData()`, and implementing the callback handler. Dynamic price updates are enabled by registering `onPaymentAuthorized` and `onPaymentDataChanged`, and implementing both functions after calling `loadPaymentData`. Note that authorize payments and Dynamic price updates do not support liability shift.\n"]]
