HppPostMessage
The shape of every window.postMessage the hosted page sends to its
parent/opener. Not an HTTP payload: this is what you receive in a
browser message event's event.data. See the integration guide
above for the full listener example. There are only two message
types; every way a checkout can end (finished, canceled, timed out,
or never loaded) is an outcome of result, not a separate type.
