You generally should listen to the transaction’s “complete” event instead of
the put/add request’s “success” event, because the transaction may fail after
“success.” There’s at least one example of someone being confused by the
wording[1]. Perhaps the spec should point out that you usually want to listen
to “complete” for write requests.
Use of a write request’s “success”/“error” events is probably reserved for
advanced use cases (e.g. to commit part of a transaction even when the later
requests fail, or to retry a write that failed, or to measure progress when a
transaction has multiple parts).
