txids property
The transaction ids this send minted, hex, in mint order — the identifiers SendOutcome deliberately does not carry (it is SHARED with the shield and move-to-transparent flows, which have no host to report to, and it counts rather than identifies).
Present on every arm that MINTED a transaction, whatever the endpoint said
about it — a broadcast failure is data, not a lost payment. Empty for the
arms where nothing was created (a refused sign, an already-consumed token),
and empty for a send whose results carried no id at all (the forward-compat
TxSubmitResult.unknown).
Used by the FR-26 host report; the result screen renders counts, never ids.
Implementation
