But for Transactions with SegWit data, the "Transaction Hash" will be different than the "Transaction ID".
In "SegWit Transactions", Witness data won't be included when computing the TXID, but all will be included for the HASH; so the two can't be used as the same term.
Read this if I didn't explained it well: https://bitcointalksearch.org/topic/m.52639722
But since OP is talking about a certain (non-SegWit-friendly) blockexplorer's data named "hash", yes it's the TXID
Just mentioned so users wont confuse TXID and HASH when they call decoderawtransaction or a json data from a transaction.
