I got this transaction outputs from bitcoin-qt gettransaction c9c3e63c2e94f643957a6980689c7b2b80eeb645c6f3a47dd0b551c8c4de6cc7 { “amount” : 0.00000000, “fee” : 0.00000000, “confirmations” : 1215, “blockhash” : “00000000000000001b295c20166ff208e6cbb45317bc1c0046c1b496fba11de8”, “blockindex” : 30, “blocktime” : 1408959427, “txid” : “c9c3e63c2e94f643957a6980689c7b2b80eeb645c6f3a47dd0b551c8c4de6cc7”, “walletconflicts” : [ ], “time” : 1408959427, “timereceived” : 1409566299, “details” : [ { “account” : “”, “address” : “1LYUg6Vf3xHsGZNWqbUkqX2pPWBV6jsUGR”, “category” : “send”, “amount” : -2.50050000, “fee” : 0.00000000 }, { “account” : “”, “address” : “1GS527HMj5iv5F2m26C84QzCCVek5pArje”, “category” : “send”, “amount” : -0.42010000, “fee” : 0.00000000 }, { “account” : “520c7bb149ede83218f46c96”, “address” : “1LYUg6Vf3xHsGZNWqbUkqX2pPWBV6jsUGR”, “category” : “receive”, “amount” : 2.50050000 }, { “account” : “520c7bb149ede83218f46c96”, “address” : “1GS527HMj5iv5F2m26C84QzCCVek5pArje”, “category” : “receive”, “amount” : 0.42010000 } ], “hex” : “0100000001c787eb10af208c22484ff037ec17f1fbf44ff8e85af8e5cd08d7fa133d254fc0000000006b483045022100e00869aba056388aadea6ee9e82b6834822a6e5719ce1d3b8ddf8e394e826432022064fb9d133a20c1a4cb1c0fa66db2ceea5a787e9b38dd15be1384ba47dc23a69a0121034ef6e5a1d33180a5899d54816ae27784d0eb5f0269dde87b218d904a9f67da7dffffffff03d075e70e000000001976a914d65e62c64c8ecf246b1eaa6f3a567da300d0f04d88acd0d4ab04000000001976a9149a0875284b705871f158a45d9eb89bf0ed12428088ac90058102000000001976a914a947a40a737c889cac29ba8391c73b8cc0fc7b1188ac00000000” }

Could you please explain it to me I’m little bit confused !

The difference that I noticed is the transaction has 4 outputs from bitcoin-qt while it shows 3 outputs from blockchain ! please correct me if I am wrong. Thank you in advance

gettransaction is a wallet RPC that shows the effects of a transaction on your wallet. It doesn’t show the raw Bitcoin transaction itself. Use getrawtransaction for that (which needs a full transaction index, you’ll need to set txindex=1 in bitcoin.conf, and reindex).

Alternatively, get the hex field from gettransaction output, and pass it to decoderawtransaction

Closing as “intended behavior”.

First of all thank you for your quick reply. I did the getrawtransaction command and I got this response : No information available about transaction

for the other option get the “hex” field and pass it to “decoderawtransaction” I saw that the outputs were correct it showed me three outputs. So let me explain the case , it comes from send bitcoin to myself “Payment to yourself” but I specified the receive address without specify the send address , so why it shows the send also ? in the normal case it shows just the receive address in transaction details!

The problem now is that I relay on gettransaction in my business logic, is it not precise enough ? should I change it to decoderawtransaction to get precise information ? Thank you again.

gettransactions simply does not give you inputs and outputs. It gives you “ledger entries” - effects that this transaction has on your wallet. If it contains an output that credits an address of yours, that will be represented as a receive, if it spends coins of yours they will be represented as a send (though with change subtracted).

If you’re not interested in the wallet effects, but just in the actual inputs and outputs at the Bitcoin transaction level, yes, you’ll have to use the raw data.

Also, getrawtransaction will not work unless you have a transaction index. Use @laanwj’s suggested instead.

His problem is, the gettransaction does not show the NET effect this transaction had in his wallet. If you take a close look, the same details are shown as both received and sent. Same address same amount only with different category. Normally, gettransaction is supposed to show only 2 out of 3 outputs that this transaction has. Out of three outputs of the transaction 2 addresses belong to him. His wallet should show those two as details. The code he pasted shows that the transaction had 0 effect on his wallet. Which shows wrong behavior. I think he understands gettransaction but there is a problem with his case.

He reported this to be a send to self. Bitcoin is expected to report the payments to non-change addresses, and for both reports both a send and a receive. That seems to be working as intended to me.

Ah sorry. So but shouldn’t the input address be shown as sent and the two outputs be displayed as received in the transaction details in that case? Why are the outputs being shown as sent and received and the input is not in the details at all?

There is no such thing as an input address. He sent to 1LYUg6Vf3xHsGZNWqbUkqX2pPWBV6jsUGR and 1GS527HMj5iv5F2m26C84QzCCVek5pArje, and at the same time since those are addresses in his wallet, also received with 1LYUg6Vf3xHsGZNWqbUkqX2pPWBV6jsUGR and 1GS527HMj5iv5F2m26C84QzCCVek5pArje.

True I meant sending and receiving with input & output. I understand thanks
