Bitcoin or Litecoin Core: return payment to sender

[Knight Hider]

How to get a transaction input address, like block explorers do, directly from Core client? I need it to return a payment to one of the sending addresses.

litecoin-cli gettransaction:

Code:

{
  "amount": 0.00005851,
  "confirmations": 2,
  "blockhash": "1ee0005f20625b4dda47cff35a0214940d5c0e8f33cc42054a9ffa3e1370583d",

      "amount": 0.00005851,
      "label": "",
      "vout": 1
    }
  ],
  "hex": "020000000001015ed7d1b7f75e3e3c0901b97fa96095d8e3a2d8fdaad07ff5b2e0d0bbd7e12ecf0100000000feffffff02327d030000000000160014ce295448dda30f95852504b78071b3dd23b68232db16000000000000160014cb1183f09b199b16022c12f60b89eb02891904c70247304402201b4a01969140b75d66b797718819d0fcc6538962d666298b9d020db3a9e47b8e022020dea3ec9ecbdb244c3c745555e7e0a553f81785292fa3233209b5bce8009b2801210276771913879beb7efe864f26486987637d06649c01d362dbc3a8d94a35556f7d0d6b2900"
}

I use Litecoin for testing because it works better than Testnet

Is this possible without txindex=1?I use a pruned node.

Is this possible without txindex=1?I use a pruned node.

Quite possible, if the block where the transaction is still not pruned or if it's still in your mempool,
You can use getrawtransaction in your Bitcoin Core node even without txindex by providing the hash of the block where the transaction is included.
Then use verbosity "2" to include "prevout" to each of the inputs in the result.

For example, test the first non-coinbase transaction in current latest block height 850758 with the block hash 00000000000000000000a8e2c7fcd3b21caa2da453d956f86ec1e77ff39fd0b8.
That block should still be available in your Bitcoin Core's blocksdir I suppose, command:

Code:

getrawtransaction "cfb247517f143c0bf5b1ffeca8789f29000c64881e3ed992976a954b58b024d0" (2, "00000000000000000000a8e2c7fcd3b21caa2da453d956f86ec1e77ff39fd0b8")

Result:

But if the block is already pruned, it wont work. You'll have to use txindex and intact blockchain.

This works in Bitcoin Core but not in Litecoin Core. Github issue: https://github.com/litecoin-project/litecoin/issues/948
The block is not pruned yet when I need this.
