I'm using JSON-RPC call to connect to local bitcoin node on my clouding server. I could get all transactions with wallet name by using gettransactions. Now I need to get sender's address for each transaction but result contains only receivers' address. Following is response of gettransactions request. { "result": [ { "address": "bc1qd9mgd4ynryaw2kp0pzfjdxguhz9dzvs5vh0nfn", "category": "receive", "amount": 0.001, "label": "", "vout": 27, "confirmations": 1322, "blockhash": "000000000000000000074551080f954e790edfe6ad810ecebf4691e881175eaf", "blockheight": 660029, "blockindex": 106, "blocktime": 1607147554, "txid": "07ab59c8d3a204172887085258460d0058c20a9acdb451daa5ad4290cbd461b0", "walletconflicts": [], "time": 1607147511, "timereceived": 1607147511, "bip125-replaceable": "no" }, { "address": "bc1q6dh3h5e3qgku8u9s8y664844fj4fkm08n7cnwt", "category": "receive", "amount": 0.0011, "label": "", "vout": 9, "confirmations": 1313, "blockhash": "00000000000000000000960f4476a8552cac203eec6e0f826886b41fae402bec", "blockheight": 660038, "blockindex": 393, "blocktime": 1607153799, "txid": "af0885e4c1d10e935de525680c6c33d221ab506742b08e34a0322bba90b56fb0", "walletconflicts": [], "time": 1607152236, "timereceived": 1607152236, "bip125-replaceable": "no" }, { "address": "1L8ZNCibVVpPjJ8VJ1ALLuTjtctA4mzGPw", "category": "send", "amount": -0.001, "vout": 0, "fee": -0.00008536, "confirmations": 706, "blockhash": "0000000000000000000c3230522e267980bb990883cc0b36460ad3efc1f8fed4", "blockheight": 660645, "blockindex": 1049, "blocktime": 1607529332, "txid": "a2056e7a49bc608435713519bc038ed7da2e65f588495f36c6628f5ca6fe2d7d", "walletconflicts": [], "time": 1607528963, "timereceived": 1607528963, "bip125-replaceable": "no", "comment": " ", "to": "seans outpost", "abandoned": false }, { "address": "1L8ZNCibVVpPjJ8VJ1ALLuTjtctA4mzGPw", "category": "send", "amount": -0.0005, "vout": 1, "fee": -0.00008536, "confirmations": 705, "blockhash": "0000000000000000000994e21412109847caffa2bd990884f49461d53c047055", "blockheight": 660646, "blockindex": 844, "blocktime": 1607529675, "txid": "ddbe1dce4537926b6cf5bc1e222e5cd32de224cf346ca89251c127ce32226f30", "walletconflicts": [], "time": 1607529401, "timereceived": 1607529401, "bip125-replaceable": "no", "comment": " ", "to": "seans outpost", "abandoned": false } ], "error": null, "id": "curltest" }

How can I get sender's address ?

    What do you need the sender address for? Bitcoin doesn't really have such a concept. There are approximations but they're often wrong. If the goal is distinguishing multiple payments to determine who paid, the best practice is giving a different receiving address to for every payment. Dec 14 '20 at 19:04

Despite how it looks on most block explorers, Bitcoin doesn't really have a concept of a "sender address", at least not on the raw transaction level. What a transaction has is inputs and what block explorers do is go look up those inputs and guess the address that was used to create those UTXOs.
