Suppose A sent a transaction to SC(smart contract), including structured data, for example:


As usual, this transaction will be stored on all nodes in the network. Then, for some node X, how to get and deserialize this {"intention":"like","target":"ae16xx0...."},and make use of the data?

1 Answer 1


Yes there is. You can get this data from nodes that are running with the history_plugin plugin. You could use the HTTP API directly as in /v1/history/get_transaction, or you could use cleos:

cleos --url https://api1.eosdublin.io get transaction <Transaction ID>

You could also use eosjs:

const eosjs = require("eosjs")
const eos = eosjs({
  httpEndpoint: 'https://api1.eosdublin.io',
  chainId: 'aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906'

async function main() {
  const transaction = await eos.getTransaction('<Transaction ID>')

main().catch(error => {

You then just need to inspect the data that is returned and you will find the actions executed in the transaction and their respective parameter data.
