Use Case

The eth_getTransactionByHash method is particularly useful for retrieving detailed information about a specific transaction, which can be critical for verifying and tracking transactions on the Ethereum blockchain. In case of an eth_getTransactionByHash error, developers should verify that the provided transaction hash is correct and corresponds to an existing transaction. An eth_getTransactionByHash example can help developers understand the correct usage of this method.

Code Example

You can also make requests to the eth_getTransactionByHash method programmatically using Python. Below is an example using the requests library:

import requests
import json

# Define the API URL and access token
url = 'https://go.getblock.io/<ACCESS-TOKEN>/'
headers = {'Content-Type': 'application/json'}

# Prepare the request data
data = {
    "jsonrpc": "2.0",
    "method": "eth_getTransactionByHash",
    "params": [
        "0xcd718a69d478340dc28fdf6bf8056374a52dc95841b44083163ced8dfe29310c"
    ],
    "id": "getblock.io"
}

# Send the POST request
response = requests.post(url, headers=headers, data=json.dumps(data))

# Parse the JSON response
response_data = response.json()

# Print the result
print(json.dumps(response_data, indent=4))

const axios = require('axios');

// Replace ACCESS_TOKEN with your actual Access Token
const url = 'https://go.getblock.io/ACCESS_TOKEN/';

// Request payload
const payload = {
  jsonrpc: '2.0',
  method: 'eth_getTransactionByHash',
  params: [
    '0xcd718a69d478340dc28fdf6bf8056374a52dc95841b44083163ced8dfe29310c', // Transaction hash
  ],
  id: 'getblock.io',
};

// Axios POST request
axios
  .post(url, payload, {
    headers: {
      'Content-Type': 'application/json',
    },
  })
  .then((response) => {
    console.log('Response:', response.data);
  })
  .catch((error) => {
    console.error('Error:', error.message);
  });

This Python script sends a request to the eth_getTransactionByHash method and prints the returned transaction information. Make sure to replace <ACCESS-TOKEN> with your actual API token. This script serves as an eth_getTransactionByHash example for developers to understand the implementation in Python.

The Web3 eth_getTransactionByHash method can also be used in Web3 libraries for Ethereum, providing an interface to access detailed transaction data based on a specific transaction hash.
