How to Get a Blockchain Transaction by Hash

Introduction

In this tutorial, you’ll learn how to retrieve detailed information about any blockchain transaction using its hash. This is essential for building transaction explorers, tracking payments, or verifying on-chain activity in your application. We’ll use the following Moralis API endpoint:

Get Transaction by Hash - Fetch detailed transaction data using a transaction hash

Prerequisites

Node.js v18+ installed
A Moralis API key (get one free)

Step 1: Set Up Your Project

Create a new directory for your project and initialize it:

mkdir get-transaction && cd get-transaction
npm init -y

Step 2: Create the Script

Create a file called index.js and add the following code:

// index.js
const API_KEY = 'YOUR_API_KEY';
const TX_HASH = '0x5c504ed432cb51138bcf09aa5e8a410dd4a1e204ef84bfed1be16dfba1b22060';

async function getTransaction() {
  const response = await fetch(
    `https://deep-index.moralis.io/api/v2.2/transaction/${TX_HASH}?chain=eth`,
    {
      headers: {
        'X-API-Key': API_KEY,
      },
    }
  );

  const data = await response.json();
  console.log(JSON.stringify(data, null, 2));
}

getTransaction();

Replace YOUR_API_KEY with your actual Moralis API key.

Step 3: Run the Script

Execute the script to fetch the transaction details:

node index.js
