How to get a transaction by transaction hash

Step 1: Setup Moralis

Read the article Setting Up Moralis: Getting Started and make sure to finish all the steps. Only after that you can go ahead to complete this guide.

Step 2: Get a transaction by transaction hash

In order to get a transaction by hash, Moralis provides you a getTransaction endpoint to do so.

Here you'll need two parameters: transactionHash and chain.

Once you've obtained both the transactionHash and chain, you can copy the following code:

index.js (JavaScript)

const Moralis = require("moralis").default;
const { EvmChain } = require("@moralisweb3/common-evm-utils");

const runApp = async () => {
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...and any other configuration
  });

  const transactionHash =
    "0xaae93882e8a9fe9ff30151853db20e4cd161940757a01744465ab83b751c5875";

  const chain = EvmChain.ETHEREUM;

  const response = await Moralis.EvmApi.transaction.getTransaction({
    transactionHash,
    chain,
  });

  console.log(response.toJSON());
};

runApp();

index.ts (TypeScript)

import Moralis from "moralis";
import { EvmChain } from "@moralisweb3/common-evm-utils";

const runApp = async () => {
  await Moralis.start({
    apiKey: "YOUR_API_KEY",
    // ...and any other configuration
  });

  const transactionHash =
    "0xaae93882e8a9fe9ff30151853db20e4cd161940757a01744465ab83b751c5875";

  const chain = EvmChain.ETHEREUM;

  const response = await Moralis.EvmApi.transaction.getTransaction({
    transactionHash,
    chain,
  });

  console.log(response.toJSON());
};

runApp();

index.py (Python)

from moralis import evm_api

api_key = "YOUR_API_KEY"

params = {
    "transaction_hash": "0xaae93882e8a9fe9ff30151853db20e4cd161940757a01744465ab83b751c5875",
    "chain": "eth",
}

result = evm_api.transaction.get_transaction(
    api_key=api_key,
    params=params,
)

print(result)

Step 3: Run the script

To run the script, enter the following command:

Shell (JavaScript)

node index.js

Shell (TypeScript)

ts-node index.ts

Shell (Python)

python index.py

In your terminal, you should see the following JSON response:

    }
  ]
}

Congratulations 🥳 you just got the transaction content of a transaction by its transaction hash with only a few lines of code using the Moralis Transaction API!
