Description

Returns the transaction with hash or null if the transaction is unknown.

If a transaction has not been mined, this method will search the transaction pool. Various backends may have more restrictive transaction pool access (e.g. if the gas price is too low or the transaction was only recently sent and not yet indexed) in which case this method may also return null.

Parameters

TransactionResponse object parameters

Example Request and Response

Prerequisite: You will need to install the Alchemy SDK before making requests with it.

The commands for installing it using npm or yarn are given below:

npm install alchemy-sdk

yarn add alchemy-sdk

Request

// Imports the Alchemy SDK
const { Alchemy, Network } = require("alchemy-sdk");

// Configures the Alchemy SDK
const config = {
    apiKey: "alchemy-replit", // Replace with your API key
    network: Network.ETH_MAINNET, // Replace with your network
};

// Creates an Alchemy object instance with the config to use for making requests
const alchemy = new Alchemy(config);

const main = async () => {
    // define the transaction hash
    const txHash = "0x88df016429689c079f3b2f6ad39fa052532c56795b733da78a91ebe6a713944b";

    //Call the method to display the transaction based on the transaction hash
    const response = await alchemy.transact.getTransaction(txHash)

    //Logging the response to the console
    console.log(response)
}

main();

Response

Use Cases

Here are some potential use cases for the getTransaction method:

• Transaction status: You can use getTransaction to check the status of a transaction by its hash. If the transaction has been mined and confirmed, you will be able to see the block number and other details. If the transaction has not yet been mined, you can use getTransactionReceipt to get the current status.

• Transaction details: You can use getTransaction to retrieve the details of a transaction, including the sender and recipient addresses, the amount transferred, and the gas used. This information can be useful for auditing purposes or to reconcile your own records.

• Debugging: If you are experiencing issues with a transaction, you can use getTransaction to retrieve the details and identify the source of the problem. For example, if a transaction is failing due to insufficient gas, you can use getTransaction to confirm the gas limit and adjust it as needed.
