# eth\_getTransactionByHash - GIWA

Example code for the eth\_getTransactionByHash JSON-RPC method. Complete guide on how to use eth\_getTransactionByHash JSON-RPC in GetBlock Web3 documentation.

This method returns the transaction identified by its 32-byte hash, including its block placement once mined. It is the primary way to look up a specific transaction on GIWA.

## Parameters

| Parameter       | Type   | Required | Description              |
| --------------- | ------ | -------- | ------------------------ |
| transactionHash | string | Yes      | 32-byte transaction hash |
