Parse Transactions

Parse transactions into human-readable data.

Deprecated: The Enhanced Transactions API is deprecated and no longer receiving new parser types or feature work. Existing endpoints continue to operate, but new integrations should use getTransaction or getTransactionsForAddress directly.

Overview

The Parse Transactions endpoint transforms raw transaction signatures or data into structured, human-readable information. Instead of manually decoding instruction data and account lists, you receive clear details about transfers, swaps, NFT activities, and more.

Quickstart

Parse one or more transaction signatures with a single API call:

JavaScript

const parseTransaction = async () => {
  const url = "https://api-mainnet.helius-rpc.com/v0/transactions/?api-key=YOUR_API_KEY";

  const response = await fetch(url, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      transactions: ["5rfFLBUp5YPr6rC2g1KBBW8LGZBcZ8Lvs7gKAdgrBjmQvFf6EKkgc5cpAQUTwGxDJbNqtLYkjV5vS5zVK4tb6JtP"],
    }),
  });

  const data = await response.json();
  console.log("Parsed transaction:", data);
};

parseTransaction();

Python

import requests
import json

def parse_transaction():
    url = "https://api-mainnet.helius-rpc.com/v0/transactions/?api-key=YOUR_API_KEY"
    
    payload = {
        "transactions": ["5rfFLBUp5YPr6rC2g1KBBW8LGZBcZ8Lvs7gKAdgrBjmQvFf6EKkgc5cpAQUTwGxDJbNqtLYkjV5vS5zVK4tb6JtP"]
    }
    
    response = requests.post(url, json=payload)
    data = response.json()
    print("Parsed transaction:", data)
    
parse_transaction()

Response Structure

Enhanced transaction responses include structured data with human-readable descriptions:
