getTransaction

getTransaction fetches a single confirmed transaction by its base-58 signature and returns its decoded contents along with execution metadata — fees, balance changes, inner instructions, log output, and compute units consumed.

Use it to inspect the outcome of a transaction you have already submitted (for example after sendTransaction), to confirm whether it succeeded, or to render the details of any historical transaction. The method returns null when no confirmed transaction matches the supplied signature — either because the signature is unknown to the cluster or because it has not yet reached the requested commitment.

Versioned transactions (those using Address Lookup Tables) are only returned when you pass maxSupportedTransactionVersion. If you omit it and the transaction is a versioned one, the request fails rather than returning the transaction.

JSON-RPC params is a positional array: [signature, config?].

When no confirmed transaction matches the signature, result is null:

{ "jsonrpc": "2.0", "id": 1, "result": null }

Errors are returned in the standard JSON-RPC error envelope. See the shared errors reference for the full envelope shape and shared codes.

A signature that simply does not match any confirmed transaction is not an error — the call succeeds with result: null.

JavaScript (fetch)

const res = await fetch("https://api.triport.io/v1/sol", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.TRIPORT_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "getTransaction",
    params: [
      "4eEzpJ29YBE7iz6Lw5eVNqYpJEMRDM6kF1pPyDmwbDgTynxJgF6Th9oV66XSh1jKvxhqZpKjJqLBu7nGzrjnVqWv",
      { encoding: "jsonParsed", commitment: "finalized", maxSupportedTransactionVersion: 0 },
    ],
  }),
});


const { result } = await res.json();
if (result === null) {
  console.log("Transaction not found");
} else {
  console.log(`Succeeded: ${result.meta.err === null}, fee: ${result.meta.fee} lamports`);
}

TypeScript SDK (@triport/sdk)

import { TriportClient } from "@triport/sdk";


const client = new TriportClient({ apiKey: process.env.TRIPORT_API_KEY });


const tx = await client.solana.getTransaction(
  "4eEzpJ29YBE7iz6Lw5eVNqYpJEMRDM6kF1pPyDmwbDgTynxJgF6Th9oV66XSh1jKvxhqZpKjJqLBu7nGzrjnVqWv",
  { encoding: "jsonParsed", commitment: "finalized", maxSupportedTransactionVersion: 0 }
);


if (tx === null) {
  console.log("Transaction not found");
} else {
  console.log(`Slot ${tx.slot}, fee ${tx.meta.fee} lamports, ok=${tx.meta.err === null}`);
}

Python (triport-sdk)

import os
from triport import TriportClient


client = TriportClient(api_key=os.environ["TRIPORT_API_KEY"])


tx = client.solana.get_transaction(
    "4eEzpJ29YBE7iz6Lw5eVNqYpJEMRDM6kF1pPyDmwbDgTynxJgF6Th9oV66XSh1jKvxhqZpKjJqLBu7nGzrjnVqWv",
    encoding="jsonParsed",
    commitment="finalized",
    max_supported_transaction_version=0,
)


if tx is None:
    print("Transaction not found")
else:
    print(f"Slot {tx['slot']}, fee {tx['meta']['fee']} lamports, ok={tx['meta']['err'] is None}")

• Always handle null. A successful response with result: null means the signature is unknown at the requested commitment — it is not an error.
• Versioned transactions: pass maxSupportedTransactionVersion: 0 to fetch current versioned transactions. Omitting it causes versioned transactions to fail rather than return.
• Confirmation lag: a freshly submitted transaction may not appear immediately. Poll with commitment: "confirmed" (or processed) for faster visibility, then re-read at finalized once settled.
• Related methods: use sendTransaction to submit a transaction, getSignaturesForAddress to discover signatures for an account, and getBlock to fetch every transaction in a slot.
