LedgerService/GetTransaction - SUI

Example code for the LedgerService/GetTransaction gRPC method. Complete guide on how to use LedgerService/GetTransaction gRPC method in GetBlock Web3 documentation.

Returns a transaction by its digest, including the full effects, events emitted, and inputs/outputs. The optional read_mask lets you fetch just the parts you need — for example, requesting only effects.status is significantly cheaper than fetching the full transaction body.

Service: sui.rpc.v2.LedgerService Proto file: sui/rpc/v2/ledger_service.proto Full method path: sui.rpc.v2.LedgerService/GetTransaction

Request Fields

Field	Type	Required	Description
digest	string	Yes	Transaction digest (Base58)
read_mask	FieldMask	No	Field paths — e.g. ["digest", "effects", "events"]. Use ["*"] for all fields

Response Example

Responses are encoded in Protocol Buffers binary format on the wire. The example below shows the protobuf JSON encoding for readability.

Response Fields

Field	Type	Description
transaction.digest	string	Transaction digest (echoed)
transaction.transaction.data	TransactionData	The transaction body — sender, gas, kind
transaction.effects.status	ExecutionStatus	success: true or error with details
transaction.effects.gas_used	GasCostSummary	Computation cost, storage cost, and storage rebate (all in MIST)
transaction.effects.mutated	repeated ObjectRef	Objects modified by this transaction
transaction.events	repeated Event	Move-level events emitted by the transaction
transaction.checkpoint	string	Checkpoint sequence number containing this transaction
transaction.timestamp_ms	string	Block timestamp in milliseconds

Use Cases

• Confirming a submitted transaction succeeded after broadcast

• Reading emitted events for indexers

• Computing actual gas cost for accounting

• Building transaction detail views in explorers

Error Handling

gRPC uses status codes rather than JSON-RPC numeric error codes. The most relevant for this method:

Status Code	Numeric	Cause
UNAUTHENTICATED	16	Missing or invalid <ACCESS-TOKEN> in the URL path
INVALID_ARGUMENT	3	Request fields are missing, malformed, or fail validation
UNAVAILABLE	14	Node is overloaded or temporarily unable to handle the request — retry with backoff
DEADLINE_EXCEEDED	4	Request did not complete within the timeout window
RESOURCE_EXHAUSTED	8	Rate limit exceeded for your plan
NOT_FOUND	5	No transaction exists at the requested digest, or it has been pruned from this node

SDK Integration

@mysten/sui (TypeScript)

// The Mysten Labs TypeScript SDK provides higher-level wrappers around the
// gRPC API. Use @mysten/sui for typed client access:

import { SuiClient } from '@mysten/sui/client';

const client = new SuiClient({
    url: 'https://go.getblock.io/<ACCESS-TOKEN>/'
});

// Refer to the @mysten/sui API reference for the typed wrapper of this method;
// raw gRPC call to sui.rpc.v2.LedgerService/GetTransaction is available as shown in the
// Request Example tabs above.

pysui (Python)

# pysui is the community-maintained Python SDK for Sui (Mysten Labs does not
# yet publish an official Python SDK). For raw gRPC access, use grpcio with
# the generated proto stubs as shown in the Request Example tabs above.

from pysui import SuiConfig, SyncClient

config = SuiConfig.user_config(
    rpc_url='https://go.getblock.io/<ACCESS-TOKEN>/'
)
client = SyncClient(config)

# Consult pysui docs for the wrapper of LedgerService.GetTransaction.
