# getblocktransactionsext - TON

Example code for the getblocktransactionsext JSON-RPC method. Сomplete guide on how to use getblocktransactionsext JSON-RPC in GetBlock.io Web3 documentation.

This method returns the list of transactions in a block, with extended information for each transaction, avoiding the need for a second round trip to fetch full transaction details.

## SDK Integration

{% tabs %}
{% tab title="@ton/ton (JavaScript)" %}

```javascript
import { TonClient } from '@ton/ton';

const client = new TonClient({
    endpoint: 'https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>'
});

// The @ton/ton client wraps the same JSON-RPC methods.
// For low-level access, use client.callGetMethod or client.provider.
```

{% endtab %}

{% tab title="pytoniq (Python)" %}

```python
from pytoniq import LiteClient
# For HTTP API access, use ton-http-client or call the JSON-RPC
# endpoint directly with requests as shown in the Request Example.
```
