# packaddress - TON

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

This method packs a raw `workchain:hex` address into the user-friendly base64 form. Equivalent to a one-shot conversion utility.

## Parameters

| --------- | ------ | -------- | ------------------------------------- |
| address   | string | Yes      | Address in raw form (`workchain:hex`) |

## 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.
```
