# Validio SDK Reference

> Every public module, class, and function in the Validio Python SDK, generated from its docstrings.

This reference documents every public module, class, and function in the `validio-sdk` Python package. To install the SDK and send your first request, see [About Validio SDK](https://docs.validio.io/v10.3/developer/validio-sdk.md). For worked examples, see the [SDK recipes](https://docs.validio.io/v10.3/developer/validio-sdk/sdk-recipes.md).

## How this reference is organized

The reference is generated from the docstrings in the `validio-sdk` package, one page per package: `validio_sdk`, which holds top-level modules such as `config`, `exception`, and `poll`, then `validio_sdk.client`, `validio_sdk.code`, and `validio_sdk.resource`. Each page documents the package's modules in turn, then what the package itself exports under **Module contents**. Private modules and members, and tests, are excluded.

> [!NOTE]
>
> `Client` is documented under `validio_sdk.client.client`, where it's defined. Import it from the package instead: `from validio_sdk.client import Client`.
