# Introduction

> Build embedded shopping experiences - product discovery, universal cart, and order management - with a single SDK

The **Henry SDK** gives your application a full commerce stack out of the box. Search any merchant's catalog, build multi-merchant carts, launch checkout in seconds, and track orders - all through a type-safe TypeScript SDK backed by a single API key.

## Get started in minutes

<Steps>
  <Step title="Get your API key">
    Go to the [Henry Dashboard](https://app.henrylabs.ai) and create an app to get your API key.
  </Step>

  <Step title="Install the SDK">
    <CodeGroup>
      ```bash npm theme={null}
      npm install @henrylabs/js
      ```

      ```bash bun theme={null}
      bun add @henrylabs/js
      ```

      ```bash pnpm theme={null}
      pnpm add @henrylabs/js
      ```

      ```bash yarn theme={null}
      yarn add @henrylabs/js
      ```
    </CodeGroup>
  </Step>

  <Step title="Initialize the client">
    ```typescript theme={null}
    import HenrySDK from '@henrylabs/sdk';

    const henry = new HenrySDK({
      apiKey: process.env.HENRY_SDK_API_KEY!,
    });
    ```

    <Info>
      Always initialize server-side. Your API key must never be exposed in browser or mobile code.
    </Info>
  </Step>

  <Step title="Make your first request">
    ```typescript theme={null}
    const search = await henry.products.search({ type: 'global', filters: { type: 'text', query: 'Nike Air Max' } });

    // poll until results are ready
    let result = search;
    while (result.status === 'pending' || result.status === 'processing') {
      await new Promise(r => setTimeout(r, 1000));
      result = await henry.products.pollSearch({ refId: search.refId });
    }

    console.log(result.result?.products[0]);
    ```
