# How to get your workspace ID

> Find the workspace ID required for Retrac API requests and integrations.

When you connect Retrac to other tools via the API, you need your **workspace ID** alongside your API key. The workspace ID tells Retrac which inventory catalog to read or write.

<Note>
  REST API access is available on **Business** plans and above. Create API keys under **Settings → API Keys**.
</Note>

## Find your workspace ID

<Steps>
  <Step title="Open workspace settings">
    Sign in to [app.retrac.co](https://app.retrac.co) and open the workspace you want to integrate with.
  </Step>

  <Step title="Go to General settings">
    Click **Settings → General** in the sidebar.
  </Step>

  <Step title="Copy the workspace ID">
    Copy the **workspace ID** shown on that page. It is a unique identifier for this workspace.
  </Step>
</Steps>

## Use the workspace ID in API requests

Include your API key in the `Authorization` header and pass the workspace ID for operations that require it:

```
Authorization: Bearer YOUR_API_KEY
```

See [API keys](/dashboard/api-keys/introduction), [Authentication](/api-reference/authentication), and [Retrieve a workspace](/api-reference/endpoint/retrieve-a-workspace) for full details.

<Tip>
  Each workspace has its own ID. If you belong to multiple workspaces, make sure you use the ID for the correct one in your integration.
