# Create an API Integration in Legacy Packages

:::note
The ability to create legacy packages was deprecated in August 2019. All new packages are enhanced packages.
:::

1. Navigate to an existing legacy package.

2. Under Components, click **Add Component**.

3. Select **API Integration**.

4. Assign the appropriate scope for your integration.

   - **Perform server-to-server requests** is automatically selected for all API Integrations.
   - If this package contains an app, select **Perform requests on behalf of the user**.
   - Select the scope for your API calls. Assign only the scope your package needs.

5. Save the component.
