# Step 17 (alternative): Integrate the Digital River components into an asynchronous checkout flow

{% hint style="info" %}
**Note:**  This step is used to configure the asynchronous checkout flow. If you are implementing the synchronous checkout flow, alternatively follow the steps in [Step 18: Integrate the Digital River components into the synchronous checkout flow](/salesforce-lightning/salesforce-lightning-b2b-commerce-app-1.4/integrate-the-salesforce-lightning-app/step-18-alternative-integrate-the-digital-river-components-into-a-synchronous-checkout-flow.md).
