# Checkout Integration

Commerce checkout provides integration points to third-party services.

**note:** In the Winter ‘24 release, we introduced Commerce extensions for pricing, inventory, shipping, taxes, and other services. While the checkout integrations framework is still supported, we recommend extensions over integrations because they offer more targeted customizations for your B2B or B2C store. Plus, they’re available for more Commerce domains. See [Get Started With Salesforce Commerce Extensions](https://developer.salesforce.com/docs/commerce/salesforce-commerce/guide/extensions.html).

Calls to the API services are triggered when shoppers click Checkout or revisit a checkout session from their browser. Store components that embed the Checkout APIs are implemented in Lightning Web Runtime.
