OCAPI is designed to expose B2C Commerce resources to external applications and integration systems through RESTful APIs. A warehouse management system that needs to update inventory is therefore a strong OCAPI use case because inventory is enterprise data maintained by an external operational system and must be synchronized into Commerce.
Salesforce describes the OCAPI Data API as providing external applications with programmatic access to Commerce resources and administrative data operations. Inventory integration is a standard example of synchronizing Commerce with external inventory or fulfillment systems.
Extending a System Object Type definition with new attributes is a platform metadata/configuration activity normally performed through Business Manager or supported metadata import mechanisms, not an ordinary OCAPI runtime integration. Showing customer information on the storefront ' s native My Account page is also normally handled internally by SFRA controllers, models, templates, and the B2C Commerce Script API rather than calling OCAPI from the same storefront application.
Using OCAPI for the warehouse system preserves a clear integration boundary: the external application authenticates through the API and exchanges inventory data without being coupled to storefront presentation code.
