I got the task to integrate the systems of our old shop to Shopware 6. So I have to deal with the Admin API. The documentation says:
The Admin API is designed in such a way that all entities of the system can be read in the same way. Once an entity is registered in the system, it can be written and read via API
https://developer.shopware.com/docs/guides/integrations-api/admin-api/reading-entities
How do those entities work? Is there a list/documentation of all default entities? Do I have to register the entities myself?
