When working with content entities and the PATCH method, the endpoint is the same as the GET method path. The current user's access is checked to see whether they have the permission to update the entity type and each of the submitted fields provided in the request body.

Each field provided will be updated on the entity and then validated. If the entity is validated, it will be saved. On a successful save, an HTTP 200 response will be returned with the entire updated entity's content.
