CRUD operations with the Entity Service API#

The Entity Service API is built on top of the the Query Engine API and uses it to perform CRUD operations on entities.

The uid parameter used in function calls for this API is a string built with the following format: [category]::[content-type] where category is one of: admin, plugin or api.

Examples:

A correct uid to get users of the Strapi admin panel is admin::user.
A possible uid for the Upload plugin could be plugin::upload.file.
As the uids for user-defined custom content-types follow the api::[content-type] syntax, if a content-type article exists, it is referenced by api::article.article.
