Generic REST

Jmix provides a generic REST API that allows you to work with data model entities and business services without writing REST controllers on the backend. It automatically exposes endpoints for the following functionality:

  • CRUD operations on entities.

  • Calling of registered service methods.

  • Execution of predefined JPQL queries.

  • Uploading and downloading files.

  • Returning information about the data model.

  • Returning information about the current user and their permissions.

You can explore the generic REST endpoints using the Swagger UI page at https://docs.jmix.io/openapi/2.3

REST API uses the OAuth2 protocol for authentication and supports anonymous access. All REST API endpoints respect data access constraints imposed by security.

The Generic REST add-on does not fully support multitenancy. It doesn’t separate entity instances by tenants.

Installation

Generic REST API is shipped as an optional add-on. To install it automatically through Jmix Marketplace, follow instructions in the Add-ons section.
