+
+Provide an endpoint framework allowing users to define their own custom endpoint.
+
+Thanks to endpoint mixin the endpoint records are automatically registered as real Odoo routes.
+
+You can easily code what you want in the code snippet.
+
+NOTE: for security reasons any kind of RPC call is blocked on endpoint records.
