# UpdatePrivateEndpointRequest

Only the fields present change. `base_url`, `upstream_model_id`, `declared_zdr` and `declared_region` are accepted on a draft only; `pricing` and `declared_parameters` replace their value; `settings` is itself a partial update where `null` clears a limit or restores the provider default.

## Fields

| `DeclaredParameters` | \[][components.PrivateEndpointDeclaredParameter](../../models/components/privateendpointdeclaredparameter.mdx) | ➖ | Parameters the upstream supports beyond the tested ones.
