## Bulk CMS authoring

The [Create Collection Items](/data/reference/cms/collection-items/staged-items/create-item) endpoint now supports bulk creation. You can create multiple CMS items in a single request by passing an array of items to the `items` property. This provides a more efficient way to create multiple items while maintaining compatibility with the existing [bulk Create Items endpoint](/data/reference/cms/collection-items/bulk-items/create-items).

## Introducing the `localeId` Parameter

Webflow is standardizing query parameter naming by introducing `localeId` as the preferred parameter name, replacing `locale`. For backward compatibility, the `locale` parameter will continue to work, but it's recommended to use `localeId` in all new implementations. This change affects the following endpoints:

* [List Pages](/data/reference/pages/list)
* [Get Page Metadata](/data/reference/pages/get-metadata)
* [Update Page Metadata](/data/reference/pages/update-page-settings)
* [Get Page Content](/data/reference/pages/get-content)
* [Update Page Content](/data/reference/pages/update-static-content)
